Zusammenfassung:PURPOSE: A net synchronizer of a mesh type satellite net for MF-TDMA communication is provided to obtain initial synch by using synch obtaining channel in each terminal. CONSTITUTION: A sync obtaining unit(130) synchronizes a transmission signal to a transmission time. The sync obtaining unit synchronizes a receiving signal to a receiving time. A sync sustaining unit(140) periodically receives timing error of a terminal from a satellite center station. The sync maintaining unit periodically synchronizes transmission time applying the receiving timing error. The synch maintaining unit periodically synchronizes a receiving time applying the received timing error.
