M-Code GPS receiver from GPS Source works in DAGR Distributed Device from Rockwell Collins

LOS ANGELES AIR FORCE BASE, Calif. Engineers at Rockwell Collins and Rockwell Collins demonstrated the ability of the Military-Code Ground-Based GPS Receiver Application Module (GB-GRAM-M) receiver card to work within the Defense Advanced GPS Receiver (DAGR) Distributed Device (D3).

The companies are the first to provide this capability for the M-code signal, a key part in the modernization of military capabilities. The initial fit checks assure that the GB-GRAM-M Type II receiver fits within the volume of the D3 and can acquire, track, and navigate using C/A, Y, and M-code while enclosed in the unit. Initial testing also validated the backwards compatibility of the IS-GPS-153 serial port interface of the GB-GRAM-M receiver.

GPS Source’s D3 works with new or retrofit programs integrating radio or communications equipment. It mitigates the burden of multiple GPS receivers or antennas. As a Selective Availability Anti-Spoofing Module (SAASM) GPS router, it is designed to meet the Army’s Distributed Device (D3) performance requirements, mounted into an existing DAGR vehicle mount, using standard DAGR accessories.

The Rockwell Collins GB-GRAM-M is the result of one of the MUE card development contracts, awarded by the U.S. Air Force Space and Missile Systems Center. The MUE program is developing the next generation of GPS user equipment to have a new military signal and enhanced security architecture.
