Mystery GPS jammer in Iran becomes test for NASA satellites’ capabilities
NASA satellites have demonstrated the ability to locate GPS jammers, particularly one operating in Iran. This capability is significant for monitoring areas at risk for aircraft and maritime navigation. The experiment showed that the Cyclone Global Navigation Satellite System (CYGNSS) was more accurate than the NASA-ISRO Synthetic Aperture Radar (NISAR) in identifying the jammer's location.
- ▪NASA satellites can identify approximate locations of GPS jammers.
- ▪The experiment focused on a GPS jammer active near Shiraz, Iran.
- ▪CYGNSS located the jammer within 4.33 kilometers of the actual position, outperforming NISAR.
