| Abstract: | In order to make a comprehensive assessment of service performance for Beidou Satellite Navigation System since the service in operation formally, four positioning models which are B3 single frequency positioning, B1／B3 dual frequency positioning, B3 single frequency differential positioning and B1／B3 dual frequency differential positioning are given in this paper firstly, and then positioning strategy is designed to take into account IODE／IODC ephemeris and clock age, and last the time and the spatial characteristics of 4 kinds of positioning model are analyzed and evaluated using the continuous monitoring network data in the Chinese region. The continuous three year results of Beijing area,Hainan and Xinjiang area is presented. |
