In this paper,GPS Receiver carrier tracking loop's bandwidth and tracking dynamic character were stuclied.First analysing the main parameters affecting dynamic performance of the GPS Receivers,including the white noise,Allan phase noise of oscillator,vibration phase noise of oscillator and stress of dynamic.Occording to the analysising and simulation of different order phase lock loop and frequency lock loop,discussed the bandwidth of GPS receiver's carrier tracking loop we giving out to optimizing the receiver's dynamic system.Finaly we know that,setting the 2-order phase lock loop bandwidth to 18 Hz assisted 3-order frequency lock loop bandwidth to 10 Hz,the GPS receiver can track dynamic signal under 10 g and 100 g/s.
