Provided is an MSS satellite system including a satellite, an ATC and an MES. The satellite transmits a signal of a frequency for FSS to the ATC and transmits a signal of a frequency for MSS to the MES. When the strength of the signal transmitted from the satellite is equal to or greater than a reference value, the MES receives the transmitted signal. When the strength of the signal is less than the reference value, the MES transmits the position coordinates and speed information of the MES together with information transmission request, to the ATC. The ATC applies a beam-forming algorithm by using the position coordinates and speed information of the MES and transmits a directivity-enhanced signal to the MES which requests information transmission. |
