The Airborne SAASM Receiver (ASR) 3.7-DS from BAE Systems is an Airborne GPS Receiver for L1 and L2 bands. It has 96 channels (48 hardware channels per thread) and hosts individual civil and military receivers on a single ASR form factor board. This receiver has a Wide Area Augmentation System (WAAS) capability for extremely accurate positioning. It interfaces with BAE Systems' Digital GPS Anti-jam Receiver (DIGAR) to provide unmatched anti-jamming performance for warfighters who must operate in the most challenging environments. The receiver supports all-in-view satellite tracking for optimized geometry and satellite drop-out immunity and Fault Detection and Exclusion (FDE) per DO-229 providing navigation solution integrity.

The ASR 3.7-DS supports standalone (unaided) or integrated (aided) operation which provides the user with highly accurate positioning. It has a PLGR hot-start time of 5 seconds, a time accuracy PPS of less than 30 ns (RMS), and a position accuracy PPS of 5.6 m (RMS, horizontal). This receiver supports flexible I/O supports open systems architectures and industry-standard interfaces. It is available in a housing that measures 4.9 x 3.2 x 0.8 inches and consumes less than 0.2 W of power.
