Abstract: Provided are a beacon signal generating apparatus and a phase synchronizing apparatus using the same for establishing a phase synchronization while tracking a phase variation of a Timing Source Oscillator (TSO) of a satellite using a simpler scheme at an earth station, in making a phase synchronization between a clock signal of an On board Switch (OBS) embedded in the satellite and that of the earth station in a Satellite Switched Time Division Multiple Access (SS-TDMA) satellite communication system. The inventive beacon signal generating apparatus embedded in a satellite comprises a frequency oscillator for creating a TSO frequency, a beacon signal generator for multiplying the TSO frequency to be matched with a beacon signal frequency to generate a beacon signal synchronized with the TSO frequency, and a transmitter for transmitting the beacon signal to each of earth stations to recovery a frequency synchronized with the TSO frequency.
