[0050] specific implementation plan
[0051] Below in conjunction with accompanying drawing, asynchronous carrier phase difference relative positioning method is further described in the present invention:
[0052] The present invention "a real-time Beidou precise relative positioning method", its main idea is to use the historical time satellite navigation measurement data broadcasted by the base station with a low update rate and the current satellite navigation measurement data of the mobile station to perform time-asynchronous inter-station carrier phase difference Relative positioning, such as figure 1 As shown in the figure, Sv 1 and Sv 2 means satellite, t 0 Indicates the observation epoch, and Δt indicates the sampling interval of the mobile station. The specific steps are as follows:
[0053] (1) Integral ambiguity parameter initialization
[0054] Use the synchronous observation data of the reference station and the mobile station to initialize the integer ambi...
