| Abstract: | Satellite orbit getting with the dynamic determination method is significantly biased from its real position at the occurrence of satellite orbit abnormity, which will lead to serious influence on the positioning accuracy of the users. A method with wavelet analysis technique based on geometric orbit determination for GEO satellite abnormity recognition is proposed and then the grouping fixedly scheme and the opening window scheme are designed for dealing with the geometric orbit determination results during the COMPASS satellite maneuver period. According to the analysis results, both kinds of scheme can distinguish the happening time of satellite abnormity exactly and the resolution is better than five seconds. |
