BAE to Develop Next Generation M-Code GPS for US Forces

BAE Systems received a $247 million contract from the U.S. Space Force’s Space and Missile Systems Center to design and manufacture an advanced military GPS receiver and next-generation semiconductor. The technology will provide positioning, navigation, and timing (PNT) capabilities to warfighters so they can execute missions in challenging electromagnetic environments.

The Military GPS User Equipment Increment 2 Miniature Serial Interface program will provide improved capabilities for size-constrained and power-constrained military GPS applications, including precision-guided munitions and battery-powered handheld devices. The program will focus on the certification of an advanced application-specific integrated circuit (ASIC) and the development of an ultra-small, low-power GPS module. Both products will work with the next-generation military M-Code signal technology, which provides reliable GPS data with anti-jamming and anti-spoofing capabilities to protect against electronic warfare threats.

“This program enables us to further develop our core M-Code technology to deliver high-performance, next-generation GPS capabilities,” said Greg Wild, director of Navigation and Sensor Systems at BAE Systems. “Our M-Code receiver and next-gen ASIC will enable secure and reliable military GPS capabilities in a broader range of platforms.”

M-code is a new military signal used in the L1 (1575.42 MHz) and L2 (1227.60 MHz) GPS bands. It is designed to improve security and anti-jamming properties of military navigation using GPS.

M-Code offers several operational benefits:

Jamming Resistance: M-code signals can be delivered to specific regions using spot beam transmissions from GPS Block III satellites. The high-gain directional antenna on the satellites aims the M-code signal at a specific region of the earth, with much greater satellite power in that region. The transmitted signals are expected to be around 20-dB more powerful than the conventional full-Earth coverage beam.

Blue Force Electronic Attack Compatibility: Blue Force Tracking provides the US military to with location information about friendly forces. The M-code signal because of its modulation type, allows to selectively jam the commercial GPS L1 C/A signal (C/A code) and continue receiving the M-Code signal from friendly military forces. This practice is called “blue force jamming” or “blue on blue jamming”.

Anti-Spoof: The M-Code signals are encrypted and their receivers are able to detect and reject false signals.

BAE Systems’ Precision Strike business has 45 years of military GPS experience and more than 1.5 million GPS devices on over 280 platforms around the world. The company is currently producing M-Code GPS receivers in multiple form factors, including the lowest power, smallest form factor M-Code solution available on the market today. Additional prototypes are in development for ground, weapons, and airborne mission applications, and the company’s M-Code GPS products are available to U.S. allies via Foreign Military Sales.
