BAE Systems Broadens Anti-Jam GPS Receiver Capabilities

BAE Systems expanded the capabilities of its Digital GPS Anti-Jam Receiver (DIGAR) by enabling beamforming with Trimble receivers in addition to its own receivers. 

DIGAR is a high-performance military GPS system for fixed-wing, rotary-wing, and unmanned aerial platforms. It combines field-proven antenna electronics, advanced signal-processing, and beamforming techniques to improve the reliability of positioning, navigation, and timing data in the presence of disruptive electromagnetic signals. DIGAR is also compatible with the advanced M-Code – delivering additional security to warfighters.

BAE Systems claims its DIGAR’s beamforming capabilities increase the level of GPS jamming protection for aircraft by a million-fold – helping pilots execute their missions in contested environments.

BAE Systems’ engineers in Cedar Rapids developed software to ensure the compatibility of its antenna electronics with industry-standard Embedded GPS Inertial Navigation System (EGI) technology, enabling fast communication with transmitter electronics for superior beamforming. 

The company claims its DIGAR provides the only antenna electronics on the market to beamform with both BAE Systems receivers and Trimble GPS receivers embedded in aircraft EGIs, as well as federated GPS systems and stand-alone GPS 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,” said Greg Wild, director of Navigation and Sensor Systems at BAE Systems. “By combining DIGAR’s beamforming with trusted inertial navigation system data, we offer the highest level of jamming protection available today.”

BAE Systems’ anti-jamming GPS technology has defeated powerful and sophisticated adversary threat systems in testing and combat, and is available for airborne, shipborne, and ground vehicle applications.
