Non-interfering utilization of non-geostationary satellite frequency band for geostationary satellite communication
First Claim
1. A command center of a geostationary orbit (GSO) satellite communication system comprising:
- a data processing unit for identifying an occurrence of an in-line event involving a GSO satellite and a non-geostationary orbit (NGSO) satellite; and
a network control unit coupled to the data processing unit for (i) instructing, if occurrence of an in-line event is not identified, a GSO earth station to transmit to the GSO satellite a signal at least partially occupying a frequency spectrum allocated to a NGSO signal on a primary basis; and
(ii) instructing, if occurrence of an in-line event is identified, the GSO earth station to transmit to the GSO satellite a signal not occupying the frequency spectrum allocated to the NGSO signal on a primary basis.

Abstract
A method, satellite and system utilizes non-geostationary satellite orbit (NGSO) frequency spectrum in geostationary satellite orbit (GSO) 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 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.
