METHOD AND APPARATUS FOR MEASUREMENT PROCESSING OF SATELLITE POSITIONING SYSTEM (SPS) SIGNALS

摘要

A method and apparatus for measurement processing of Satellite Positioning System (SPS) signals. A plurality of SPS signals are received. The signal environment is characterized to produce signal environment data. Times of arrival of respective satellite signals from the plurality of satellites are measured. Data representing measured times of arrival are processes to produce a set of times of arrival from which a location fix for a SPS receiver is calculated.
