As the demand for precision strikes in modern warfare continues to increase, guided weapons are being used more widely.cell phone jammer However, as one of the core technologies of these weapons, the GPS navigation system is facing a huge threat from signal jammers. In recent years, low-cost, high-efficiency GPS jammers have continued to emerge, posing a threat not only to military operations, but also to civil aviation and daily transportation systems.

Threats from GPS jammers
The basic principle of GPS jammers is to cover the weak signals of GPS satellites by emitting strong signals, so that the receiver loses its navigation ability.Wifi jammer In recent years, many countries, from North Korea to Russia, to China and Iran, have been actively developing and deploying jamming technology. drone jammer In 2011, North Korea used Russian-made equipment to implement GPS jamming on South Korea, causing some military equipment to fail. In the same year, Iran captured the US RQ-170 drone through GPS spoofing technology, showing its maturity in the field of electronic warfare.
Such threats do not only exist on the battlefield. In 2013, a truck driver in New Jersey, USA, used a low-cost GPS jammer to conceal his whereabouts, accidentally affecting air traffic control at Newark Airport. This shows that even small jammers can have a serious impact on critical infrastructure.
Manufacturers’ Response
In response to the growing threat of GPS jamming, the military and its industry partners have taken a variety of measures to improve the anti-jamming capabilities of guided weapons. For example, Boeing’s JDAM guidance kit originally relied entirely on GPS-assisted navigation, but now has introduced laser guidance technology. Even when the GPS signal is denied, these weapons can continue to aim at the target through laser sensors.
