BeiDou satellite navigation system constituted by 14 satellitesannounced the formal operation in December 27,2012. The paper expounded the positioning principle of BeiDou navigation positioning system based on discussing the lat-est developments of BeiDou measurement system. Then from the perspective of the use of the users, the paper preliminarily analyzed the performance of BeiDou satellite navigation system based on the observation date from the actual test environment in Dalian area from the satellite visibility, the attenuation of position precision, the single point positioning precision, the differential positioning precision. This paper attempted to provide a basic reference for the users of BeiDou satellite naviga-tion system in Bohai region.
