| 摘 要： | 针对GPS双频接收机定位的特点,结合目前较成熟的探测和修复周跳方法的优点,提出了一种探测和修复周跳的新方法,即基于电离层残差法和相位减伪距法的优点,将两种方法进行合理的组合。该方法根据接收到的载波相位,联合利用电离层残差法和相位减伪距法进行周跳的探测与修复。从理论上说明了该方法的可行性,实例分析表明:该组合方法原理简单,计算速度快,实用性强。

| Abstract: | In view of the characters of position with dual-frequency GPS, a new algo- rithm of cycle slips detection and reparation is proposed, which is based on the advantages of current approaches, the ionized layer remnant method of difference and the phase reduce false distance law approaches for rational combination method. According to the received car- rier phase, the joint use of the ionized layer remnant method of difference and-the phase re- duce false distance law approaches is employed to effectively detect and repair cycle slips. The feasibility of this method is presented, and the test result shows that this combination method is simple, fast calculation, and practical. |
