a method , satellite and system utilizes non - geostationary satellite orbit frequency spectrum in geostationary satellite orbit satellite communication in a non - interfering manner . a ground station transmits signals to a gso satellite using a gso frequency band and an extended frequency spectrum including the an ngso frequency band whenever a noninterference situation exists , i . e ., when an ngso satellite is not in - line between the earth terminal and the gso satellite or when the ngso satellite is not utilizing the ngso band of interest . a command module is provided to instruct the ground station to transmit signals to the gso satellite using the gso frequency band and the extended frequency spectrum .
