Air-To-Air Missile Tracking Concepts Using Translated GPS

Sultan Mahmood, Steve Sovaiko

Abstract:	The concept of tracking over-the-horizon (OTH) Air-to-Air Missiles (AAM's) using translated GPS is explored in this paper. The Airborne Platform/Telemetry Relay System (AP /TM) is used to receive the S-hand translated GPS signals from the AAM, frequency translate to L-band and retransmit to a ground-based Translator Processing System (TPS). A miniaturized strapdown IMU is proposed to be used in the AAM and its output is downlinked on the translator pilot carrier. The issues of using the IMU signal for aiding the translator signals in the TPS are addressed. The measurement set itself consists of pseudo-range sums and pseudo­range rate sums for the three links between the GPS satellites and the TPS. The signal processing for the pseudo-range rate sum to eliminate the oscillator errors in the L-band to S-hand translator and the S-hand to L-band translator are analyzed. The extended range coverage due to the use of the AP/TM is quantitatively analyzed along with the issue of GPS SV common visibility.
