The US Defense Logistics Agency (DLA) has awarded a $316m contract to BAE Systems to provide advanced military code (M-code) global positioning system (GPS) modules.

The latest award, which raises the total contracted amount to $641m, will ensure the availability of CGM for advanced military GPS receivers with capabilities such as ‘anti-jamming and anti-spoofing’.

As part of the contract, the company will produce CGMs for future ground, airborne, and weapon GPS receivers for the US DoD and its allied partners.

This announcement follows a $325m contract awarded to BAE by the DLA in May this year. This contract is for the delivery of modernised GPS user equipment (MGUE) increment one common GPS modules (CGMs) that are compatible with the advanced M-code signal.

BAE Systems Navigation and Sensor Systems business development director Frank Zane said: “Military operations require assured positioning, navigation, and timing and our customers are shifting to M-code to harden their GPS systems against jamming and spoofing.

“We’re ready to meet this need today with secure, reliable M-code GPS solutions, and we’re developing the next generation of solutions to stay ahead of the threat.”

The company is currently developing two advanced M-code GPS receivers, the miniature precision lightweight GPS receiver engine-M-code (MPE-M) and the NavStrike-M GPS receiver.

BAE said that the ultra-small MicroGRAM-M deliveries are expected next year while the strategic anti-jam beamforming receiver-M-code (SABR-M) deliveries are scheduled for 2024.
