Research of Conducted Susceptibility Testing Method for Inter-modulation & Cross-Modulation of GPS Receiver

GPS satellite positioning technology has been applied in aviation and spaceflight.By describing the working principle of the GPS receiver and the characteristic of GPS signal,we analyzed the inter-modulation and cross-modulation conducted susceptibility of testing principle of the receiver and developed the experimental technique for GPS receiver inter-modulation and cross-modulation conducted susceptibility.This testing method is faster and easier and convenient for obtaining the parameter of inter-modulation and cross-modulation bate-ratio of the receiver.
