摘要 本文给出了伪距相位组合、Geometry-free(电离层残差)组合和MW(Melbourne-wubbena)组合探测周跳的数学模型,并基于最小方差原理顾及各项误差对三种组合的周跳探测能力进行了比较。利用北斗数据进行算例分析,结果显示同时使用Geometry-free组合和MW组合时可以探测几乎所有周跳和0.1周以上的粗差,比伪距相位组合有着更高的周跳探测灵敏度。 The Mathematical models of pseudo - range/carrier phase combination, geometry - free combination and melbourne - wubbena combination for cycle slip detecting are given in this paper, and comparison of the cycle slip detecting ability of these combinations are made based on the least - variance principle and kinds of errors. Then the test of cycle slips detection with Beidou data is conducted, and the result shows that using geometry - free combination and melbourne - wubbena combination simultaneously can detect almost all cycle slips and gross error up to 0. 1 cycle, which offers a higher sensitivity to cycle slips and gross error detection than pseudo- range/carrier phase.
