    BAE Systems provides enhanced GPS technology for F-15 Eagle fighters

    BAE Systems has received a $13 million contract for advanced GPS technology to protect U.S. F-15E aircraft from GPS signal jamming and spoofing. The company’s Digital GPS Anti-jam Receiver (DIGAR) will ensure the reliability of military GPS systems for aircraft operating in challenging signal environments.

    DIGAR uses advanced antenna electronics, high-performance signal-processing and digital beamforming — a capability that combines 16 steered beams — for better GPS signal reception and superior jamming immunity. These capabilities are critical for high-speed aircraft as they maneuver through the battlespace.

    The F-15 Eagle is the second U.S. Air Force fighter platform to receive DIGAR GPS upgrades, following the F-16 Fighting Falcon. DIGAR 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, Navigation and Sensor Systems product line director at BAE Systems. “Our DIGAR antenna electronics are trusted to protect these platforms in contested environments.”

    BAE Systems’ family of military GPS products offer size, weight and power characteristics suitable for a variety of applications, including handheld electronics, vehicles, unmanned aerial vehicles, aircraft and precision-guided munitions. In addition to GPS anti-jam products, the company is delivering advanced GPS products compatible with the next-generation M-code satellite signal, and is developing the next generation of receivers to ensure dependable GPS for warfighters across land, air and sea domains.

    BAE Systems work on military GPS technology takes place in Cedar Rapids, where the company is investing more than $100 million to build a 278,000-square-foot, state-of-the-art research and manufacturing center.

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

    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, Iowa, developed software to ensure the compatibility of its antenna electronics with industry-standard embedded GPS inertial navigation system (GPS/INS) technology, enabling fast communication with transmitter electronics for superior beamforming.


    BAE Systems is exhibiting at the ION Joint Navigation Conference, which takes place June 6-9 in San Diego.


    DIGAR beamforms with both BAE Systems receivers and Trimble GPS receivers embedded in aircraft GPS/INS, 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.”

    DIGAR is a high-performance military GPS-based system for fixed-wing, rotary-wing and unmanned airborne 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 the warfighters who rely on it.

    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. The company’s military GPS business is based in Cedar Rapids, Iowa, where it is building a 278,000-square-foot state-of-the-art research and manufacturing facility scheduled to open this year.
