Trimble has been authorised to go ahead with production of its Selective Availability Anti-Spoofing Module (SAASM) for incorporation into military Global Positioning System (G PS) receivers. SAASM represents the next generation of GPS security devices mandated for use in all military receivers fielded after October 1, 2002.
The SAASM is incorporated into Trimble's GPS Receiver Application Module (GRAM) technology for airborne, surface mobility, precision guided munitions and handheld receivers. It will also be retrofitted into Trimble's existing military receivers.
Trimble's SAASM will provide the highest level of GPS navigation accuracy, integrity, and protection to the US military and its authorised allies. The technology will also be available for license and integration into applications that require the SAASM-based GPS chipset for embedded designs.
In September of 1998, Trimble was awarded a contract from the NAVSTAR GPS JPO to research and develop next generation military GPS technology. The company has been involved with SAASM efforts since its inception in 1992. It was Trimble's receiver and software that provided the test bed for the Key Data Processor, the heart of the security upgrade.
