摘要

2012年10月，对OCA的gsamoazur TF实验室进行了重组，以提高信号分布的稳定性。特别地，我们实现了一种基于h脉泽T4Science的新型时标TA(OCA)。h脉泽频率由HROG-10微相步进器控制。考虑到自由运行脉泽的频率和TA(OCA)与UTC(OP)之间的实际时差，每天计算应用的校正。主要思想是保持我们当地时间尺度TA(OCA)和UTC之间的时间差低于50 ns，以便对单反激光脉冲进行时间标记，并使卫星与激光站之间的距离测量误差低于1 mm。

Remote steering of OCA local time scale using UTC(OP)

In October 2012, the Géoazur TF laboratory in OCA has been reorganized to improve signal distribution stability. In particular we have implemented a new time scale TA(OCA) based on H-maser T4Science. The H-maser frequency is steered with an HROG-10 microphase stepper. The correction applied is computed every day taking into account the frequency of the free running maser and the actual time difference between TA(OCA) and UTC(OP). The main idea is to keep the time difference between our local time scale TA(OCA) and UTC below 50 ns, in order to time tag the SLR laser pulses and to have an error below 1 mm for distance measurement between satellite and laser station.
