ABSTRACT:
A system and method for determining one or more satellites in view of a wireless device. A request for satellite assistance data may be received from a requesting entity and a reference location determined as a function of the request. A set of satellites may be determined as a function of the reference location. Subsequent cached information may be determined for each satellite in the set of satellites if cached information already existing for each satellite in the set of satellites has been cached for greater than a predetermined time period. This subsequent cached information may then replace the previously existing cached information for the reference location. One or more satellites in view of the wireless device may then be determined as a function of either the subsequent cached information or previously existing cached information, and assistance data may be provided to the requesting entity to determine an estimated location of the wireless device.
