2022年8月20日 · 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) signal transmitted by the GPS constellation.

2000年3月16日 · Rockwell Collins has leveraged its position as a primary military Global Positioning System (GPS) supplier by developing a new, low cost version of the Selective Availability Anti-Spoofing Module (SAASM) for use in multiple applications.

2019年8月22日 · SAASM is an enhanced GPS security architecture designed to provide over-the-air rekeying of GPS receivers in order to encrypt and decrypt the GPS signal. M-code will provide anti-jam capabilities.

er. 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 recei.

Top SAASM-Based GPS and INS Integration Challenges ehicle 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, succe

The U.S. Department of Defense has mandated the use of selective availability anti-spoofing module (SAASM) GPS in all programs of record. With the Rockwell Collins RTK SAASM technology solution, unmanned aircraft systems can now achieve centimeter-level relative navigation accuracy for autonomous capture, landing or other operations, while ...

By purchasing a SAASM receiver now, authorized users comply with the DoD GPS security architecture and possess the most secure GPS technology to enhance their ability to use precise posi-tioning, velocity, and time in all environ-ments.

The SAASM HD GPSDO product line combines for the first time a P (Y) capable military SAASM dual-frequency GPS receiver with a chip-scale atomic clock on a ruggedized PC board with dimensions of only 2.0 x 2.85 x 0.6 inches. CSAC or DOCXO oscillators offer three variants for timing or Low Phase Noise frequency applications.
