ABSTRACT:
A method of determining the position of an observation point on the earth using M satellites on a stationary orbit which has a predetermined orbit inclination angle such that N (<M) satelites are in the range of vision of the observation point. One of the N satellites generates a reference signal at a known time. This reference signal is sent directly to the observation point, sequentially relayed by the remaining satellites and transmitted from the respective satellites to the observation point. The observation point measures the differences in time of reception of the signals from the N satellites and determines the positions of the N satellites. The position of the observation point is determined as an intersecting point of the hyperboloids each placing the foci on adjacent two of the satellite positions.
