NASA satellites originally designed for weather monitoring and Earth observation have demonstrated the ability to detect and approximately locate GPS jammers, as shown in an experiment identifying a mysterious jammer in Iran. While the technology cannot provide real-time monitoring or precise locations, it could help identify high-risk areas for aviation and maritime navigation affected by growing GPS interference. The study utilized NASA's CYGNSS and NISAR satellite systems, which detected signal disruptions caused by the jammer over a wide area.
Background
GPS jamming involves broadcasting strong radio signals to overpower legitimate GPS signals, creating navigation hazards for aircraft and ships. NASA's CYGNSS and NISAR satellites were originally designed for Earth observation but have shown potential for detecting such interference.
