Abstract

The invention relates to a performance testing method for a positioning apparatus. The method includes the following steps that: a testing apparatus simulates a virtual position to be positioned and simulates a satellite to send corresponding satellite signals to the positioning apparatus; the testing apparatus simulates satellite signal error according to the satellite signals and interposes satellite error interference signals into the satellite signals; the testing apparatus generates a corresponding virtual reference station through simulation, and simulates the virtual reference station to send corresponding differential correction signals to the positioning apparatus; and the testing apparatus sends network transmission interference signals to the positioning apparatus according to acommunication process between the virtual reference station and the positioning apparatus; and the testing apparatus receives a solution result returned by the positioning apparatus, and determines the performance characteristics of the positioning apparatus according to the virtual position and the solution result. With the method adopted, all kinds of tests can be completed indoors, regardlessof weather and location, test efficiency can be effectively improved, and a work cycle can be shortened.

Description

technical field [0001] The invention relates to the field of satellite positioning testing, in particular to performance testing equipment, testing methods and devices of positioning equipment. Background technique [0002] With the rapid development of satellite positioning technology, satellite positioning has developed from the initial absolute positioning technology with low positioning accuracy to RTK (Real-time kinematic, real-time dynamic) carrier phase differential positioning technology with high positioning accuracy. RTK technology is to improve the positioning accuracy by temporarily erecting reference stations in the traditional absolute positioning method to eliminate errors. By setting up fixed and continuously operating reference stations, a more convenient CORS (Continuously Operating Reference Stations) system is formed. Its appearance and extensive construction have greatly improved navigation and positioning in all walks of life. Great convenience. [00...
