Multi-feature comprehensive satellite selection method based on entropy weight TOPSIS

The invention relates to the technical field of satellite navigation and positioning, and provides a satellite selection method for comprehensive decision making based on characteristic parameter change characteristics. Therefore, the technical scheme adopted by the invention is as follows: according to a multi-feature comprehensive satellite selection method based on entropy weight TOPSIS, a visible satellite comprehensive quality evaluation sequence is obtained by taking a plurality of feature parameters solved by a satellite receiver as satellite evaluation indexes and applying an entropy weight approximate ideal solution sorting method TOPSIS for evaluating the difference between different objects and good and bad targets in the field of multi-target decision making; grouping the visible satellites according to the evaluation sequence; on the basis of grouping, contribution of visible satellites to navigation and positioning services is considered, and satellites participating in positioning are screened
