Abstract

This paper deals with the possibilities of the satellite diversity (Sat.D) system for VSAT Earth-station. From three satellites, JCSAT-1, JCSAT-3 and the Broadcasting Satellite (BS), the down-link signals are measured in the experiments, and the diversity gains are obtained by a Sat.D simulation program. The Sat.D characteristics are compared between rain attenuation and snow attenuation. The Sat.D results for snow attenuation show that the Sat.D can be effectively utilized for the VSAT system. However, the Sat.D gains for rain attenuation were smaller than those for snow attenuation. This may be due to differences in cloud size, topographical conditions near the Earth-station and the wind direction.
