Embodiment Construction
[0022] 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 part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0023] In a preferred embodiment, as reference figure 1 and image 3 Shown: If the parent satellite of A2 in the positioning system is A1, there is no spare parent satellite; the parent satellite of A4 is A1, and there is no spare parent satellite; the parent satellite of A3 is A4, and the spare parent satellite is A1. During the synchronization chain self-optimization method of the positioning system, the positioning system is in the positioning mod...

The invention discloses a positioning system and its synchronization chain self-optimization method, which is characterized in that, in the positioning mode, the distance measurement between the satellite and the parent satellite is performed, and the quality of the parent satellite is judged according to the distance measurement result; if the If the quality of the parent satellite is unqualified, it is judged whether the satellite has a backup parent satellite, if so, the backup parent satellite is enabled and the backup parent satellite is set as the current parent satellite of the satellite in the synchronization chain, etc., It automatically optimizes the synchronization chain of the positioning system, so that the quality of the synchronization chain is always good, and effectively solves the problem that the occlusion of the satellite changes due to decoration or furniture moving, which leads to the decline in the quality of the set synchronization chain. Positioning system reliability and positioning quality.
Description
technical field [0001] The invention relates to the technical field of positioning, in particular to a positioning system and a synchronization chain self-optimization method thereof. Background technique [0002] In the existing positioning system, it is composed of several father and son satellites, and a synchronization chain is formed between the father and son satellites. Whether the parent satellite setting in the positioning system is reasonable is the key to the synchronization quality of the whole network. Ranging is an important means to test whether the parent satellite is suitable. The positioning system is in the positioning mode when used, and the positioning mode is characterized by synchronization between satellites. During positioning, the two-way ranging function cannot be completed. [0003] In the prior art, when the current parent satellite is not suitable, self-adjustment cannot be performed to a certain extent to maintain the normal operation of the...
