The blue or the red one?

This my blog about my workings for the distributed ground station network.

Once more in the history of this project i got some magic smoke ... Because our current hardware platform, the bladeRF, is very complex, i decided to do some of the basic FPGA tests on a cheaper and really simple FPGA- Evaluation board. Now the board has arrived and first of all i connected it to a power source ... booom! ... magic smoke and no flashing lights. That's the problem with "Made in China", it's cheap, but the documentation is very bad and so i didn't know that the polarity was reversed. But i'm lucky and now after desoldering a broken capacitor the board is working and ready for the first live tests of all the things currently running only in my simulations.

Testing the NMEA-Output of the GPS-Reciever was successfull. The position and time, currently transfered as raw data directly over an arduino to my pc, will be give us information about the position of a DGSN ground station and the exact timestamp which is needed for calculation of the satellites position. In future all the evaluation of the GPS data will be done hardwired by a fpga chip. The needed coding is currently in develop ...

First of all, i'm sorry. I wanted to share my progress at Google Summer of Code 2014 (GSOC14) and the Distributed Ground Station Network (DGSN) on this blog. Now more than a half of the time of GSOC14 is over an there's nothing yet i posted so far. But in the next few days i will catch up and presenting all what i've done so far, i promise!
