摘　　要：In order to improve the dynamic perfor-mance of the Global navigation satellite system （GNSS） receiver, we propose a novel Doppler-parameter detection algorithm using short-term cyclic iteration. The algorithm is capable of calculating the initial Doppler shift, the shift velocity and acceleration from only four consecutive phase errors. Then we present a new carrier tracking loop based on the algorithm, and discuss the issues involving the noise suppression and the feedback control. Simulation results demonstrate that the proposed loop can effectively detect the high-order Doppler shift transition and stably track the signals in the dynamic environment.
