Real time clock error

After the examples are analyzed, there are problems which need to be solved such as ambiguity, real-time clock bias error and the estimate method of zenith wet delay.

通过对算例的分析，提出需要解决的问题：整周模糊度、实时钟差和天顶湿延迟的估计方法。

A new tool that can test the clock base frequency error of energy measuring devices and provide GPS standard time to calibrate real-time clock was introduced in this paper.

介绍了一种用来测量电能计量装置的时钟基频误差，并提供GPS标准时间以校准其实时时钟的新型工具。
