The U.S. Air Force has demonstrated successful operation of its next-generation Military-code GPS signal in a jamming environment using a Raytheon Company receiver. In a recent test, the Raytheon-built Miniaturized Airborne GPS Receiver 2000 (MAGR2K) maintained GPS satellite tracking and provided accurate navigation at jamming levels far exceeding technical requirements. The MAGR2K was integrated with the Raytheon Advanced Digital Antenna Production (ADAP) system and equipped with a specialized M-code receiver card.
M-code receivers are required to provide significantly improved position, navigation, and timing performance based on the advanced GPS satellite signal. As part of the semi-annual NAVFEST exercise at White Sands Missile Range, Raytheon showcased the ease with which its M-code receiver card integrated into the MAGR2K, leveraging all the advantages of the M-code signal.
This is the first time an M-code receiver card has been successfully tested in an avionics GPS receiver. The results provide the Air Force with a clear path forward for fielding M-code capable GPS receivers. The innovative MAGR2K design is backward and forward compatible which will enable easy and cost-effective upgrades to M-code technology for existing military aircraft without having to replace the entire GPS receiver.
