Protecting the U.S. Military From GPS Jamming and Spoofing

Protecting the U.S. Military From GPS Jamming and Spoofing

U.S. troops first used GPS to create an informational and navigation advantage on the battlefield during the 1991 Persian Gulf War. The success of GPS and the PNT advantage led to a huge increase in the technology’s use by the military.

However, as the United States has relied more on GPS, any absence of these Positioning, Navigation, and Timing (PNT) capabilities has led to greater risk. U.S. forces who need GPS to provide critical, precise information may lose their operational advantage without it.

U.S. adversaries have learned that this vulnerability can be exploited. If they can deny U.S. forces the advantage of GPS-based PNT capabilities, they can reduce their effectiveness.

This white paper from C4ISRNET discusses how preparation and countermeasures can assure U.S. forces maintain critical capabilities.
