Trimble has announced that it has been awarded a $2.1 million military development contract to supply Global Positioning System (GPS) technology for Raytheon Company’s Miniature Airborne GPS Receiver (MAGR) 2000 GRAM SAASM (M2KGS) Program.
Under the contract, Trimble will incorporate its Selective Availability Anti-Spoofing Module (SAASM) technology in the ForceTM 5 GPS Receiver Application Module (GRAM-S) for use in Raytheon’s MAGR 2000.
Trimble’s Force 5 GRAM-S is an embedded, dual-frequency GPS receiver module with Precise Positioning Service (PPS) capability. Designed in compliance with the NAVSTAR GPS Joint Program Office (GPS JPO) GRAM guidelines, the Force 5 provides unequaled performance for airborne and high dynamics applications. Raytheon’s MAGR 2000, utilizing the Force 5, has been selected for use in a variety of U.S. and Allied military aircraft including the MH-53E Sea Dragon, F-16 Fighting Falcon, F/A-18 Hornet, AV-8B Harrier, ASTOR and E-2C Hawkeye.
SAASM is the architecture selected by the Joint Chiefs of Staff, which implements the next generation security functions for all GPS PPS military users. The use of SAASM significantly enhances and ensures the U.S. and Allied military user the ability to obtain precise GPS position, velocity, time, and other GPS sensor information in all types of environments. Trimble’s SAASM technology was granted GPS JPO security approval on May 1, 2000.
Like the current Force 5, the SAASM-equipped GRAM-S will provide the features necessary for Instrument Flight Rules (IFR) operation including all-in-view tracking, Fault Detection and Exclusion (FDE) and step detector in accordance with RTCA/DO-229, predictive FDE in accordance with FAA Notice 8110.60, and European B-RNAV aircraft operations. When operated in the PPS mode, it will also provide Navigation Warfare (NAVWAR) features including Anti-Spoofing and high Anti-Jamming protection including integration with Controlled Reception Pattern Antennas.
