1. A method comprising:
- providing a first satellite that travels an inclined geosynchronous orbital path having an equatorial crossing,preventing transmissions between the first satellite and Earth stations when the first satellite travels at least a first portion of the path,permitting transmissions between the first satellite and Earth stations when the first satellite travels at least a second portion of the path, the first portion of the path being relatively closer to the equatorial crossing than the second portion of the path.

Abstract
The present disclosure is directed to an inclined geosynchronous orbit satellite system that can efficiently provide continuous communication to multiple geographic regions across the world using satellites in inclined geosynchronous orbital paths having an equatorial crossing and enabling the reuse of frequencies assigned within GSO orbital locations. The inclined orbit satellite system can include multiple inclined orbit satellites that are capable of co-existing with geostationary satellites to provide continuous uninterrupted service.

7. A system comprising:
-
a first satellite that travels an inclined geosynchronous orbital path having an equatorial crossing, a transmitter in the first satellite that attenuates transmissions between the first satellite and Earth stations when the first satellite travels at least a first portion of the path, wherein the attenuated transmissions prevent interference with transmissions between geostationary satellites and Earth stations, a transmitter in the first satellite that permits unattenuated transmissions between the first satellite and Earth stations when the first satellite travels at least a second portion of the path, the first portion of the path being relatively closer to the equatorial crossing than the second portion of the path. - View Dependent Claims (8, 9, 10, 11, 12)

19. A method comprising:
-
receiving a transmission originating from a first satellite when the first satellite travels at least a first portion of an inclined geosynchronous orbital path having an equatorial crossing, not receiving a transmission originating from the first satellite when the first satellite travels at least a second portion of an inclined geosynchronous orbital path having an equatorial crossing, the first portion of the path being relatively closer to the equatorial crossing than the second portion of the path. - View Dependent Claims (20, 21, 22, 23, 24)

25. An antenna system comprising:
-
a reflector configured to reflect signals to and from a satellite traveling an inclined geosynchronous orbital path having an equatorial crossing, at least one feed element array configured to receive signals from the reflector and transmit signals to the reflector, a transmit unit connected to the at least one feed element array configured to transmit signals for communication with the satellite to the at least one feed array, a receiver unit connected to the at least one feed element array configured to receive and process signals from the at least one feed element array, wherein the antenna system is configured to communicate with the satellite when the satellite travels at least a first portion of the path being relatively farther from the equatorial crossing than a second portion of the path. - View Dependent Claims (26, 27, 28, 29)
