ABSTRACT:
A system and method for estimating the location of a wireless device. A set of satellites may be determined as a function of an approximate area in which the wireless device is located. Assistance data is transmitted to the device including information from the set of satellites, and a location of the device may be estimated from the information where the assistance data prevents the wireless device from searching for signals from one or more satellites in the set of satellites. The one or more satellites may be an operable satellite but signals therefrom cannot be measured or acquired by the wireless device.
