Due to the problem of the lack of evaluation method for GPS optimal jamming signal,the method of judging the optimal jamming signal by using error rate is proposed. A satellite navigation receiver model is established through the research on the working principle of the satellite navigation receiver,and a bit error rate model based on the intermediate frequency signal is established via the research on the processing of navigation signal by the different modules of the receiver. The error rate of the receiver under different interference conditions is studied take the advantage of the simulation of different interference signals using simulation tools. The relationship curve between the error rate and the ISR(InterferenceSignal Ratio) is obtained by changing the power of the interference signal. Then the optimal jamming signal is obtained by comparing the error rate under the different interference signals in the same ISR. Through the experimental verification,under the circumstances of the same interference signal power,the PN related code signal effect is optimal when in the receiver ISR range ,which provides a basis for the development and design of the satellite navigation signal jamming equipment.
