1. A system for estimating the terrestrial position of a vehicle, comprising:
- means for receiving electromagnetic signals from a plurality of sources and responsively producing respective ranges from each of said sources to said vehicle and respective positions of each of said sources;
means for projecting the position of one of said sources to the opposite side of the Earth with respect to the center of the Earth and responsively determining a projected position;
means for receiving said projected position and responsively producing a projected range;
means for receiving said projected range and the ranges from the other sources and responsively determining the position of said vehicle.

Abstract
The present invention includes a system for estimating the terrestrial position of a vehicle. The system receives electromagnetic signals from a plurality of sources and responsively producing respective ranges from each of said sources to said vehicle and respective positions of each of said sources. The system projects the position of one of said sources to the opposite side of the Earth and responsively determining a projected position and a projected range. The vehicle'"'"'s position is determined as a function of said ranges and positions.
