Abstract
A system and method are disclosed for estimating the location of a satellite terminal. A plurality of gateways having known locations are identified. A plurality of reference terminals associated with the gateways are identified, wherein a reference round-trip time (RTT) for signals between each reference terminal and the gateways via the satellite is known. The RTT is used to estimate the satellite's position over a plurality of time instances. The location of a selected terminal associated with a selected gateway is estimated based, in part, on the estimated satellite positions and an RTT for signals between the selected terminal and the selected gateway.
