NASA satellites detect Iranian GPS jamming in unexpected capability test
Source: Ars Technica
NASA's Earth-observing satellites, built to track weather and climate phenomena, can detect GPS denial systems by measuring wind speed anomalies that only occur when positioning signals fail. This accidental dual-use discovery shows how civilian space infrastructure can monitor military and intelligence activities, while demonstrating that adversaries cannot jam GNSS signals without leaving observable atmospheric signatures. Deploying such weapons in populated areas creates detectable consequences.
