Abstract:	Ultra-precise optical time transfer in space enables global time distribution and enhanced global positioning systems. The feasibility of stable optical time transfer between static terminals has been verified, however the system has to be validated in space to prove its robustness and performance for an application on navigation satellites. Optical links with precise time and frequency transfer from the low earth orbit to ground in frame of the COMPASSO mission shall be performed. We propose a system design which copes with the constraints and performance requirements of the mission. The system is described and preliminary results of the breadboard are shown.
