Methods and apparatuses for using assistance data relating to satellite position systems
First Claim
1. A method for providing information to a satellite positioning system (SPS) receiver, said method comprising:
- determining an ordered set of SPS satellites in view of a mobile SPS receiver having an approximate location, the ordered set based on the approximate location which is determined from at least one of a location within a cellular service area which includes a cellular transmission site in cellular communication with a communication system coupled to the mobile SPS receiver or a representative location associated with the cellular transmission site, wherein an order of SPS satellites in the ordered set is based on a location of at least some of the SPS satellites.

Abstract
Methods and apparatuses to obtain an ordered set of satellite positioning system (SPS) satellites, in view of a mobile SPS receiver, via one or two-way communication with the mobile SPS receiver. The mobile SPS receiver receives, in one embodiment, an ordered set of SPS satellites from a cellular transmission site. The ordered set of satellites are those in view of the mobile SPS receiver at a given time; such that the mobile SPS receiver may search for the SPS satellites according to an order of the ordered set of SPS satellites. The order of the ordered set may be obtained by various methods one of which is by minimizing the geometric dilution of precision (GDOP) Satellite; health data may be included in the transmission.
