Preliminary Results of Single Epoch Baseline Solution Based on Beidou Navigation Satellite System

  • The Beidou navigation satellite system has been in trial operation since last year,and will provide services in China and its surrounding areas at the end of 2013.We first analyze the system’s satellite visibility in Wuhan,and discuss the Beidou ambiguity resolution(AR) algorithm for short baseline.Experiments were conducted using the dual-frequency GPS/Beidou data collected in Wuhan and processed with GPS and Beidou system separately.The preliminary results indicate that the current Beidou system has the ability of precise positioning capacity.For the short baseline(≤ 15 km) of the Beidou system,the success rate of single epoch ambiguity resolution reaches 80%.The final positioning precision is better than 3 cm on the horizon,and is better than 6 cm for elevation.
