Symmetricom announces its XLi SAASM Time and Frequency Receiver with a new Ground-Based GPS Receiver Application Module (GB-GRAM) SAASM receiver has been granted security approval by the Global Positioning Systems Wing (GPSW), meeting the latest security requirements of the Department of Defense. The GB-GRAM GPS Receiver is integrated into Symmetricom’s XLi SAASM, an ultra precision time and frequency instrument.

The U.S. Government’s GB-GRAM program fulfills a GPS Wing initiative to migrate to a defined, open system architecture for ground-based embedded military applications, incorporates the SAASM security device and is a low-power, secure and jam resistant standardized GPS solution used in communications and weapons platforms across the military. Formerly the Joint Program Office, GPSW has the overall responsibility for controlling the development, production, sale and distribution of GPS SAASM PPS Host Application Equipment.

The XLi SAASM’s GB-GRAM GPS Receiver is a Small Serial Interface form factor, lightweight, third-generation GPS PPS, 12-channel receiver supporting Direct Y and Black keys. Initially security approved by GPSW in 2005, the XLi SAASM is based on Symmetricom’s XLi Time & Frequency System, the most precise, versatile and flexible solution for high performance timing and synchronization requirements. SAASM is the security architecture selected by the Joint Chiefs of Staff to provide the next generation security functions for GPS authorized military users. Taking into account the JCS mandate that went into effect in October 1, 2006 requiring all newly fielded DoD GPS systems to use SAASM compliant PPS devices, unless waivered, the XLi SAASM provides the highest immunity to jamming plus multiple options that enable military users to tailor their systems to support nearly every possible output/input needed for time and frequency applications.
