Patent ID: 7806369

Claim:
An ultrahigh altitude sun-synchronous orbit satellite system, comprising: one or plural satellites orbiting the sun such that the one or plural satellites revolve around the earth in a substantially circular or elliptic motion at an altitude of several million kilometers from the earth, said altitude of several million kilometers being beyond the sphere of earth gravity influence, said one or plural satellites being placed on an orbital plane relative to both the sun and the earth and keeping the distance and geometry between the one or plural satellites and the sun and between the one or plural satellites and the earth substantially constant, the satellite system performing any one of the services of space observation, global observation, and satellite communication, wherein the one or plural satellites orbit the sun with both inclination and eccentricity distinct from those of the earth revolution and revolve around the earth with a sun synchronous property in which the local solar time is kept constant at a point on the surface of the earth directly beneath the satellite.
