Application of clock distributor in SLR system

This paper presents the test results of a clock distributor, which was applied to Changchun and Beijing Satellite Laser Ranging (SLR) system. It gives out the ground target calibration results and ranging satellite results. After applying the clock distributor, the precision of calibrating ground targets and ranging satellites has several mm improvements. It also shows the comparison results of standard frequency source provided only by HP58503A GPS receiver and by HP58503A GPS receiver through the clock distributor.
