A multi-station positioning algorithm verification method and a simulation system

Abstract

The present invention relates to a multi-station positioning algorithm verification method and a simulation system. The method includes: setting the scene through the system interface, setting the number of stations, the distribution of stations, the number of targets, and the target trajectory; according to the set target number, The target trajectory calculates the target trajectory points, and stores the target trajectory points in groups according to the recorded initial time scale; calculates the location coordinates of the grouped target trajectory points, the distribution coordinates of the stations, and the initial time scale of the target trajectory points. The time stamp of the track point; according to the time stamp of each target track point received by each station, sort the target track points of each group in ascending order; sort the time stamp of each target track point received by each station and the group targets sorted in the ascending order The track points are displayed in the scene, and sent as verification data to the software to be verified for verification of the multi-station positioning algorithm. The invention solves the problem that the accuracy cannot be guaranteed in the verification of the multi-station positioning algorithm in the current physical construction.

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...
