METHOD AND APPARATUS FOR AIDING POSITIONING OF A SATELLITE POSITIONING SYSTEM RECEIVER

摘要

A satellite positioning system (SPS) receiver (104) operates according to a method (200) having the steps of measuring (201) a distance between the SPS receiver and a transmission source (301) according to a radio frequency (RF) signal transmitted by the transmission source, calculating (212) an approximate location on Earth from the distance and a location of the transmission source, and determining (214) a location fix of the SPS receiver on Earth using the approximate location. Other method and apparatus embodiments are disclosed.
