The MPE-S Type II is smaller and lighter than its predecessor MPE-S, yet retains all functionality and is fully backward compatible. MPE-S Type II is based on the Collins Aerospace Selective Availability/Anti-Spoofing Module (SAASM), which encapsulates all classified data and signal processing into one tamper-proof module, increasing the security of the MPE-S Type II. SAASM also provides jamming and spoofing protection for US and allied forces operating in hostile environments. The MPE-S is the US Army Standard Embedded GPS Receiver for the Ground-Based GPS Receiver Application Module (GB-GRAM) program. It is intended for use in multiple DoD, federal civilian and foreign military sales platforms requiring real-time precise GPS data. The small size and features of the GB-GRAM standard make it attractive for Command, Control, Computers, Communication and Information (C4I) equipment, vehicles and other system platforms seeking to integrate a robust secure GPS capability.
