Abstract:
1. A method, comprising: determining an ordered set of SPS satellites in view of a location of a cell of a cellular communication system at a given time, wherein an order of SPS satellites in the ordered set is determined in a manner selected from the group consisting of, minimizing a geometric dilution of precision (GDOP), minimizing a position dilution of precision (PDOP), minimizing a horizontal dilution of precision (HDOP), providing a position solution which uses SPS satellites having a desired geometry relative to one another, providing a position solution which uses SPS satellites having a desired geometry relative to the mobile SPS receiver, determining a probability of SPS satellite signal acquisition, determining an estimate of measurement quality from the ordered set of SPS satellites, providing an optimal geometric trilateration solution, and determining a user defined selection criteria; and wherein a mobile SPS receiver located within the cell of the cellular communication system may receive the ordered set of SPS satellites, and transmitting the ordered set of SPS satellites.
