[SatNews] L-3 Interstate Electronics Corp. (IEC) has delivered 31 prototype ground-based GPS receiver application module modernized (GB-GRAM-M) receivers designed and developed under the Modernized User Equipment (MUE) Receiver Card Development program.

The receivers demonstrate the critical technologies needed to incorporate a new Military-Code (M-Code) signal and common GPS module security architecture for enhanced integrity with improved anti-jam and anti-spoof capabilities. The L-3 GB-GRAM-M receivers process Precise Code, Course/Acquisition-Code, and M-Code signals. The delivery of GB-GRAM-M receivers completes L-3’s formal qualification testing and supports the government’s developmental test phase. In addition, L-3 IEC has conducted live satellite signal tracking of SVN 62, the first GPS IIF satellite. The live tracking of true M-Code signals and recent card deliveries represent a significant milestone in the GPS MUE Receiver Card Development program, designed to bring the next generation of GPS technology to military users.
