Abstract  Abstract

The invention concerns a method to determine approximate Doppler to assist a mobile system (375) having an SPS receiver (376) and a communication transceiver (378) in communication with a cell site of a cellular communication system, the method comprising: - determining an approximate location of the SPS receiver, said approximate location being determined using: o a location of the cell site in communication with the mobile system or o a location of a cellular service area including the cell site; - determining an approximate Doppler for at least one SPS satellite relative to said SPS receiver, said approximate Doppler being determined based on said approximate location; - transmitting said approximate Doppler to the mobile system to be used by said SPS receiver.
