1. A method for estimating a position of receiver, wherein the method comprises:
- extracting information from a first ranging signal received from a first transmitter;
extracting information from a second ranging signal received from a second transmitter;
determining a first location of the first transmitter;
determining a second location of the second transmitter, wherein the first location and the second location are separated by no more than 100 meters; and
determining an estimated position of the receiver based on one or more relationships between the information extracted from the first and second ranging signals and information corresponding to the first and second locations.
