Open-type cloud testing control system and method based on navigational signal typical scene base

Abstract

The invention belongs to the technical field of navigation testing, and discloses an open-type cloud testing control system and method based on a navigational signal typical scene base. A service center is connected with a data acquisition instrument, a monitoring terminal and a testing terminal through a network. After true navigation signals and locating information given by RTK+INS are obtained, the service center verifies the validity of the collected data, and provides calibration parameters of the collected data at the same time; the calibrated parameters are subsequently stored with original data; different channel parameter combinations are utilized to describe different types of obstacles according to the influence on different parameters of navigation signals, wherein for each type of obstacle model, the statistic features under various typical environments also vary from each other, and need to be analyzed through actually measured data. By means of the open-type cloud testing control system and method based on the navigational signal typical scene base, a unified platform is provided for testing a navigation receiver, and the consistency problem of detection results ofdifferent detection mechanisms regarding the same sample is solved; through data sharing, diversification of a data collection scene is achieved at a low cost.

Description

technical field [0001] The invention belongs to the technical field of navigation testing, and in particular relates to an open cloud testing control system and method based on a typical scene library of navigation signals. Background technique [0002] At present, there are three ways to test the performance of the Beidou navigation terminal: one is to use the navigation signal simulation source test in the laboratory environment, the other is to use the outdoor receiving antenna to test the performance of the sky, and the third is to use the acquisition and playback device to conduct virtual road test. In the laboratory environment, the satellite signal simulation source can be used to quantitatively test the first positioning time and positioning accuracy of the tested sample. However, because the simulator signal is a simplification of the real satellite signal, it cannot completely simulate the real environment, so it is impossible to evaluate the measured sample. The p...
