BAE Systems has unveiled its ultra-small MicroGRAM-M global positioning system (GPS) receiver for armed forces.

MicroGRAM-M is compatible with M-Code military GPS signals that are resistant to jamming and spoofing. The armed forces can use this GPS receiver to add positioning, navigation, and timing (PNT) capabilities in size-constrained and other micro-applications.

The device is about the size of a postage stamp but has the same physical dimensions as its predecessor to enable quick upgrades for existing applications.

BAE Systems Navigation and Sensor Systems director Greg Wild said: “We’re delivering reliable PNT where our customers need it – from soldiers’ handheld devices to small unmanned aerial vehicles.

“MicroGRAM-M provides our armed forces and allies with a low-SWAP M-Code GPS solution that’s resistant to adversaries’ disruption efforts in highly contested environments.”

According to the company, the device features rapid secure GPS signal acquisition, enhanced security and resiliency, anti-jamming and anti-spoofing capabilities. It also consumes less power compared to other such M-Code devices.

BAE Systems Precision Strike & Sensing Solutions vice-president and general manager John Watkins said: “MicroGRAM-M is the latest BAE Systems M-Code military GPS product, joining MPETM-M and NavStrikeTM-M, which deliver enhanced awareness in highly contested environments and precision munitions guidance.

“Qualification of MicroGRAM-M is underway, with full-rate production expected in 2022.”

Earlier this month, BAE Systems signed a strategic business agreement to develop next-generation defence applications using Intel’s technology.

The agreement provides BAE Systems’ FAST Labs research and development (R&D) organisation with early access to select Intel technologies.
