摘      要：In order to develop the technique of Laser Time Transfer(LTT) ,Shanghai Astronomical Observatory has built a prototype of space-borne LTT module. The performance of the LTT module and the results of ground tests are discussed in the paper. The average precision of time difference between two rubidium clocks measured by laser pulses is 196 ps,and the uncertainty of measurement for the relative frequency differences is 1.2×10-13/2800 s.
