Research on Anti-Spoofing and Detection Technology in Satellite Positioning Section

The detector performance depends on the clock accuracy and the model, the clock parameters estimation error will lead to a decline in the performance of the detectors. Therefore, in order to reach the detector achieves a set of performance, it need to adjust the receiver of the crystal quality. In this paper, the method of detecting the clock states of the satellite navigation receiver is used to detect the receiver. The clock state model of the receiver is established in the static and motion mode, and the time variation of the clock state is analyzed.
