双频组合法探测与修复周跳的补充

Complement of Detecting and Repairing Cycle Slip by Combination of Dual Frequency

基于双频单站的探测与修复周跳的方法,把伪距历元差与相位历元差组合作为约束条件,利用双频载波相位观测值组合的方法联合进行周跳探测与修复,并主要针对周跳在频率比附近变化时此方法无法探测的缺点,根据具体实例的分析、总结,采用预先插入周跳法进行补充探测,并对产生的周跳进行了有效修复。

The method of detecting and repairing cycle slips based on dual frequency and single station was discussed in this paper. Accepting the difference of pseudo range observations between different epochs and the difference of carrier phases between different epochs to be the constrained conditions, detecting and repairing cycle slips were put up by using the combination of dual frequency and cartier phases. Considering the problem that the cycle slips could not be detected when they changed near the ratio of different frequency, a complementary method that is to insert cycle slips before detecting was adopted according to the analysis and epagoge of some examples. With this method the cycle slips were repaired efficiently.
