Raytheon M-code receiver deployment underway

In 2019, the U.S. Air Force certified the security architecture of Raytheon Intelligence & Space’s M-code modules and receivers as providers of secure and reliable access to modernized GPS. The resilient receivers are designed for high anti-jam performance.

Raytheon’s M-code application-specific integrated circuit (ASIC) chip is either integrated into a ground-based receiver card optimized for low dynamic applications, or used as an avionics/naval receiver card to support multiple end users.

“Our focus is on taking a comprehensive approach to resilient navigation,” explained Chad Pillsbury, director for Raytheon’s Secure Sensor Solutions. “We provide the complete family of PNT solutions. We start with the fundamental components, like the ASIC chip, and tailor our solution for the platform and mission requirements.”

Open Architecture. Raytheon successfully completed testing of the first M-code receiver onboard the U.S. Air Force’s B-2 bomber in 2017. “Since then, we’ve undergone a number of tests internally and with third-parties. Our M-code receivers have standard interfaces and open architecture protocols, enabling them to work with both U.S. and allied systems. By pairing our M-code receiver with our anti-jam electronics and antenna, our systems enable warfighters to combat the most advanced threats seen in the world today,” Pilsbury said.

The receiver is planned to be incorporated into many fighters, bombers and weapons systems across the U.S. Department of Defense. “We provide enhanced anti-jam, anti-spoof GPS capabilities, as well as alternate navigation and multi-constellation support that represent a significant improvement over the systems currently used by today’s warfighters,” Pillsbury said.

Meeting Advancing Threats. “The hardest part is meeting a changing threat target,” Pillsbury explained. “The fact is the threat is advancing at a rapid rate. Because of that, challenges are constantly evolving.

“That means we had to design solutions that were simultaneously robust and secure, but also flexible and open so we can continually upgrade them. That’s not an easy thing to do.

“But, by taking a comprehensive approach that looked at the whole problem rather than just part of it, we’ve developed systems that address these challenges and have the flexibility to address future challenges.”

Raytheon’s M-code products are now available to the U.S. military and its allies in accordance with International Traffic in Arms Regulations and the U.S. State Department.
