The rapid growth of satellite services using higher frequency bands such as the Ka-band has highlighted a need for estimating the combined effect of different propagation impairments.In this paper, propagation characteristics are analyzed under the rain condition of the Korea based on the measurements for Ka-band beacon signal of COMETS that moves in non-geostationary orbit.It is also presented that radio propagation characteristics varying as time, range, and elevation angle.As results, it is concluded that free space loss is a major parameter to the radio propagation characteristics varying as a range in clear sky.In addition, the effect of elevation angle is negligible because COMETS is observed above 40 degree.The beacon signal level of COMETS in rain condition fluctuates much more than that of COMETS in clear sky.
