Abstract: Addressing the problem that GPS receiver has no way to work regularly for the high revolution projectiles, the change of GPS singnals frequency and phase in condition of advanced spinning is calculated and analyzed to provide a basis for designing baseband algorithm of GPS receiver. The mathematical moderation is built up according to the features of spinning projectiles movement and the GPS signals propagation and the Doppler frequency shift and phase of received signal calculated. The result showed that the signals maximum Doppler frequency is 300Hz and the shift phase is 0.6π when the revolution is 200 rounds per second, but the code signals have little change. These can be referenced for the design of GPS signals capturing and tracking algorithm under advanced spinning.
