BAE Systems Develops World’s Smallest M-Code Military GPS Receiver

BAE Systems recently unveiled its ultra-small MicroGRAM-M GPS receiver compatible with M-Code signals that are resistant to jamming and spoofing.

About the size of a postage stamp, MicroGRAM-M is the world’s smallest, lightest, and most power-efficient M-Code embedded GPS receiver – delivering assured positioning, navigation, and timing (PNT) for size-constrained and other micro-applications.

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

MicroGRAM-M features rapid secure GPS signal acquisition, enhanced security and resiliency, anti-jamming and anti-spoofing capabilities, and the industry’s lowest power consumption for an M-Code device. The 1.0” x 1.25” x 0.275” MicroGRAM-M has the same physical dimensions as its predecessor, enabling quick upgradability to M-Code and reduced system integration costs. At its core is a proven, tamper-proof M-Code Common GPS Module that encapsulates classified data and signal processing.

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