Abstract

GPS provides a high degree of precision at affordable cost for weapons guidance systems, but has inherent susceptibility to jamming and interference. This program applies ERI's interference suppression technology to GPS antijam requirements for small precision guided missiles and munitions (PGM). The program develops a rugged, small, low-cost interference suppression capability for PGM GPS using a combination of new and repackaged ERI ISU technology. The program transfers current design concepts to a rugged L1/L2 P-code RF antijam system electronics module for PGM flight test demonstration, and develops critical areas of the system to meet size and temperature objectives. The solution will suppress and track jamming with rapid convergence times compatible with the high dynamics of PGMs, and provide an effective cost/performance solution to protect GPS receivers using a single GPS dual-port aperture. Phase 2 designs, builds and tests a flight worthy, prototype, PGM antijam system that will meet protection performance and environment requirements.
