发明名称 Method and system for using altitude information in a satellite positioning system
摘要 <p>A method and apparatus for determining a position of a mobile satellite positioning system (SPS) receiver is described. A position of a mobile satellite positioning system (SPS) receiver is determined by initially determining a plurality of satellite pseudoranges between said mobile SPS receiver and a corresponding plurality of satellites. Then, at least one non-satellite pseudomeasurement is determined. Finally, a condition of at least one of said plurality of satellite pseudoranges is determined.</p>
