BAE Systems recently received a $13 million contract to protect U.S. F-15E aircraft from GPS signal jamming and spoofing with its Digital GPS Anti-jam Receiver (DIGAR). The aircraft is the second U.S. Air Force fighter platform to receive DIGAR GPS upgrades, with the F-16 Fighting Falcon the first.
DIGAR uses advanced antenna electronics, high-performance signal processing, and digital beamforming for enhanced GPS signal reception and jamming protection, according to a news release, capabilities that are critical for high-speed aircraft like the F-15E and F-16. It also provides advanced GPS capabilities for intelligence, surveillance, and reconnaissance aircraft as well as multiple unmanned aerial vehicles.
“Modern airborne missions require accurate positioning and navigation data, and GPS systems must be able to withstand adversaries’ best disruption efforts,” said Greg Wild, BAE Systems Navigation and Sensor Systems product line director, according to the release. “Our DIGAR antenna electronics are trusted to protect these platforms in contested environments.”
