Abstract
A system and method for determining a location of a wireless device in a communications network. A request for satellite assistance data may be received from a requesting entity, and a reference location determined as a function of the request. One or more characterizing attributes may be identified as a function of the reference location, and a set of satellites determined as a function of the reference location. It may also be determined whether more than one set of signal measurements should be acquired from one or more satellites in the set of satellites as a function of the identified one or more characterizing attributes. The one or more sets of signal measurements may be acquired, and a location of the wireless device determined from the acquired measurements.
