Embodiment Construction
[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0058] refer to Figure 1-Figure 4 , a fast positioning method based on low-orbit satellite multiple coverage scenarios, including the following steps:
[0059] S1: The receiver simultaneously receives satellite broadcast signals 1 to N, analyzes the satellite number information, satellite position information, satellite speed information and beam position information and stores them locally;
[0060] S2: The receiver simultaneously receives the ranging signals sent by No. 1~N satellites, analyzes and obtains pseudo-range observation information and Doppler observation information and stores them locally;
[0061] S3: Determine the number N of satellites covered by ...
