Abstract: Anti-jamming compatible type satellite navigation receiver can use the combination of satellite positioning systems to perform high-precision positioning, and also has an excellent anti-interference performance by the application of adaptive null steering antenna. The hardware circuit of the system is introduced, and the hardware platform is adopted by the power inversion algorithm for interference suppression. Simulation results show that the adaptive null steering antenna can effectively improve the SNR of the received signal, and can expand the application range of compatible type satellite navigation receiver.

Key words: BD/GPS/GLONASS compatible receiver, adaptive null steering antenna, power inversion, satellite navigating and positioning
