Abstract: The demand for higher accuracy in time synchronization makes free-space optical links necessary for time-frequency transfer. FSTWOTT will provide satellite-to-satellite, satellite-to-ground and ground-to-ground time-frequency transfer with a precision and accuracy outperforming the radiofrequency techniques. With RAFS or Hydrogen maser on GEO/IGSO and MEO satellites, the time stability better than 1ps and accuracy better than 100 ps can be achieved, at least one order of magnitude is better in the optical region than the radiofrequency region. Groundbreaking work has been done in developing space laser-communication links for high-speed data transmission from satellites to ground and also between satellites; we are developing toward the compatibility with the next generation of space laser-communication links, making high-precise time-frequency transfer and high-speed data transmission on a link at the same time to be completed.
