摘要

我们对一台Z12-T Metronome测地GPS接收机时间中转站进行了改进，增加了一个时间间隔计数器(SR-620)来测量其外部参考1 PPS和20 MHz频率输入之间的时间差。时差被补偿到其RINEX文件的伪距测量中。因此，修改后的RINEX伪距和CGGTTS的REFGPS的参考时间被重新定义为系统的外部1pps参考时间，不再是其外部20mhz频率输入。

A modification of Z12T metronome time transfer system

We modified one Z12-T Metronome geodesic GPS receiver time transfer station by adding a time interval counter (SR-620) to measure the time difference between its external reference 1 PPS and 20 MHz frequency inputs. The time differences were compensated into the pseudorange measurement of its RINEX file. In consequence, the reference time of the modified pseudorange of RINEX and REFGPS of CGGTTS are re-defined to be the system's external 1 PPS reference, no more its external 20 MHz frequency input.
