BAE Systems will provide Eurofighter GPS signal jamming protection

BAE Systems’ Digital GPS Anti-jam Receiver [DIGAR] has advanced to the next stage of the Phase 4 Enhancements [P4E] program after successfully proving both functional compatibility and installation feasibility in the Eurofighter Typhoon aircraft.

This vital development means that the aircraft’s strength against GPS signal jamming, spoofing, and Radio Frequency [RF] interference will be significantly improved. As a result, pilots will have greater confidence in executing their missions even in the most RF-intensive environments. 


DIGAR, deploying sophisticated antenna electronics, advanced signal processing, and digital beamforming, boosts GPS signal reception and provides a superior shield against jamming. This high level of protection from GPS jamming is imperative for combat aircraft navigating through a confrontational battlespace. 

The fighter will also benefit from BAE Systems’ new GEMVII-6 airborne digital GPS receiver. This, when paired with the DIGAR antenna electronics unit, facilitates exceptional digital beamforming anti-jamming capabilities. 

“Accurate positioning and navigation data are essential for modern fighters to achieve mission success in GPS-contested environments”, says Luke Bishop, director of Navigation and Sensor Systems at BAE Systems. “Our DIGAR and GEM VII GPS receivers are designed to support and safeguard these crucial platforms in GPS-challenged fields.”

The UK’s key pillar

The Eurofighter Typhoon serves as a key pillar of air defense for the UK as well as several of its crucial European and international allies. It is operational 24/7, year-round, and provides air security even in front-line operations, including ongoing NATO air policing across Eastern Europe. 

As part of the four-nation Eurofighter consortium behind the aircraft, BAE Systems is dedicated to continually enhancing the Typhoon jet to sustain its cutting-edge military capability. 

Apart from the Typhoon, DIGAR is also installed on the F-16, F-15, and other special-purpose U.S. aircraft like air interdiction and force protection platforms, intelligence, surveillance, reconnaissance aircraft, and unmanned aerial vehicles. 

BAE’s GPS products

Boasting more than four decades of GPS experience, the versatile suite of BAE Systems’ GPS products has been designed considering size, weight, and power characteristics, making them suitable for various applications including handheld electronics, precision-guided munitions, unmanned aerial vehicles, and other vehicles and aircraft. 

BAE Systems’ facility in Cedar Rapids, Iowa, where investment has been made in a state-of-the-art 278,000-square-foot engineering and production center, has been dedicated to the work on DIGAR and GEMVII.
