HIGH LATITUDE GEOSTATIONARY SATELLITE SYSTEM

摘要

A satellite broadcast and communications system employing a constellation of satellites in highly elliptical and highly inclined orbits, where the satellites remain almost stationary relative to ground users, describing a small loop in the sky around the apogee of the orbit for long periods of time. A user on the ground with conventional directive antenna will be provided with continuous communication services, without interruption, 24 hours per day. The small loop where the satellites are operational is located around the highest latitude of the orbit. Therefore, it will have a high angular separation from satellites operating in the equatorial geostationary satellite orbit (hereafter more simply referred to as the geostationary satellite orbit), thus enabling a full sharing of the frequency bands used by the geostationary satellite orbit systems, without causing any interference between the two types of satellite network systems, and without the need for any interference mitigating factors. The users of this orbit are able to see a completely seamless transmission service from satellites without the need of switching between satellites, or service interruptions.
