发明名称 Method of receiving signals through satellites
摘要 A communication/broadcasting system provides a communication service and/or a broadcasting service between a communication/broadcasting center station and a mobile station and a fixed station present in a beam spot through orbiting satellites controlled by a satellite control station in order to prevent a degraded quality and permit users to receive the provision of the services at any location in a service area through the satellite positioned at an elevation angle suitable for communications/broadcasting. The orbiting satellite is switched to another at a timing at which the elevation angle can be kept high, thereby preventing a degraded quality of communications/broadcasting.
