  • Abstract
    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.
