A Selective Availability Anti-spoofing Module (SAASM) is used by military Global Positioning System receivers to allow decryption of precision GPS observations, while the accuracy of civilian GPS receivers may be reduced by the United States military through Selective Availability (SA) and anti-spoofing (AS). [1]

Aug 22, 2019 · The Air Force upgraded the GPS Control Segment to AEP Version 5.6 to provide Contingency Recovery and Over-the-Air Rekeying of military GPS receivers with Selective Availability/Anti-Spoof Module (SAASM).

Aug 20, 2022 · Selective Availability Anti-Spoofing Modules (SAASM) are GPS modules used by the United States military that has access to more precise and encrypted P (Y) code signals of the GPS constellation.

One of the existing anti-spoofing technologies is the Selective Availability Anti-Spoofing Module (SAASM) available for the GPS constellation. A SAASM-enabled GPS receiver allows an approved government or military user to access the encrypted P(Y) …

SAASM-based GPS into an INS for unmanned vehicle systems or manned portables such as target locators. From creating a robust, real-world algorithm to making micro-electromechanical parts fit while avoiding magnetic interference, successful integration begins with a knowledge of the challenges. 1 ACQUIRING RESTRICTED SAASM CIRCUIT BOARDS

The military community is in the midst of navigating a transition from selective-availability anti-spoofing module (SAASM) to modernized M-code encryption and adjusting to the major shift to international satellite constellations; the military is also on a quest for better methods to secure the Global Positioning System (GPS) from spoofing and ...

To combat this situation, the U.S. govern-ment launched a program in the 1990s referred to as SAASM. SAASM deploys anti-spoofing measures using cryptogra-phy to protect authorized users from false satellite signals generated by an enemy.

BAE Systems | Airborne SAASM Receiver (ASR) 3.7 Features • Wide Area Augmentation System (WAAS) capable allows for extremely accurate positioning • 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

the Rockwell 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).

What is the definition of SAASM? Stands for selective availability anti-spoofing module. SAASM is used by military GP receivers to allow decryption of precision GPS observations and to help eliminate tampered satellite signals.
