摘要：

In this paper, the accuracy of the trial operation stage BeiDou Navigation Satellite System (BDS) navigation message was analyzed and evaluated from January to December in 2012. The main content of the Beidou performance assessment was briefly introduced together with availability of Beidou precise ephemeris. Then, according to the Beidou mixed multi-satellite constellation characteristics, calculation formula of signal in space was derived, which is exactly suitable for Beidou system. Based on the Beidou precise ephemeris which derived from Position And Navigation Data Analysis software (PANDA) and BeiDou Experimental Tracking Stations (BETS), the accuracy of Beidou broadcast ephemeris, clock errors, Beidou system ionospheric correction model (BeiDou Klobuchar) and the pseudorange Single Point Positioning (SPP) were analyzed in details.
