Patent ID: 7446703

Claim:
An apparatus for receiving global positioning system (GPS) signals in a mobile terminal, comprising: a first radio frequency (RF) receiver for receiving a first RF signal comprising basic information about a GPS satellite over a mobile communication network; a first baseband processor for acquiring the basic information and system time of the mobile communication network based on the output of the first RF receiver; a second RF receiver for receiving a second RF signal comprising navigation data from the GPS satellite; a navigation data bit estimator for generating sensitivity assistance (SA) data by using the basic information and the system time, the SA data being a replica of the total information bits of the navigation data; a second baseband processor for generating integrated samples by correlating a pseudo-random noise (PRN) code with the second RF signal and coherent-integrating the correlation result by using the SA data; and a signal detector for calculating a position solution of the mobile terminal by using the integrated samples received from the second baseband processor.
