Abstract
Medium-long baseline static positioning algorithm based on BeiDou dual-frequency observations is proposed first. In this paper, we concentrate on the processing strategy of atmosphere errors. We form four baselines in different days using data of B1 and B2 from HongKong CORS and Wuhan CORS (each CORS forming two baselines). In the experiment, we analyze the fix rate and positioning accuracy in different time periods (2, 3, 4 and 6 h). The results indicate that the poor geometry condition and slow variation of geometry in BDS constellation contribute to the poor performance than that of GPS, which drives us need more time(at least 4 h) to ensure reliable fixed solution and centimeter level positioning using BeiDou dual-frequency observations in medium-long baseline static positioning.
