Method for reducing the search displacements of codes in a GPS ReceiverWhich is integrated to a Mobile Station includes a transceiver operating in a wireless network and System for Aligning the time base of the mobile station.

摘要

A method and a system which improves the acquisition of the signal in the receiver of a Global Positioning System (GPS) to provide information that focuses on the search for AcquisitionL receptor.In particular,The Invention relates to a case where a GPS Receiver is integrated with a transceiver that is capable of communicating with a Mobile Network PCs through the Air Interface of theNetwork. The Standard information provided by the network is used to assist the receiver Integrated and to improve its Sensitivity and latency.The result of this improvement is that the receiver can acquire Satellites quickly and calculate their positions in environments where conventional Autonomous GPS receiversCan.This improved performance is very important for the application of the location of emergencySince the use can have expectations of security personnel in a wide variety of situations.Also, the rapid Acquisition reduces energy consumption, which is very important for the battery Apparatus using such combined GPS and cellular Technologies.
