SPREAD SPECTRUM COMMUNICATION SYSTEM USING A QUASI-GEOSTATIONARY SATELLITE

摘要

The invention refers to a satellite communications system with a mobile user terminal. In order to provide a satellite communications system which enables communication with a mobile user terminal via conventional communication satellites on any area of interest on earth, a quasi-geostationary satellite is operated in an inclined orbit and sends a spread downlink signal s'(t) to said area of interest on earth to be received and despreaded by a mobile user terminal.
