Due to the characteristics of open system and weak signal power of satellite navigation signal, it is very easy to be affected by navigation deception and other interference. At present, most studies divide the influence of deception signal on the receiver into two independent aspects: positioning and timing. There is a lack of research on accurately controlling the positioning and timing of the receiver in the process of deception. In this paper, the principle of accurately controlling positioning and timing in navigation deception are analyzed, three deception scenarios are proposed and verified by experiments. The experiments show that :1) it is feasible to introduce a step or linear position deviation to the receiver without excessively affecting the timing results; 2) it is feasible to introduce a step or linear time deviation to the receiver without excessively affecting the positioning results:3) it is feasible to perform position spoofing and time spoofing on the receiver at the same time, the positioning results of the receivers were successfully pulled off by 60m in the experiment, while their timing results were pulled off by 1.5μs.
