The $13m contract will see the company integrate its digital GPS anti-jam receiver onto the F-15E aircraft.
Once equipped, the DIGAR technology will protect the fighter aircraft from evolving adversaries that jam the GPS signals.
BAE Systems navigation and sensor systems product line director Greg Wild said: “Modern airborne missions require accurate positioning and navigation data, and GPS systems must be able to withstand adversaries’ best disruption efforts.
“Our DIGAR antenna electronics are trusted to protect these platforms in contested environments.”
Associated work will be carried out at the company’s facility in Cedar Rapids, Iowa, US.
The F-15 Strike Eagle is the USAF’s second fighter jet to receive DIGAR GPS upgrades.
A part of BAE Systems’ family of military GPS products, DIGAR allows the fighter jets to undertake missions in rough signal environments by providing reliable military GPS systems.
According to the company, DIGAR uses high-performance signal processing and advanced antenna electronics to ensure better GPS signal reception.
In June, the company also expanded this DIGAR technology by adding new beamforming capabilities, which is a combination of 16 steered beams that provide immunity against signal jamming.
All such capabilities together allow the fighter aircraft to conduct manoeuvres in highly contested battlespace.
Apart from aircraft, the company claims that its GPS products can also be used with intelligence, surveillance and reconnaissance aircraft, uncrewed aerial vehicles, handheld electronics, precision-guided munitions and other vehicles.
