Abstract

A method and apparatus for providing an improved satellite-based tracking system use a reference transmitter at a site with a known location to provide an error correction vector, which can be applied to improve the position estimate of transmitter at unknown locations. The technique of determining the position of a transmitter on the ground is known as geolocation. For the purpose of geolocation, a transmitter/receiver (transceiver) (306) is interrogated via a satellite ground station through a satellite transponder (304) in Earth orbit. Upon reception of the transceiver's unique identificataon code broadcast by the satellite, the transceiver will transmit its identification code back to the satellite ground station via the satellite transponder. The round strip response time is used to calculate the range from the satellite to the transceiver. The Doppler shift of the received signal, due to the satellite motion of a satellite in non-geostationary orbit, is used to calculate the angle-of-arrival at the satellite.
