BAE Systems has received a contract to supply an advanced global positioning system (GPS) technology for the US Air Force’s F-15E Strike Eagle.
The company will deliver its Digital GPS Anti-Jam Receiver (DIGAR) system under the $13 million agreement.
Integrating the DIGAR will secure the aircraft in signal-challenged environments and against aerial units with GPS disrupting capability.
“Modern airborne missions require accurate positioning and navigation data, and GPS systems must be able to withstand adversaries’ best disruption efforts,” BAE Systems Navigation and Sensor Systems Director Greg Wild said.
“Our DIGAR antenna electronics are trusted to protect these platforms in contested environments,” he added.
BAE’s DIGAR
The DIGAR is designed with advanced antenna electronics, signal processing, and digital beamforming for enhanced GPS signal reception and jamming immunity.
DIGAR’s advanced GPS capabilities can work with intelligence, surveillance, reconnaissance, and unmanned aerial vehicles, according to BAE Systems.
The F-15 Eagle is the second fighter aircraft to receive DIGAR upgrades, following the F-16 Fighting Falcon.
Jamming Protection Upgrade
In June, BAE Systems expanded its DIGAR beamforming capabilities by incorporating Trimble receivers in addition to its own receivers.
“The modern battlespace has evolved, and peer state positioning, navigation, and timing threat systems are challenging our ability to conduct combat operations in the place and manner of our choosing,” Wild explained.
Through the update, the system has increased its GPS jamming protection by “a million-fold,” according to the firm.
Electronic Warfare for Strike Eagles
Earlier this month, BAE Systems received a contract from Boeing to supply an electronic warfare system for US F-15E and F-15EX Strike Eagle fighters.
The contract included BAE’s EPAWSS (Eagle Passive Active Warning Survivability Systems), which will increase the aircraft’s situational awareness.
