| 摘 要： | 介绍了使用同源共视技术进行频率校准的基本原理,在此基础上分析和评定了共视技术引入的不确定度。共视技术中不确定度主要是由参考原子钟的频率准确度、两地接收系统的不确定度、卫星的位置误差、接收天线的位置误差所构成。经过计算评定,在所有的影响不确定度的因素中,参考原子钟的频率准确度最为重要。

| Abstract: | The theory according to common-view method to adjust frequency is introduced.And then analyses the uncertainty from common-view method and also assess it.The factors which effect the uncertainty from common-view method is mostly come from frequency accuracy of reference atomic clock, the uncertainty from receiving system,the position error of satellite,the position error of receiving system's antenna.The result revealed that the frequency accuracy of reference atomic clock is the most important factor to effect the uncertainty from common-view method. |
