接收机钟跳对VRS改正数生成的影响分析

VRS技术是网络RTK系统中应用最广泛的一种技术方法，它依赖于对基准站间空间相关误差的构建。基准站的接收机由于钟差的调整会产生钟跳，钟跳不仅会对观测值产生影响，还会造成VRS改正数的不连续。从VRS改正数生成的数学模型出发，分析了不同钟跳对观测值和改正数的影响，给出了针对钟跳的观测值和改正数的修复方法。以两个CORS网中的观测数据为例进行了实验验证，证明了算法的正确性和可靠性。

Analyzing the Effect of the Receiver Clock Jumps on VRS Corrections

VRS technology is the most widely used technical method of network RTK systems, which relies on the construction of space related error between the base stations. Reference station receiver clock jumps due to the adjustment of clock error. Clock jumps will not only have an impact on observations, but also cause the discontinuous VRS corrections. From the mathematical model generated by VRS corrections, this paper analyzes the different influence on the observations and corrections of clock jump. It also gives the method of fixing the observations and Corrections. The method is proved to be correct and effective.
