With the gradual development and spread of GPS jamming technology, the stability of civilian and military GPS signals is facing severe challenges. The Coast Guard Navigation Center is responsible for coordinating the work of the Civilian GPS Service Interface Committee and has issued a number of risk notices on GPS jamming.cell phone jammer In a statement, the center warned of GPS signal instability in the area near the White Sands Missile Range, which is expected to affect a radius of up to 180 miles. This statement has attracted more attention to the threat of GPS jamming technology.signal jammer
GPS Jamming Investigation by the U.S. Department of Homeland Security
Against the backdrop of frequent GPS jamming incidents, the U.S. Department of Homeland Security has joined forces with the FCC and the FAA to track and eliminate illegal jamming sources. GPS jammerJohn Merrill, manager of the Department of Homeland Security’s Positioning, Navigation and Timing Program, said that small, inexpensive GPS jamming devices are widely circulated on the market and are difficult to locate, which undoubtedly increases the security risks of civilian and military GPS devices.

Application and expansion of Russian jammers on the Korean Peninsula
Geopolitical tensions on the Korean Peninsula have led to more frequent use of GPS jammers. North Korea has installed Russian jammers on vehicles near the border that can cover GPS signals within a range of 30 to 60 miles, and is developing jammers with a wider range. This expansion shows the importance and ability of state actors to interfere with GPS, posing a potential threat to regional and global security.
The impact of GPS jamming on military equipment and the need for optimization
Currently, the GPS chips equipped in the rifleman radios used by the U.S. Army only receive civilian signals and have poor anti-jamming capabilities. The U.S. Army is trying to test the actual performance of the equipment under jamming through network integration assessments. This assessment is not only a necessary means in a simulated actual combat environment, but may also promote future equipment upgrades. Compared with Russian jammers, civilian GPS signals are more easily jammed. Jules McNeff emphasized that although this option saves costs in the short term, in the long run, the vulnerability of the equipment will seriously affect combat effectiveness if it encounters jamming.
