Abstract
A method of improving the reception performance of a network-aided GPS (Global Positioning System) receiver is disclosed. It is determined whether the present time is feasible for TLM/HOW coherent integration, based on present CDMA/GPS information. When the TLM/HOW coherent integration is immediately available, a GPS signal acquisition search is performed using the TLM/HOW coherent integration. Then, it is determined whether the signal acquisition search is successful. If the signal acquisition search has failed, then there is a request for navigation data bits to a base station, which increases a coherent integration period.
