Supporting both NAVWAR and Global Air Traffic Management (GATM) requirements, the Collins Airborne SAASM Receiver (ASR) is a 12-channel, all-in-view, dual frequency, GPS receiver. ASR incorporates Rockwell Collins’ third generation of Selective Availability Anti-Spoofing Module (SAASM) and is designed in accordance with the GPS "Receiver Application Module Guidelines" (GRAM-S). Specifically designed to meet small package requirements, the ASR provides GRAM-S performance in less than half the volume of a SEM-E receiver.

Building upon the GPS Embedded Module (GEM) legacy begun in 1990, the ASR incorporates numerous advanced features. All-in-view satellite tracking for optimized geometry and satellite drop-out immunity. Fault Detection and Exclusion (FDE) per DO-229 providing navigation solution integrity. Switchable SPS/PPS function to facilitate civil airspace interoperability. Carrier phase measurement outputs enabling precision navigation solutions.

To resist the effects of jamming, the ASR incorporates field proven techniques used on all Rockwell Collins receivers including advanced software algorithms, dual frequency (L1/L2) operations, fast direct-Y acquisition, and inertial aiding.

The ASR flexible I/O supports open systems architectures. Industry standard interfaces include RS-422 (serial) in accordance with ICD-GPS-155, plus a RS-422 instrumentation port, a RS-232 PLGR Hot Start, and various discrete signals. Antenna interfaces support AE-1, GAS-1, and both active and passive FRPA installations.

Functions and features are continually added to an already vast list of capabilities and user configurable software options. For a complete list of GEM functions and features contact your local Rockwell Collins representative.

Continuing the Rockwell Collins tradition of unsurpassed performance in GPS receivers, the ASR offers big performance in a small package.
