professional indoor bleacher seating for different stadiums, gymnasiums

In the 1960s and 1970s, modern versions of the kiva—the circular, sunken stone structure with tiered bench seating that Puebloan American Indians built for spiritual and social gatherings—began appearing in open-plan schools. Kids loved the kiva, analogous to stadium seating, because it was climbable and inherently social. Educators loved how it functioned as a school’s town square, accommodating everything from planned events to playtime. Now, progressive companies—whose goal, much like that of schools, is to facilitate productivity while maintaining, ideally, at least a facade of enjoyment—have come to embrace it for many of the same reasons.

Stadium scoreboards have been renovated by college in the sample in the past five years. including 62.5% of colleges with a stadium seating capacity of 2.500 to 10,000 and 71,43% of colleges with a seating capacity or more than 30,000, Field lighting has been renovated by 22% or colleges with stadiums built less than 20 years ago, 35% or colleges with stadiums built 20 to 60 years ago and 38.89% of colleges With stadiums built more than 60 years ago. Altogether, 32.14% colleges in the sample have renovated field lighting in their sports stadium in the past five years.

Another is the Etihad Stadium, in Melbourne, Australia, which accommodates 50,000 spectators for rugby (rectangular pitch), cricket (oval pitch) and Australian rules football (oval pitch). The pre-cast concrete upper tiers are fixed in an oval shape, but the steel lower tiers, slightly curved in plan, can move forward on wheels over the cricket pitch to be closer to the rugby tou ine. This stadium also has a closing roof to allow sports to be played in any weather conditions and to host a wider range of non-sports events. In the case of stadia used for both soccer and athletics, continental European spectators do not seem to mind the great distance between spectator and pitch created by the intervening athletics track, whereas in Britain there is a tradition of close viewing which most interested parties wish to preserve.

Aluminum Bleachers used for outdoor events

Bleachers used for outdoor events are typically lightweight, aluminum portable units that are foldable. They are unlike the chair and riser combination that is used indoors.

Construction

Although not completely consistent with all manufacturers, portable bleachers generally have a rise of 8 in. (20 cm), a horizontal depth of 24 in. (60 cm), and seats have a rise above the tread of 17 in. (43 cm). Seat sizes are 1.5 to 2.0 in. X 9.5 to 10.0 in. (3.75 to 5 cm X 24 to 25 cm}, all usually constructed of anodized aluminum with end caps. Guardrails arc usually anodized pipe, 1.5 to I .675 in. (3.75 to 4.2 cm) diameter and 42 in. (106 cm) h'gh. These arc normally fitted to the backs, sides, stairs, and fronts of bleacher sections. Sections also come in more or less standard sizes of 3, 5, 10, and 15 row X 15 ft (4.5 m) sections, elevated or non-elevated, with varlous guardrail options, as well as accessibility options to mccr Amcncans with Disabilities Act {ADA) requirements. See Figure 9.6 for an example of a 10-tier, elevated section.

safety

The current guiding standard for the design, construction, and inspection of portable bleachers in the USA is contained in IC.C/ANSI 300-2002, Bleachers, Folding and Telescopic Seating, and Grandstands. The International Code Council (ICC.) Initiated the development of this stand-alone standard to address bleacher safety, after the issue was highlighted when two US congressional rep resentatives the Consumer Product Safety Commission to develop such regulations, following a study of deaths and injuries resulting from falls from bleachers. For example, in 1999 in the USA, there were an estimated 22, 100 bleacher-associated injuries treated in hospital emergency rooms.

LESSONS FROM RECENT AMERICAN STADIUM DESIGNS

In exploring how new British stadia should be designed, it is instructive to see how new stadia have developed in North America since the 1960s. During the 1960s and 1970s new stadia in the United States tended to be built on open, edge of city sites allowing the new stadium to be surrounded by vast expanses of car parking which was provided to meet the expectations of a public who lived and breathed the automobile. These stadia were often designed as combined sports use stadia which would be convertible between baseball and American football use. During the same period some of the new stadia were built as 'dome' stadia totally enclosed by a fixed roof and with artificial grass fields.

By the 1990s new stadia were being designed dedicated for baseball or American football use and many of these were destined to supersede stadia built only 30 years previously for combined use. Two reasons can explain this reversal. First, baseball fans found the combined stadia lacked the character ofa Vreal' baseball park with the classic horse-shoe outdoor grandstand configuration and open outfield. Second, major league baseball and American football clubs each became economically strong enough in their own right to justify building separate stadia. One of the first new generation baseball parks to be built was the Oriole Baseball Stadium in Baltimore. Whilst incorporating the type of up-to-date amenities to meet the demands of the modern day spectator the architecture of the stadium reintroduced some of the classic baseball park vernacular, such as exposed steel framework and an asymmetric seating bowls which help evoke a sense of the game's traditions. Other new baseball parks at Cleveland (Jacob's Field) and Atlanta (Turner Field) also feature similar 'retro' style. At Baltimore, the design of the stadium was also effectively integrated into the urban fabric of the city's downtown district with views of an old warehouse featured in the stadium planning.

Programming options for PLC include industrial panel pc and computer

Program memory is the capacity for control software storage. Available inputs for programmable logic controllers include DC, AC, analog, thermocouple, RTD, frequency or pulse, transistor, and interrupt inputs. Outputs for PLC include DC, AC, relay, analog, frequency or pulse, transistor, and triac. Programming options for PLC include front panel, hand held, and computer.Programmable logic controllers can also be specifi ed with a number of computer interface options, network specifi cations, and features. PLC power options, mounting options, and environmental operating conditions are all also important to be considered.

PLCs are usually available in these three general types:

(1) Embedded.

The embedded controllers expand their fi eld bus terminals and transform them into a modular PLC. All embedded controllers support the same communication standards such as Ethernet TCP/IP. The industrial embedded pc and compact operating units belonging to PLC product spectrum are also identical for all controllers.

(2) PC-based.

This type of PLCs is of slide-in card for the PC that extends every PC or IPC and transforms it into a fully fledged PLC. In the PC, the slide-in card needs only one PCI bus slot and runs fully independently of the operating system. PC system crashes leave the machine control completely cold.

(3)Compact.

The compact PLC controller unites the functions of an operating unit and a PLC. To some extent, the compact controller already features integrated digital and analog inputs and outputs. Further fi eld bus terminals in the compact PLCs can be connected via an electrically isolated interface such as CANopen.

Memory considerations

The two main factors to consider when choosing memory are the type and the amount. An application may require two types of memory: nonvolatile memory and volatile memory with a battery backup. A non volatile memory, such as EPROM, can provide a reliable, permanent storage medium once the program has been created and debugged. If the application will require on-line changes, then it should probably be stored in read/write memory supported by a battery. Some controllers offer both of these options, which can be used individually or in con junction with each other. The amount of memory required for a given application is a function of the total number of inputs and outputs to be controlled and the complexity of the control program. The complexity refers to the amount and type of arithmetic and data manipulation functions that the PLC will perform. For each of their products, manufacturers have a rule-of-thumb formula that helps to approximate the memory requirement. This formula involves multiplying the total number of I/O by a constant (usually a number between 3 and 8). If the program involves arithmetic or data manipulation, this memory approximation should be increased by 25–50%.

(c) Software considerations.

During system implementation, the user must program the PLC. Because the programming is so important, the user should be aware of the software capabilities of the product they choose. Generally, the software capability of a system is tailored to handle the control hardware that is available with the controller. However, some applications require special software functions that are beyond the control of the hardware components. For instance, an application may involve special control or data acquisition functions that require complex numerical calculations and data-handling manipulations. The instruction set selected will determine the ease with which these software tasks can be implemented. It will also directly affect the time required to implement and execute the control program.

Reviewing three typical GPS manufacturer software

GPS receiver manufacturers have a number of software products available for their models that support maps. So you have a better understanding of what types of maps are available, here are the different map software packages that the major GPS receiver manufacturers offer. Read on to discover what types overs. For more information and in-depth reviews of GPS receiver manufacturer map products, including screenshots, visit http://gpsinformation.net.

GPS receivers sold in different parts of the world typically have different basemaps. For example, a GPS receiver sold in Germany will have a more detailed basemap of Europe, compared with the same model of receiver sold in the United States. I want to clarify a point that sometimes confuses current or prospective GPS receiver owners: Each of the major GPS receiver manufacturers has their own line of map products that all sound pretty similar. Here they are:

Magellan MapSend Magellan manufactures the popular Meridian and SporTrak GPS receiver lines. The Meridian receivers use memory cards for map storage, and the SporTrak models have a fixed amount of internal memory to store maps. Software products that you can use with Magellan mapping GPS receivers include the following. Information about all these products is available at the Magellan Web site. MapSend DirectRoute

This software package provides street maps, POIs, automated street routing, and turn-by-turn directions for most Meridian and SporTrak receivers. With automated street routing, you can enter a starting and destination street address, and the GPS receiver will provide you with a route, including street directions. Most GPS receivers give you a straight-line route between two points, but Magellan upgraded the firmware on a number of their receivers to support both straight-line and street routes when MapSend DirectRoute maps are uploaded. Versions of the software are available for the United States, major cities in Canada, and Europe.MapSend BlueNav charts These are nautical charts with detailed coverage areas and enhanced marine navigation information, such as currents, tides, and port services. Charts, available for a number of coastal areas in North America and Europe, can be purchased on CD-ROM or preloaded SD memory cards.

MapSend Topo The Topo product is designed for outdoor recreation use :100,000 scale topographic maps of the United States, including trails, roads, rivers, lakes, coastlines, and POIs. After you upload the maps, you can display elevation profiles on your GPS receiver for roads, trails, and user-created routes.

MapSend Streets & Destinations

Magellan’s original road map software package has versions available for the United States and Canada. If you’re looking for street navigation software for your Magellan, I recommend MapSend DirectRoute because of its autorouting features and more cur-rent NAVTECH maps. Choose Streets & Destinations if you have an older GPS receiver that isn’t compatible with DirectRoute or if you’re on a tight budget.

MapSend WorldWide Basemap This map software package expands your GPS receiver’s built-in basemap coverage to other international regions. Each basemap region has basic map features such as cities, highways, waterways, railroads, national boundaries, and shorelines.

Lowrance MapCreate Lowrance was the first manufacturer to offer a GPS receiver with uploadable maps. The company continues the electronic map tradition with its current line of iFINDER handheld GPS receivers; which use memory cards to store maps.

If you own a Lowrance GPS receiver or are considering purchasing one, here are the map products you can use:

MapCreate

MapCreate is Lowrance’s primary map program for creating GPS receiver maps of the United States. In addition to street maps and points of interest, MapCreate also has an extensive database of navigation aids, wrecks, and obstructions for marine use. One nice feature of MapCreate is that you can select polygon map regions to upload, which maximizes map storage space. Although MapCreate currently doesn’t offer autorouting and turn-by-turn directions, Lowrance does plan to offer this feature in the future.

FreedomMaps

In addition to maps on CD-ROM, Lowrance also offers the FreedomMaps product line, comprising memory cards preloaded with maps of the United States, Europe, and Canada. Regional maps come on 128MB and 256MB memory cards that you just plug into your GPS receiver; no software or CD-ROMs are required.

Navionics charts

Navionics (www.navionics.com) is one of the largest producers of electronic nautical charts. Navionics Gold and Classic charts and fishing HotMaps are all available on MMC memory cards and are also compatible with the iFINDER Pro GPS receiver.Garmin MapSource

Like the other GPS receiver manufacturers, Garmin offers a number of different types of maps for its products. Unlike Magellan and Lowrance, however, Garmin doesn’t use memory cards in its current line of handheld GPS receivers. Any maps that you upload must be able to fit into whatever fixed memory the GPS receiver has available for storage.

Although Garmin doesn’t use commonly available SD or MMC memory cards in its GPS tracking device, the company is using newer technology to make uploading maps quicker. Recent Garmin products feature USB connectivity, which is considerably faster than uploading a map to a GPS receiver through a PC serial port.

If you own a Garmin GPS receiver or are considering purchasing one, here are some of the mapping software packages that you can use. Detailed information about all is available from the Garmin Web site.

MapSource City Select

City Select contains street maps and points of interest and is designed to work with Garmin GPS receivers that support autorouting , such as the GPSMAP 196 and GPSMAP 60C/60CS. The three versions of the product are available for North America, Europe, and South Africa.

  Map Source Metro Guide

Metroguide is similar to City Select but is designed for Garmin GPS receivers that don’t support auto-routing (such as the e-Trex Legend and Vista). Four versions of this product are available, providing street maps for the United States, Canada, Australia, and Europe.

  MapSource WorldMap

This software provides basic international maps that expand the default basemap coverage that comes with your

electronic tracker

.

GPS receivers sold in different parts of the world typically have different basemaps.

  MapSource Bluechart

BlueChart products are Garmin’s nautical charts and are available in regional versions that cover the Americas as well as the Atlantic and Pacific Oceans.

  Fishing Hot Spots

Fishing Hot Spots are maps of popular fishing areas in North America with depth contours, shoreline details, boat ramp information, and fishing tips. The maps are sold for multistate regions.

Minnesota LakeMaster ProMap

Designed specifically for GPS receiver owners who fish in the Minnesota area, this map product has maps of popular lakes and includes three-foot contours with underwater structure detail, islands, reefs, points, bays, access points, and marinas.

GPS Tracking Device for electronic monitoring possible option

Since the 1960s, the location of offenders under community supervision has been monitored with the assistance of

electronic tracker

. Increasingly, electronic monitoring relies on technology that uses the global positioning system (GPS) to monitor offenders. The adoption of GPS monitoring has been facilitated by court decisions that find this form of surveillance can be employed without violating the offender’s constitutional rights. In fact, some states now require the use of GPS for certain perceived high-risk offender groups, particularly sex offenders. GPS monitoring has also become more common in the supervision of domestic violence and drug offenders, as well as supervises with gang affiliations. Although it has become an accepted part of community supervision, GPS monitoring is not without its complications.

GPS technology was created by the U.S. Department of Defense in the 1970s. Over time, GPS tracking device has been adapted for nonmilitary purposes and has become more affordable and portable. Usually combined with radio-frequency receivers, computer technology, and cell phone service, GPS utilizes satellites orbiting the earth to communicate information in real time (or near real time) about geographic location. In community corrections, offenders are generally required to wear a tamper-resistant, battery-operated radio-frequency transmitter around the ankle. They also must carry a

portable GPS Tracker

unit with them, usually strapped around the waist or shoulder or carried by hand. If the offender fails to carry or attempts to disable the GPS tracking unit, enters a prohibited area, or leaves his or her home without authorization, an alert is issued to a central monitoring unit, overseen by corrections professionals or a private contractor. The offender’s supervisor is then notified. Even if the offender has not acted in violation of his or her supervision conditions, the supervisor can track the offender’s movements from stored data, which might be useful in identifying, or eliminating, the offender in reports of new crimes. Some newer GPS units can also determine alcohol consumption.

Passive, active, and hybrid GPS monitoring systems are currently in use. Unlike active systems, which constantly relay real-time location information via cell phone service to a central monitoring system, passive systems relay information only when the offender connects the

GPS Tracking Device

unit to a docking station, usually connected with a land-line telephone. Hybrid systems are also available; these report information every few hours, and if an alert is detected, the real-time active system is triggered. GPS programs attempt to balance the integration of offenders into the community with public safety and security. GPS monitoring is significantly cheaper than incarceration. A cost analysis conducted in Florida estimated that enrolling all sex offenders in a GPS monitoring program would cost $8 million, but incarcerating them would cost $56 million. Also, to the degree that GPS monitoring diverts offenders from incarceration, it can lessen problems associated with overcrowding in jails and prisons.

JC600 3G Android GPS Navigation Rearview Mirror DVR Android Rearview Mirror can be applied to any private cars. Google Map navigation with 3G network will be your best friend on the road. GPS+AGPS Dual Positioning System, features of 1080P front camera and D1 back camera make sure every detail to be recorded and to provide full evidence in conflict. In addition, the Android 4.4 operating system provides possibilities for easy integration of new software, to make the device to be smart while you are driving.

JC900 3G Android Google Navigation Rearview Mirror Monitor JC900 can take input from a separate camera mounted on the rear of the car, which serves as a live rear view for the driver when the car is in reverse. It also ties to a forward-facing camera that works as an incident recorder in case of any crash. What makes it different is the additional inward-facing camera, acting as a witness on what happen in the car, and for driver recognition as well.

All the GPS trackers can be automatically connected to Jimi. There is no need to write ports and gateways. As we can see, in most cases GPS tracking business buys 3G devices just because the mobile operator is cancelling 2G networks. That is it. It has nothing to do with their need for high speed. 2G is enough for GPS tracking devices and getting telemetry data.

GPS stands for Global Positioning System

GPS stands for Global Positioning System, which is a nifty satellite system that tells you your location anywhere on planet earth. This part is all about GPS. We’ll start with a broad overview of the satellite system and work our way back down to earth and discuss handheld, consumer GPS Tracker For Car. By the end of the part you’ll understand the technology behind GPS (without needing to be a rocket scientist), be able to navigate through the jungle of GPS receivers on the market, and have the skills and knowledge to practically use a GPS receiver without being intimidated or confused by it. You’ve heard about GPS and probably know that it has something to do with handheld gadgets and satellites that tell you where you’re located. That’s great for starters, but to understand and use GPS personal tracker, you need a bit more detailed knowledge. Follow this passage to go through some of the fundamentals of GPS so you have a better grasp of what it is and how you can use it. What is GPS?GPS stands for Global Positioning System. A special radio receiver measures the distance from your location to satellites that orbit the earth broadcasting radio signals. GPS can pinpoint your position anywhere in the world. Pretty cool, huh? Aside from buying the receiver, the system is free for anyone. You can purchase an inexpensive GPS Tracking Device, pop some batteries in it, turn it on, and presto! Your location appears on the screen. No map, compass, sextant, nor sundial is required. Just like magic. It’s not really magic, though, but has evolved from some great practical applications of science that have come together over the last 50 years. Other satellite Global Positioning Systems are either in orbit or planned, but this book uses the term GPS for the Global Positioning System operated by the United States government. Military, government, and civilian users all over the world rely on GPS for navigation and location positioning, but radio signals have been used for navigation purposes since the 1920s. LORAN (Long Range Aid to Navigation), a position-finding system that measured the time difference of arriving radio signals, was developed during World War II. The first step to GPS came way back in 1957 when the Russians launched Sputnik, the first satellite to orbit the Earth. Sputnik used a radio transmitter to broadcast telemetry information. Scientists at the Johns Hopkins Applied Physics Lab discovered that the Doppler shift phenomenon applied to the spacecraft — and almost unwittingly struck gold. A down-to-earth, painless example of theDoppler shift principle is when you stand on a sidewalk and a police car speeds by in hot pursuit of a stolen motorcycle. The pitch of the police siren increases as the car approaches you and then drops sharply as it moves away. American scientists figured out that if they knew the satellite’s precise orbital position, they could accurately locate their exact position on Earth by listening to the pinging sounds and measuring the satellite’s radio signal Doppler shift. Satellites offered some possibilities for a navigation and positioning system, and the U.S. Department of Defense (DoD) explored the concept.           By the 1960s, several rudimentary satellite positioning systems existed. The U.S. Army, Navy, and Air Force were all working on independent versions of radio navigation systems that could provide accurate positioning and all weather, 24-hour coverage. In 1973, the Air Force was selected as the lead organization to consolidate all the military satellite navigation efforts into a single program. This evolved into the NAVSTAR (Navigation Satellite Timing and Ranging) Global Positioning System, which is the official name for the United States’ GPS program. The U.S. military wasn’t just interested in GPS for navigation. A satellite location system can be used for weapons-system targeting. Smart weapons such as the Tomahawk cruise missile use GPS in their precision guidance systems. GPS, combined with contour-matching radar and digital image-matching optics, makes a Tomahawk an extremely accurate weapon. The possibility of an enemy using GPS vehicle tracking device against the United States is one reason why civilian GPS receivers are less accurate than their restricted use military counterparts. The first NAVSTAR satellite was launched in 1974 to test the concept. By the mid 1980s, more satellites were put in orbit to make the system functional. In 1994, the planned full constellation of 24 satellites was in place. Soon, the military declared the system completely operational. The program has been wildly successful and is still funded through the U.S. DoD.

Vehicle GPS tracking systems for Moving Vehicles

NRL collects the GPS data along with the laser tracking data for inter comparison studies. Tracking data from the GPS Control Segment stations, USNO, the broadcast position data and DMA precise ephemerides are collected. These are continuous data over the in~rbit operation of the satellites. To utilize the GPS derived tracking data for inter comparison with the laser derived data, the local clocks at the GPS Monitor Station sites must be accounted for since they are the basis for the GPS tracking measurements. In GPS itself these clocks are accounted for by the use of GPS Time which is a common synchronization time computed at the MCS. However, the GPS ranging measurements are directly related to the local clocks whose performance must be removed if the satellite clock is to be isolated from the satellite orbital position and evaluated. The laser data is independent of this influence on ranging measurements since the local clock is used for time tagging.

To determine the performance of the station clocks to the Master clock at USNO, common view time comparisons with USNO were made to the Colorado Springs, Hawaii and Ascension stations. Navigation users would not be aware of these changes since they use GPS Time which is a computed time accounting for these changes. For this experiment, removal of the local clock and the satellite position error by laser derived positions from the GPS tracking devices' data will leave the satellite clock as the principal error component.

The field testing of VISAT, a prototype mobile highway mapping system which has been developed in cooperation between the University of Calgary and Geofit Inc. in Laval, Quebec, is described in this paper. The integration of inertial technology and GPS satellite receivers with an array of ceo cameras ( camera rear view mirror ) has resulted in a system that is capable of mapping all visible objects within a 50 m radius of the moving vehicle. Extensive tests in city centers, suburban areas, and rural areas have shown that the system works very reliably and that the expected positioning accuracy of 30 cm is surpassed in many cases. A more detailed analysis of the results shows that the RMS positioning error in acrosstrack direction and height is actually between 5 and 10 cm, while the along-track error is usually larger. Due the restrictions in the length of the paper, only some of the major results can be highlighted.

VISAT system integrates a cluster of video cameras (

rearview mirror with camera

,

Android rear view camera

), an Inertial Navigation System (INS), and satellite receivers of the Global Positioning System (GPS). The system carrier is currently a van, but airborne or marine applications can be realized in a similar way. The overall objective of the VISAT development was to build a precise multi-sensor mobile mapping system that could be operated at speeds of up to 60 Ian per hour and would achieve an accuracy of 0.3 m (RMS) with respect to the given control and a relative accuracy of 0.1 m (RMS) for points within a 50 m radius. This accuracy is required in all environments including inner cities, where stand-alone GPS is not reliable. Accuracy optimization must therefore be done with a view to total system performance, while system design has to be optimized with a view to isolating the error contribution of each sensor. The data flow has to be streamlined to facilitate the subsequent feature extraction process and transfer into a GIS system.

Rearview mirror camera is successful in reducing crimes

Many security consultants and security firms are hired to advise taxi companies on methods to help themselves. Situational crime prevention measures, such as partitions between drivers and passengers, video cameras, and

GPS rearview mirror

, are possible solutions that can reduce the risk to drivers. The most recent statistics from the U.S. Bureau of Labor Statistics reported that cab drivers are ten times more likely to be killed on the job than the average worker. The use of electronic video surveillance (surveillance and security cameras and closed-circuit television (CCTV) systems) has increased rapidly in both the private security industry and law enforcement. Electronic video surveillance systems can passively record and play back video at certain intervals, be actively monitored by security personnel, or be used in a combination of these methods. Some evidence suggests that video surveillance is successful in reducing and preventing crimes and is helpful in prosecuting criminals.

Recall that, in the London Underground bombings in 2005, video from the vast network of public surveillance cameras helped police identify the suicide bombers within days. Electronic video surveillance has several objectives, including a reduction in crime and disorder, making people feel safer, and providing evidence for police investigations. Prior to using such surveillance, a basic security audit is generally conducted to determine whether the electronic video surveillance is needed and how it should be designed. The two basic recording processes in electronic video surveillance are videocassette recorders and digital recorders. A switcher allows switching between multiple cameras and multiplexes, allowing recording and displaying images of several cameras simultaneously. Surveillance cameras can operate in low-light and nighttime situations by using infrared (light that cannot be seen by the human eye) technology located at the camera head to provide “invisible” lighting for the camera’s use. VCR recorders had been standard in electronic video surveillance; however, this technology has had drawbacks, and tapes become damaged each time they are run through the VCR, resulting in an absence of detail. Digital video systems provide advantages to standard VCR recording in image quality and ease of use. The latest in CCTV technology is the digital video recorder (

Rearview Mirror DVR

).

A DVR records images directly to a conventional computer hard drive as bits of data, instead of recording analog images to a moving medium like VHS tape. This is fundamentally similar to the technology used in consumer products like TiVo and Ultimate TV. Digital recording is a relatively new technology and in a state of constant flux and evolution. DVRs are sensitive electronic components that are vulnerable to power strikes and electrical interruptions and that need to be carefully handled. Digitally stored images can be preserved indefinitely and can be replicated without loss of quality. Smart DVR also allow for simultaneous recording and playback, better picture quality than tape, and quick searches of stored data using a wide variety of parameters. Digital closed-circuit television is one of the fastest-growing segments of the security industry. There is debate in the electronics industry about the value and best use of DVRs; however, most experts believe that they make credible and effective event-based recording a reality. The management of CCTV footage is simplified and the effectiveness is enhanced. Many DVRs have network compatibility and can be programmed to connect to a remote site, over either a network or a dial-up connection. A copy of the video clip can then be transmitted, allowing security to quickly assess the site status. Digital recording also results in reductions in maintenance costs and wasted personnel hours spent searching for video clips.

Better Living Through GPS Tracking Devices

It was just a few years since the launch of the first GPS satellite. As the constellation grew—and, along with it, a method of tracking that further enhanced the ability of humans to observe and gather data—the question of sensory augmentation and the law would grow more urgent.

For an airport of its size, Newark Liberty is squeezed into a fairly small footprint. The team that set up the GBAS receivers found that the only spot at the airport that provided full coverage was next to a runway at the airport’s eastern edge. Each receiver sat within 200 meters of the New Jersey Turnpike.

The freeway’s centrality guarantees that a sizable amount of its traffic is always commercial vehicles. A significant number of these, it turned out, are driven by people who possess “personal privacy devices,” a euphemistic term for GPS jammers. The drivers carried these jammers to foil the tracking apparatuses set up by their bosses to monitor the whereabouts of employees. Although operating one is illegal, they are cheap—often under $100—and easy to obtain from Internet vendors. Small and innocuous, many plug right into a vehicle’s dashboard cigarette lighter. They form a little interference bubble in the area surrounding the jammer, stopping the GPS signal from getting through. This interference was disrupting the GBAS receivers.

The discovery came as a shock to the GBAS team. “We were generally aware of people with jammers in the cars,” says Sam Pullen, leader of the Stanford GPS Lab’s GBAS research group. “But we knew those devices were low-power. So we suspected there would be fewer bumps and that we’d rarely see them. We didn’t think about it that closely, but there was no reason to think that car-based jammers by themselves would be much more frequent than what we had seen previously.”

Authorities began a stakeout of the Turnpike. But pinpointing the source of the jammers was difficult, so the GBAS outages continued. On April 29, the effort finally paid off. Police were positioned on the Turnpike, near the runway, when the interference began. It seemed to coincide with the passing of a certain truck. They raced after it and motioned the driver to pull over. The jammer was right there on the dashboard. The driver made no attempt to hide it. In exchange for handing it over, the police let the driver go on his way with a warning.

Moving the GBAS array was not an option. No other spot could so effectively cover the airport. Instead, the team made some adjustments to the software, which mitigated the problem a bit, but not completely. Cars and trucks with GPS jammers continued to use the Turnpike, and sometimes they jammed the GBAS. Throughout the summer months, the team monitored the problem—the monotonous jamming blips from trucks passing through America’s most dangerous two miles.

Until one day in August, when the static suddenly got worse. By the second half of the 1980s, companies like Trimble and Qualcomm were exploring the market for GPS  tracking devices that would allow trucking companies to monitor their drivers’ whereabouts. A GPS tracker is simply a GPS receiver integrated into some kind of communication device that periodically transmits or records that location. The problem for early fleet management systems was not so much the GPS aspect, as it was finding radio frequencies usable over wide geographic areas to transmit the coordinates back to the monitoring centers. But the customers were there. Three years after it debuted, Qualcomm’s Omnitracs system had signed up about 100 trucking companies and was monitoring the whereabouts of 15,000 trucks. Drivers were required to enter messages onto a dashboard-mounted terminal. Satellite dishes on the trucks relayed the information to Qualcomm’s San Diego headquarters, which forwarded it to the driver’s dispatchers.

As cellular networks developed and the cost of access decreased, GPS tracking became a more realistic proposition. Between 1992 and 1997, U.S. Census Bureau “vehicle inventory and use” surveys found that the percentage of commercial trucks on the road being tracked electronically rose from roughly one in ten to nearly one in four. The process of tracking via GPS became much simpler. “A GPS tracking device is like a mini-cell phone, more or less,” says Ryan Driscoll, the marketing manager at GPS Insight, an Arizona-based company that designs GPS tracking software. At regular intervals, the device transmits the GPS reading to a monitor, either a live human or a computer that gathers and archives the location data.

By 2005, companies and government organizations were using GPS to track 1.3 million fleet vehicles. Analysts projected that the North American fleet management market alone would grow to $7 billion over the next few years. More than half of all fleets with 100 or more vehicles now use a GPS fleet management system—for companies with more than 350 vehicles, the adoption rate is approaching 60 percent. The worldwide fleet management industry, valued at $12 billion in 2014, is on track to be worth more than $35 billion by 2019, with Asian and Pacific markets showing the highest growth rates. In Delhi, a public-private partnership between the Indian government and an infrastructure investment company has installed GPS trackers on all 60,000 public rickshaws, to prevent drivers from gouging tourists by taking longer routes. In China, GPS tracking is used to control the black market in “gutter oil,” recycled cooking oil that is combined with industrial waste and other effluents, which may account for 10 percent of all cooking oil used in the country. GPS trackers on garbage trucks keep track of where oil is collected, so that officials can ensure that the amount collected does not mysteriously decrease before disposal.

Fleet management is one of the fastest-growing segments of the overall GPS industry, and the largest segment of the telematics industry—companies that specialize in processing and transmitting real-time data from vehicles. It has proven itself to be recession-proof. “Our businesses thrive in a bad economy,” Driscoll says. “When expenses are tight, they need this. They can’t afford to waste fuel. They can’t afford to pay drivers for wasted labor hours. They’ve got to shave as many costs around the entire operation as possible.”

Among the private trucking fleets that use portable GPS tracking device, two-thirds integrate the system with other data gathering, to analyze job performance. The most extreme example may be United Parcel Service, whose drivers—“among the most regimented workers in the country outside those on an assembly line,” according to labor journalist Jane Slaughter—use trucks outfitted with 200 telematics sensors, recording such metrics as how hard a driver brakes and how long it takes to deliver a package and get a signature. In much the same way that Todd Humphreys described GPS in a drone as the “bulwark,” surrounded by and supporting other navigation tools, GPS location tracking in fleets is the foundation supporting many kinds of telematics data. Perhaps a clue as to why vehicle GPS tracking device is so seductive as a gateway to other information is that fleet managers overwhelmingly rate “vehicle location” as the principal benefit of GPS tracking, far ahead of fuel consumption and cost control. As the sales manager of a GPS fleet management company put it, summing up the prevailing attitude of his clients, “I want to know my employees are working, not at the Circle K having a soda.”

How many GPS Receiver Features you may need to know?

A number of GPS receivers are on the market. Usually a GPS receiver with more features costs more.

GPS manufacturers have done a pretty good job making user interfaces easy to use. After you know the basic concepts of GPS receivers and are familiar with a manufacturer’s user interface, a GPS Tracking Device is usually as easy to use as a cellphone and easier to use than a personal computer.

Display and output

GPS receivers have three choices for information display or data output:

  Monochrome LCD screen: Most GPS receivers have a monochrome liquid crystal display (LCD) screen.

Color screen: These are especially useful for displaying maps.

Color screens usually have shorter battery lives than monochrome ones.

  No screen: Some GPS receivers only transmit data through an expansion slot or a cable; a receiver with a cable is often called a mouse GPS receiver because it resembles a computer mouse.

  Such receivers are designed to interface with a laptop computer or PDA running special software. The picture below shows a DeLorme Earthmate GPS unit attached to a laptop. All

GPS data is sent to the laptop and processed there with mapping soft-ware. A Magellan SporTrak GPS receiver is shown on top of the laptop for comparison.

Most GPS receivers that have screens can output data to a PC or PDA.

A GPS receiver’s screen size depends on the receiver’s size. Smaller, lighter models have small screens; larger units sport bigger screens.

Generally, a bigger screen is easier to read. Different models of GPS receiver also have different pixel resolutions; the higher the screen resolution, the more crisp the display will be. For night use, all screens can be backlit.

Alarms A GPS receiver alarm can transmit a tone or display a message when you approach a location that you specify. This feature can be especially useful when you’re trying to find a place and visibility is limited by darkness or inclement weather — or you’re busy doing something else and aren’t looking at the GPS receiver screen.

Built-in maps Every GPS receiver has an information page that shows waypoints and tracks. The page is a simple map that plots travel and locations. It doesn’t show roads, geographic features, or man-made structures.

Some GPS receivers have maps that show roads, rivers, cities, and other fea-tures on their screens. You can zoom in and out to show different levels of detail. The two types of map receivers are

Basemap: These GPS tracker device have a basemap loaded into read-only memory that contains roads, highways, water bodies, cities, airports,railroads, and interstate exits.

Basemap GPS receivers aren’t expandable, and you can’t load more detailed maps to the unit to supplement the existing basemap.

Uploadable map: More detailed maps can be added to this type of unit (in either internal memory or an external memory card). You can install road maps, topographic maps, and nautical charts. Many of these maps also have built-in databases, so your GPS receiver can display restau-rants, gas stations, or attractions near a certain location.

Refer to the picture to see screens from a GPS receiver with a simple plot map and another GPS tracking device with an uploadable map.

GPS receivers that display maps use proprietary map data from the manufacturer. That means you can’t load another manufacturer’s or software company’s maps into a GPS receiver. However, clever hackers reverse-engineered Garmin’s map format. Programs on the Internet can create and upload your own maps to Garmin GPS receivers; GPS mapper is popular.

A handheld GPS receiver’s screen is only several inches across. The limitations of such a small display certainly don’t make the devices replacements for traditional paper maps.

Electronic compass All GPS receivers can tell you which direction you’re heading — that is, as long as you’re moving. The minute you stop, the receiver stops acting as a compass. To address this limitation, some GPS receivers incorporate an electronic compass that doesn’t rely on the GPS satellites. Operation Like with an old-fashioned compass, you can stand still and see which direction your GPS receiver is pointing toward. The only difference is that you see a digital display onscreen instead of a floating needle.

On some GPS receivers, you need to hold the unit flat and level for the compass to work correctly. Other models have a three-axis compass that allows the receiver to be tilted.

Paying attention to these factors can improve the performance and convenience of an electronic compass:

  Magnetic fields: Metal objects, cars, and other electronic devices reduce the accuracy of any electronic or magnetic compass.

  Battery life: Using an electronic compass can impact battery life. Some GPS receivers have settings that turn off the compass or only use it when the receiver can’t determine a direction from satellite data.

Calibration: Electronic compasses need to be calibrated whenever you change batteries. If your GPS unit has an electronic compass, follow your user guide’s instructions to calibrate it. Usually, this requires being outside, holding the GPS unit flat and level, and slowly turning in a circle twice.

Altimeter: The elevation or altitude calculated by a GPS receiver from satellite data isn’t very accurate. Because of this, some GPS units have altimeters, which provide the elevation, ascent/descent rates, change in elevation over distance or time, and the change of barometric pressure over time. Calibrated and used correctly, barometric altimeters can be accurate within 10 feet of the actual elevation. Knowing your altitude is useful if you have something to reference it to, such as a topographic map. Altimeters are useful for hiking or in the mountains.

Increasing accuracy

Some GPS receivers have features that allow you to increase the accuracy of your location by using radio signals not associated with the GPS satellites. If you see that a GPS receiver supports WAAS or Differential GPS, it has the potential to provide you with more accurate location data.

WAAS

WAAS is a Federal Aviation Administration (FAA) system, so GPS can be used for airplane flight approaches. The system has a series of ground-reference stations throughout the United States. These monitor GPS satellite data and then send the data to two master stations — one on the west coast and the other on the east coast. These master stations create a GPS message that corrects for position inaccuracies caused by satellite orbital drift and atmospheric conditions. The corrected messages are sent to non-NAVSTAR satellites in stationary orbit over the equator. The satellites then broadcast the data to GPS receivers that are WAAS-enabled.

GPS tracker device that supports WAAS has a built-in receiver to process the WAAS signals. You don’t need more hardware. Some GPS receivers support turning WAAS on and off. If WAAS is on, battery life is shorter (although not as significantly as it is when using the backlight). In fact, on these models, you can’t use WAAS if the receiver’s battery-saver mode is activated. Whether you turn WAAS on or off depends on your needs. Unless you need a higher level of accuracy, you can leave WAAS turned off if your GPS receiver supports tog-gling it on and off. WAAS is ideally suited for aviation as well as for open land and marine use. The system may not, however, provide any benefits in areas where trees or mountains obstruct the view of the horizon.

Uploading Firmware Revisions to Your Motorcycle GPS Tracker

Just like software vendors,

GPS tracking manufacturers

find bugs and add enhancements to their products. New versions of a GPS receiver’s operating system can be upgraded through the receiver’s firmware (the updatable, read-only software that’s embedded in a hardware device). Check that your GPS receiver’s firmware is current every few months or so, especially if your receiver is a newly released model. GPS manufacturers offer free downloads of firmware upgrades on their Web sites, and these bug-fixes or new features can definitely make your GPS receiver perform better.

To upgrade your firmware

1. Check the current version of your GPS receiver firmware.

Sometimes this is displayed when the GPS receiver is turned on, or it might be shown on an information page. Consult your user’s guide or the manufacturer’s Web site for specific instructions on how to get this information for your model.

2. Visit the manufacturers’s website and go to the software updates section.

If you have a JIMI GPS receiver, you can sign up for automatic e-mail notification of firmware upgrades at the JIMI Web site. I expect other GPS Device Manufacturer to start offering this service.

3. Find your GPS receiver model and check its manufacturer’s website for the latest firmware version.

If your firmware is older than the current version on the website, follow the online instructions to download the firmware installer. Usually, the higher the version number, the more recent the firmware version. Make sure that the firmware installer you download is for your GPS receiver model. If you upload firmware designed for a different model, plan on the GPS receiver not working until you load the proper firmware.

4. Follow the installation instructions that come with the downloaded file Usually firmware installation files come in two forms:

A standalone program that runs on your computer, connects to the GPS receiver, and sends the upgraded firmware to the receiver. You need to have a PC interface cable attached to both the computer and the GPS receiver.

A special file that you copy to a memory card. When the GPS receiver starts, it searches the card to see whether a firmware upgrade is present. If it is, the receiver uploads the upgrade. After the upgrade is successful, you can erase the firmware upgrade file from the memory card.

Upgrading a GPS receiver’s firmware is pretty easy; not too much can go wrong. About the only thing that can get you in trouble is if the GPS receiver’s batteries die midway through a firmware upload. A firmware upgrade usually only takes a few minutes to complete, but make sure that your batteries aren’t running on empty before you start. Some firmware update software works only on COM ports 1 through 4. If you’re using a USB adapter, (which is usually set to COM port 5 or higher) and are having problems connecting to the GPS receiver, try reassigning the existing COM ports to numbers higher than the USB adapter’s port; then set the adapter’s port number to 1. Refer to online Windows help (choose Start➪Help) and perform a search for device manager to get more information on changing device settings.
