NON-INTERFERING UTILIZATION OF NON-GEOSTATIONARY SATELLITE FREQUENCY BAND FOR GEOSTATIONARY SATELLITE COMMUNICATION

摘要

A method and system of utilizing non-geostationary satellite orbit (NGSO) frequency spectrum in a geostationary satellite orbit (GSO) satellite communication system in a non-interfering manner. The GSO satellite communication system comprises an Earth terminal to transmit signals to a GSO satellite using a GSO frequency spectrum, the Earth terminal further operable to transmit signals to the GSO satellite using an extended frequency spectrum, the extended frequency band including the GSO frequency spectrum and a non- geostationary (NGSO) frequency spectrum; a command center operative to instruct the Earth terminal to transmit signals to the GSO satellite using the GSO frequency spectrum, when an NGSO satellite is expected to be in-line with respect to the Earth terminal and the GSO satellite; and wherein the command center is further operative to instruct the Earth terminal to transmit signals to the GSO satellite using the extended frequency spectrum, when no NGSO satellite is expected to be in-line with respect to the Earth terminal and the GSO satellite.
