中文摘要	在三频载波相位观测值组合理论基础上,提出一种三频组合模糊度固定方法(TCCAR),并实现了北斗三频数据的快速相对定位。TCCAR方法采用三组弱电离层超宽巷组合,可以快速解算整周模糊度,同时避免周跳问题。实测数据表明,TCCAR法的解算速度比LAMBDA搜索算法提高44.91%,同时对15.26 m的基线实现了mm级的相对定位。; Based on the triple-frequency carrier phase combination observation,this paper propose a simple and efficient single epoch ambiguity fixing method( TCCAR) which can be successfully used to the Beidou triple-frequency rapid relative positioning. In relative positioning,the main problems of traditional lambda search method are cycle slip detection,ambiguity fixing and long search time. TCCAR method could quickly fix the ambiguity by the three combinations of extra wide lane,and also this method could avoid cycle slip problem because it's a single epoch solution. By processing the real data received at 10 May 2013 on the roof of a building at Tsinghua University,TCCAR method could improve the 44. 91% of the solve speed than the LAMBDA search resolution. Finally the triple-frequency relative positioning accuracy could achieve mm level for a 15. 26m baseline.
