BAE Systems Unveils microGRAM-M

World’s Smallest M-Code GPS Receiver

The postage stamp-sized MicroGRAM-M GPS receiver, unveiled by BAE Systems on 25 August, is the world’s smallest, lightest, and most power-efficient M-Code embedded GPS receiver, according to the company. It delivers 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,” explained Greg Wild, Director of Navigation and Sensor Systems. “MicroGRAM-M provides our armed forces and allies with a low-SWAP[size, weight and power consumption] 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 resilience, anti-jamming and anti-spoofing capabilities, and the industry’s lowest power consumption for an M-Code device. The 1×1.25×0.275in device 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.

MicroGRAM-M is the latest BAE Systems M-Code military GPS product, joining MPE-M and NavStrike-M, which deliver enhanced awareness in highly contested environments and precision munitions guidance,” said John Watkins, VP/GM of Precision Strike & Sensing Solutions at BAE Systems. “Qualification of MicroGRAM-M is underway, with full-rate production expected in 2022.”
