Abstract: The satellite-to-satellite range and time difference measurement were necessary to distributed spacecraft and formation flying systems.The method of inter-satellite two-way time transfer (TWTT) is presented.The measurement data process algorithm for TWTT is deduced and the movement influence on TWTT is analyzed in detail.And then the range and time difference errors are given when satellite movement is ignored.

Key words: Two-way time transfer, Crosslink, Calibration error, Error analysis, Satellite Formation flight
