BAE Systems to enhance GPS technology on Eurofighter Typhoon.

After successfully demonstrating its functional compatibility and physical installation feasibility, BAE Systems Digital GPS Anti-jam Receiver (DIGAR) has been chosen to advance to the next phase of the Phase 4 Enhancements (P4E) capability program for the Eurofighter Typhoon aircraft. DIGAR will enhance the aircraft's protection against GPS signal jamming, spoofing, and Radio Frequency (RF) interference, enabling pilots to carry out their missions even in heavily contested RF environments.

In addition to the Typhoon, BAE Systems' Digital GPS Anti-jam Receiver (DIGAR) is also integrated into other aircraft such as the F-16, F-15, and various specialized platforms in the U.S., including air interdiction and force protection aircraft, intelligence, surveillance, and reconnaissance aircraft, as well as unmanned aerial vehicles (Picture source: BAE Systems)

DIGAR utilizes advanced antenna electronics, high-performance signal processing, and digital beamforming to significantly improve GPS signal reception and enhance resistance to jamming. These capabilities substantially elevate the level of GPS jamming protection, a critical requirement for combat aircraft operating in contested battlespaces.

Furthermore, the fighter aircraft will be equipped with BAE Systems' new GEMVII-6 airborne digital GPS receiver, which, when paired with the DIGAR antenna electronics unit, empowers the platform with high-capacity digital beamforming anti-jamming capabilities.

Luke Bishop, director of Navigation and Sensor Systems at BAE Systems, emphasized the importance of accurate positioning and navigation data for modern fighters operating in GPS-challenged environments, stating, "Our DIGAR antenna electronics and GEM VII GPS receivers are trusted to protect these vital platforms in GPS challenged environments to support mission success."

The Eurofighter Typhoon serves as a cornerstone of combat air defense for the UK and several key European and international allies. It is operational in nine nations and provides round-the-clock air security, including ongoing NATO air policing efforts in Eastern Europe. BAE Systems, a key member of the four-nation Eurofighter consortium, continually invests in enhancing the Typhoon jet's military capabilities to maintain its cutting-edge performance.

In addition to the Typhoon, DIGAR is also integrated into other aircraft such as the F-16, F-15, and various specialized platforms in the U.S., including air interdiction and force protection aircraft, intelligence, surveillance, and reconnaissance aircraft, as well as unmanned aerial vehicles.

Leveraging over four decades of GPS expertise, BAE Systems' range of GPS products offers size, weight, and power characteristics suitable for a wide array of applications, including handheld electronics, precision-guided munitions, unmanned aerial vehicles, vehicles, and aircraft.

The development and production of DIGAR and GEMVII occur at BAE Systems' cutting-edge facility in Cedar Rapids, Iowa, spanning an impressive 278,000 square feet, showcasing the company's commitment to advancing GPS technology.
