| 摘 要： | 利用各频率观测值间物理上的相关性,采用数学变换得到一个含有双频原始载波观测信息的虚拟观测值,与双频数据按长波长特性进行多频组合来放大周跳。对探测出的周跳候选值利用Melbourne-Wubbena组合及多项式拟合作为两个判别条件来进行甄选,达到了实时修复双频原始载波相位观测值周跳的目的。

| Abstract: | The third frequency carrier phase virtual observation is produced by numerical transform through the physical relationship of each frequency carrier phase observations.Using long-wave character of multi-frequency combination,a group of long-wave combinations are formed to detect cycle slip of GPS double-frequency raw carrier phase observations in different conditions through the pseudorange/carrier phase combination method and get a group of cycle slip candidate.Then we use Melbourne-Wubbena combination get the difference on each epoch of wide-lane to judge the true cycle slip.The result shows that this method can real-time fix the cycle slip of double-frequency origin carrier phase observations. |
