Ships and planes are vulnerable to GPS jamming. The Iran war is revealing just how bad the problem is
Within 24 hours of the first US-Israeli strikes on Iran, ships in the region’s waters found their navigation systems had gone haywire, erroneously indicating that the vessels were at airports, a nuclear power plant and on Iranian land.

TL;DR
- Widespread GPS jamming and spoofing have affected over 1,100 commercial ships in UAE, Qatari, Omani, and Iranian waters following US-Israeli strikes on Iran.
- The interference has slowed marine traffic through the Strait of Hormuz, a critical global oil and gas export route.
- Jamming causes navigation systems to report false locations, with ships erroneously indicating they are at airports or on Iranian land.
- The problem has also impacted air travel, with flights experiencing GPS navigation jamming, forcing pilots to use paper maps and increasing workload.
- GNSS signals are vulnerable due to their open nature and weakening signal strength over distance, making them easy to overpower.
- While solutions like enhanced receivers and specialized antennas exist, they require time and money to implement, and alternative technologies are still under development.
- The "luxurious era" of unhindered GPS signals is over, necessitating a rapid adaptation to these new threats.
