Abstract: Based on the anti-interference ability of Beidou satellite navigation system, the system test, frequency analysis and simulation generation of the interference signals that may occur in the satellite navigation system are carried out, and the modules of single frequency continuous wave, linear frequency modulation, BPSK modulation, frequency agility, pulse modulation and combined interference signals are analyzed, and finally the software design process of interference signal simulation source is put forward.

Keywords: interference simulation source; mixed interference; multi-system; satellite navigation
