Raytheon Co. has been awarded a $7.6 M engineering and manufacturing development contract to supply anti-jam Global Positioning System (GPS) receivers to the Air Force’s C-130 Avionics Modernization Program (AMP).
Boeing Integrated Defense Systems selected the Raytheon digital anti-jam receiver (DAR) to provide C-130 airlift and special mission aircraft with robust and highly accurate navigation components. Under a follow-on production contract, 982 DAR systems at a cost of approximately $37.3 M may be required. Raytheon’s Space and Airborne Systems will adapt the DAR militarized GPS anti-jam sensor, originally developed for high performance fighters such as the F-35 Joint Strike Fighter, to the Boeing C-130 AMP architecture. Each DAR system will include a 24-channel selective availability anti-spoofing module (SAASM) receiver, digital anti-jam electronics and a multi-element antenna. “The DAR system gives the C-130 the ultimate in military GPS technology,” said James Hvizd, avionic technology manager for Raytheon’s Precision Guidance Systems business area. “By integrating a 24-channel GPS SAASM receiver and adaptive beam-steering anti-jam electronics into a single line replaceable unit, the DAR system is fully compatible with the existing GPS Antenna System-1 (GAS-1) antenna electronics.” The system includes provisions to incorporate emerging joint precision approach and landing system (JPALS) and GPS modernization requirements. And, by leveraging the common core technology from the JSF anti-jam GPS sensor, the DAR system provides a dramatic savings in production and life cycle costs compared to legacy GPS receivers and anti-jam electronics.
