Abstract

The invention relates to a multi-station positioning algorithm verification method and a simulation system. The method comprises the steps of performing scene setting through a system interface, and setting a station quantity, station distribution, a target quantity and a target track; calculating target track points according to the set target quantity and target track, and performing group storage on the target track points according to recorded initial time marks; performing calculation according to position coordinates of the grouped target track points, station distribution coordinates and the initial time marks of the target track points to obtain time marks of receiving the target track points by stations; performing ascending group sorting on the grouped target track points according to the time marks of receiving the target track points by the stations; and performing scene display on the time marks of receiving the target track points by the stations and the grouped target track points subjected to ascending group sorting, packaging the time marks and the grouped target track points as verification data, sending the verification data to-be-verified software, and performing multi-station positioning algorithm verification.

Description

technical field [0001] The invention relates to the technical field of information positioning, in particular to a multi-station positioning algorithm verification method and a simulation system. Background technique [0002] At present, multi-station positioning mainly includes multi-station cross positioning and multi-station time difference positioning. Among them, multi-station cross positioning is a method of obtaining target distance information by using multi-station angle information. Generally, two-station can be used to complete the three-dimensional of the target. Multi-station time difference positioning is also called hyperbolic positioning. It is a more accurate positioning method. The time difference between the radiation signal of the target and the two stations determines a pair of hyperboloids with the two stations as the focus. Three-dimensional positioning requires four A passive station generates three pairs of hyperboloids, the intersection of the surfa...
