Abstract: After analyzing the performance of the Beidou receiver in complex jamming environment,it provides a specialized theoretical basis for anti-jamming.Though the analysis of satellite navigation direct sequence spread spectrum communication system model,this paper analysed and compared the BER performance and the equivalent load ratio of Beidou satellite navigation system under two common interference,and it also carried out the digital simulation with Matlab.The simulation results show that narrowband interference has greater impacts on the receiver than the band interference.And the navigation signal is reduced on performance level,interference signal bandwidth and position disturbance implementation.So the performance improvement of navigation signal needs to consider a variety of factors mentioned above.

Key words: Beidou satellite,Navigation system,Interference signal,Bit error rate,Signal to noise ratio
