Example Embodiment
[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0036] like figure 1 As shown, the method for eliminating anomalies in satellite navigation and positioning of the present invention includes the following steps:
[0037] In step S1, in the information preparation stage, the observation data of all visible stars are obtained at fixed time intervals, the obtained observation data information is demodulated, pseudorange and ephemeris information is obtained, and stored locally.
[0038] Step S2, then, enter the positioning information preparation stage after preparing the ephemeris and pseudorange information, check whether the ephemeris information stored in the local is in the same update cycle, if so...
