Missions and lives depend on warfighters’ ability to find their way in unfamiliar and unpredictable territory. A new GPS receiver receives the new M-code military GPS signals resistant to jamming and spoofing. 

M-code is GPS signals for use by the military. It is designed to enhance PNT capabilities and improved resistance to existing and emerging threats to GPS, such as jamming and spoofing.

BAE Systems has unveiled its ultra-small MicroGRAM-M GPS receiver. The device, which is lightweight and as small as a postage stamp, is a power-efficient M-code embedded GPS receiver, capable of delivering assured positioning, navigation and timing (PNT) for size-constrained and other micro-applications.

It is designed for various uses, from soldiers’ handheld devices to small unmanned aerial vehicles, providing them with a solution that’s resistant to adversaries’ disruption efforts in highly contested environments.

The receiver features rapid, secure GPS signal acquisition, enhanced security and resiliency, anti-jamming and anti-spoofing capabilities, and very low power consumption for an M-code device. 

Its physical dimensions resemble those of its predecessor, enabling quick upgradability to M-code and reduced system integration costs. 

It is a proven, tamper-proof M-code Common GPS Module that encapsulates classified data and signal processing.

Its qualification is underway, with full-rate production expected in 2022, as reported by
