SAASM GPS Receiver Option
GPS is an indispensable tool for synchronizing military actions and other timing applications, thanks to the GPS system’s extremely accurate and wells-ynchronized atomic clocks. However, GPS transmissions are relatively low-power and vulnerable to jamming. They may also be spoofed, a hacking technique in which seemingly legitimate data is faked.
To counter these threats, the Joint Chiefs of Staff have chosen the Selective Availability Anti-Spoofing Module (SAASM) as the GPS security architecture. As of October 2006, all newly fielded Department of Defense (DoD) GPS systems must use SAASM-compliant Precise Positioning System (PPS) devices.
A secure GPS receiver is available for SAASM applications as is required under the 2003 Joint Chiefs of Staff Instruction: Master Positioning, Navigation, and Timing Plan (CJCSI 6130.01C: Enclosure E). Learn more about this DoD mandate by reading "Enclosure E" of the document.
