A Robust Anti-Jamming Navigation Receiver with Antenna Array and GPS/SINS

Abstract

In this letter, a novel robust scheme with antenna array and global positioning system/strapdown inertial navigation system (GPS/SINS) is proposed for improving the anti-jamming capability of navigation receiver. The key idea is that the apriori knowledge for beamforming is supplied by satellite almanac and tightly coupled GPS/SINS. Then a multiple constrained minimum variance-spatial temporal adaptive processing (MCMV-STAP) beamforming algorithm is proposed for enhancing satellite signals and suppressing interferences. Finally, desired satellite signals without interferences are used to calculate satellite pseudoranges, which are introduced to the coupled GPS/SINS filter. Simulation results show that the anti-jamming capability of the proposed scheme is reliable and robust.
