ABSTRACT:
An apparatus and method is provided for increasing GPS reception sensitivity in a mobile terminal having a mobile-based GPS positioning function. A GPS receiver in the mobile terminal generates SA data by using basic information about GPS satellites and system time. Here, the SA data is a replica of the total information bits of navigation data. The GPS receiver then correlates a PRN code with a GPS signal and coherent-integrating the correlation result by using the SA data. It calculates a position solution of the mobile terminal by using the integrated samples.
