Signal Acquisition and Tracking in the DOD Standard Miniaturized Airborne GPS Receiver

Jeff L. Kacirek and Redge G. Bartholomew

Abstract:	This paper presents the signal acquisition and tracking capabilities and performance of the DOD standard Miniaturized Airborne GPS Receiver (MAGR) produced by the Collins Avionics and Communications Division, Rockwell International. This includes a presentation of signal acquisition, tracking, and reacquisition strategies; a discussion of how these strategies are affected by the MAGR’s rapid acquisition and enhanced anti-jamming assets; a consideration of the effect on these strategies of handling multiple codes and frequencies, handling jamming, off-nominal signal strength, and spoofing (unclassified); and a presentation of satellite selection methods, data collection strategies, and signal delay determination and calibration methods. Performance data - captured during the government’s qualification tests - is included, identifying acquisition and reacquisition speeds, and tracking reliability statistics under both benign as well as worst case conditions.
