摘要： A communication-satellite system for providing communication services to the entire Earth is based on a plurality of satellites in low-earth-orbit (LEO). The satellites orbit the Earth in a plurality of orbits, with multiple satellites in each orbit. This orbital arrangement results in some locations on the surface of the Earth receiving redundant satellite coverage. Embodiments of the present invention can selectively and adaptively rotate the orientation of some of the satellites so as to transfer some of the redundant coverage from locations where it is not needed to locations where the redundant coverage is advantageous.

摘要： A constellation, including a plurality of spacecraft, including a first, second and third spacecraft, each of the plurality of spacecraft including a broadcast capability, and each of the plurality of spacecraft in its own approximately 24-hour orbit (501). Each of the orbits (501) has a substantially teardrop-shaped or oval-shaped ground track, is optimized based upon elevation angle or probability of signal availability, and has an apogee longitude of approximately 90° west to approximately 100° west. Each of the orbits has a semi-major axis of approximately 42,164 kilometers, an argument of perigee of approximately 270°, an inclination of approximately 40° to approximately 60°, and an eccentricity of approximately 0.16 to approximately 0.4. The orbits of each of the plurality of spacecraft are selected to bring each of the spacecraft to apogee at time increments of approximately eight hours.

摘要： Satellite communication systems are provided that employ highly inclined, highly elliptical orbits. The satellite communication systems have a satellite constellation phased to provide a ground trace with respect to the earth that is repeated by each of the satellites in the constellation such that the satellites appear to follow one another over similar paths over the earth. Due to the path of the ground trace provided, ground stations can employ a single axis tracking device since the satellites appear to move along similar overlapping paths in opposing directions relative to a user on the ground during communication control handoffs.

摘要： A coordinatable system of geosynchronous (24-hour), inclined, and slightly elliptical satellite orbits enables spectrum re-use by forming "highways" of moving "slots" in the latitudes above and below the geostationary (GSO) belt world-wide. Each of a plurality of repeating ground tracks (12) is shared by multiple satellite orbits (and thus slots). These are phased to achieve minimum specified angular separation from other slots using the same frequencies. Ground track (and thus orbital) parameters are chosen to realize specified shapes and are located at specified longitudes of symmetry to maximize the total number of slots. Consideration is given to specified constraints on service area coverage, elevation angle, and time coverage.

摘要： A communication system (40) has a plurality of ground stations (54) for communicating communication signal to a plurality of satellites located in an inclined elliptical subgeosynchronous orbit (34) with respect to the earth (10). The plurality of satellites (32) operate in a service area (52) in a synchronized manner to provide continuous coverage to the service area (52). The satellites (32) generate a plurality of beams with variable beamwidths to obtain a substantially uniform cell size covering the service area. A user terminal within the service area receives communication signals from the satellite (Fig. 2).
