相位减伪距法与电离层残差法探测和修复周跳

Research on detection and reparation for cycle slips using phase reduce false distance law and ionized layer remnant method of difference

在GPS精密定位数据处理中,周跳的探测和修复是一个核心问题。针对电离层残差法周跳探测存在的多值性问题以及相位减伪距法对小周跳不敏感等方面的不足,提出将两种方法联合进行周跳处理的方法。实例分析表明,方法简单可行,处理效果比较理想。

The cycle slips detection is one of the core problems in the GPS data processing.The phase reduce false distance law has a multivalued trait and the ionized layer remnant method of difference is not sensitive to little cycle slips.In view of those drawbacks,the two methods are combined to process the cycle slips. The test results prove the effectiveness of this new method.
