Test Results from a Digital P(Y) Code Beamsteering Receiver for Multipath Minimization

Alison Brown and Neil Gerein

Abstract:	When using a digital phased array, it is possible to leverage the adaptive spatial signal processing of the array to minimize the effect of multipath signals arriving from near-by reflective surfaces. NAVSYS has developed a digital phased array that can be used for adaptive spatial processing, the High-gain Advanced GPS Receiver (HAGR). Previous testing using the L1 C/A code have demonstrated the performance improvements possible using spatial processing to increase the accuracy of the code and carrier observations and also to minimize the effect of multipath errors. In this paper, we present test results taken from a P(Y) digital beam-steering GPS receiver, the P(Y) HAGR that demonstrates the performance improvements possible for military GPS User Equipment (UE) when using spatial processing to increase accuracy and also to minimize the effect of multipath from near-by reflective surfaces.
