Mystery GPS jammer in Iran becomes test for NASA satellites’ capabilities
NASA science satellites show dual use in locating sources of GPS interference.

TL;DR
- NASA satellites designed for cyclone and ice sheet observation can identify approximate locations of GPS jammers.
- Experiments using CYGNSS and NISAR satellites located a jammer in Iran within a few kilometers.
- CYGNSS proved more accurate than NISAR in locating the jammer.
- This capability could help monitor areas with GPS interference, benefiting aircraft and ship navigation.
- GPS jamming is a growing problem affecting global shipping and air traffic.
