Starlink Signal Science
Scientists from TU Graz have developed a groundbreaking method to extract climate and Earth observation data from Starlink and similar satellite communication signals using the Doppler effect. Despite challenges like lack of signal structure information and orbit data, they've successfully measured satellite positions with surprising accuracy (within 54 meters) using constant signal tones. This technique opens up new opportunities for real-time monitoring of sea levels, weather events, and gravitational shifts—critical for climate research. Future improvements could increase accuracy to a few meters, revolutionizing global Earth observation using existing satellite megaconstellations.
