[Avionics Today 06-22-2015] GPS Source and Rockwell Collins have successfully demonstrated the ability of the Military-Code Ground-Based GPS Receiver Application Module (GB-GRAM-M) receiver card to fit within the Defense Advanced GPS Receiver (DAGR) Distributed Device (D3). The companies claim to be the first to provide this capability for the M-code signal, which is a main element in the modernization of military GPS capabilities.
GPS Source’s D3 supports new or retrofit programs integrating radio or communications equipment. It removes the burden of multiple Selective Availability Anti-Spoofing Module (SAASM) GPS receivers or antennas. As a SAASM GPS router, it is designed to meet the U.S. Army’s D3 performance requirements, mounted into an existing DAGR vehicle mount
The initial fit checks confirm that the Rockwell Collins GB-GRAM-M Type II receiver fits within the volume of the D3 and is able to acquire, track and navigate using C/A, Y and M-code while enclosed in the unit. Initial testing also validated backwards compatibility of the IS-GPS-153 serial port interface of the GB-GRAM-M receiver.
“This demonstration paves the way for the D3 to incorporate the next-generation GPS capability that our GB-GRAM-M provides,” said Mike Jones, vice president and general manager of communication and navigation products for Rockwell Collins.
