  • Patent number: 7107007
    Abstract: A positioning system for a geostationary satellite according to the present invention comprises a plurality of outer orbit satellites revolving around the earth in equatorial orbit and polar orbit having higher altitude than that of the geostationary satellite; and at least one control station performing orbit determination using tracking data for the outer orbit satellites, and then transmitting consequent orbit data to the outer orbit satellites. The outer orbit satellites transmit to the geostationary satellite their own navigation data, clock data and correction data generated using the orbit data received from the control station. The geostationary satellite calculates its own position using the navigation data, the clock data and the correction data, and performs position control and attitude control autonomously with onboard sensors and actuators.
