AIDING LOCATION DETERMINATIONS IN SATELLITE POSITIONING SYSTEM RECEIVERS |
摘要 |
<p>A method for locating a satellite positioning system receiver, for example, a satellite positioning system enabled wireless communications device in cellular network, including obtaining a coarse position and/or a time estimate (210), and computing a satellite positioning system based position and/or time solution (240) that is constrained by uncertainty information associated with the coarse position and/or a time estimate. The uncertainty constraints may also be used to identify erroneous measurements used to compute the position solution.</p> |
