摘要
针对单双频周跳探测法对小周跳探测不灵敏的问题,提出一种基于BDS数据的三频组合相位差分周跳探测法:顾及三频数据组合优化选取原则,采用优选的三频组合在观测值间求差,再进行历元间差分。实验结果表明该方法在原始频点不含周跳时检测量波动范围小于1个周跳,能有效探测1个以上的周跳,为多频数据组合的应用提供参考。
Aiming at the problem that single and double frequency cycle slip detection method is not sensitive to the little cycle-slip, the paper proposed a triple frequency combination phase difference cycle slip detection method based on the BDS da ta： by taking into account of the optimization selection principle of triple-frequency data combination, the difference between the optimized triple-frequency combination observation was made, and the difference between epochs was carried out. Experimental result showed that the detection range of the proposed method would be less than one cycle slip when the o- riginal frequency does not contain the cycle-slip, and it could detect one or more cycle-slips effectively, which could provide a reference for the application of multi-frequency data combination.
