Abstract

The invention relates to a Beidou navigation system fault detection method and detection system based on a K-means++clustering algorithm. The method comprises the following steps that according to clustering calculation of initial standard satellite parameters and Beidou satellite parameters, the Beidou satellite parameters are matched with the initial standard satellite parameters; the initial standard satellite parameters are correlated to a corresponding threshold calculation model of satellite specific parameters; satellite specific parameters of a Beidou satellite are received in real time and are input into a satellite specific parameter threshold calculation model correlated to a matched initial standard satellite, and a satellite specific parameter threshold range of the Beidou satellite is calculated; and whether the satellite specific parameters of the Beidou satellite are within the satellite specific parameter threshold range is judged, if no, the satellite specific parameters of the Beidou satellite are fault parameters. The satellite specific parameters are received in real time, the satellite specific parameter threshold range is calculated, and the satellite specific parameters and the satellite specific parameter threshold range are compared to judge whether the satellite specific parameters are fault parameters. The method can be fully suitable for Beidou satellite hybrid constellation.

Description

technical field [0001] The invention relates to the technical field of Beidou navigation system detection, in particular to a Beidou navigation system fault detection method and detection system based on K-means++ clustering algorithm. Background technique [0002] In the integrity detection of the global satellite navigation system, the B-value algorithm of multi-reference reception consistency detection is generally used. However, in the Beidou navigation system, the satellites are a mixed constellation, in addition to 27 medium earth orbit (MEO) satellites, there are 5 geostationary orbit (GEO) satellites and 3 inclined synchronous orbit (IGSO) satellites. The B value detection algorithm in the traditional GPS (Global Positioning System, Global Positioning System) is only applicable to satellites in the middle earth orbit, while the Beidou navigation system is a mixed constellation system composed of satellites in the middle earth orbit, geosynchronous satellites, and inc...
