U.S. Cl. 244--158 R 33 Claims
1. A constellation of telecommunication satellites which
provides 24-hour cellular telephone communication coverage over a
predetermined latitude range around the world for a cellular transceiver
having an omni-directional antenna operating at a power level as low as
1/2 watt, comprising:
a plurality of less than 9 telecommunication satellites providing
24-hour cellular telephone communication coverage over a predetermined
latitude range around the world which is less than whole earth coverage,
each of said satellites having a plurality of multibeam antennas for
enabling simultaneous bi-directional communication links with a
plurality of cellular-based telecommunication devices;
each of said satellites residing in one of a plurality of
predetermined orbits, with the number of said predetermined orbits being
different than the number of said satellites in each of said
predetermined orbits; and
each of said predetermined orbits being related to the other
orbits such that each of said predetermined orbits has a predetermined
inclination angle with respect to the equator, a predetermined altitude
of between approximately 5600 nmi and 7500 nmi, and a predetermined
ascending node spacing between satellites in different orbital planes.
