Method and apparatus for estimating position utilizing GPS satellite signal
First Claim
1. A method of determining position using a global position satellite (GPS) signal, comprising:
- receiving at a receiver a first GPS signal from a first GPS satellite at a first position of the first GPS satellite;
receiving at the receiver a second GPS signal from the first GPS satellite at a second position of the first GPS satellite; and
determining a position of the receiver using the first and second GPS signals.

Abstract
The invention is directed to an apparatus and method for determining or estimating position using GPS signals. The system includes a receiver such as a GPS receiver for receiving GPS signals and a processor for determining position from the received GPS signals. The receiver receives a first GPS signal from a first GPS satellite at a first position of the first GPS satellite. A second GPS signal is received by the receiver from the first GPS satellite at a second position of the first GPS satellite. Position of the receiver is determined using the first and second GPS signals. Time differences between the two signals can be determined and used in calculating position.
