GPS RECEIVER FOR TRACKING A GPS SIGNAL IN REAL TIME THROUGH A SOFTWARE TYPE GPS PROCESSOR MODULE

摘要

PURPOSE: A GPS receiver for tracking a GPS signal in real time through a software type GPS processor module is provided to improve a dynamic property of a signal and tracking accuracy through an FFT-IFFT based signal obtaining module.;CONSTITUTION: An RF front end unit(100) downwardly converts an RF signal received through a GPS antenna into an intermediate frequency signal. A correlator(200) extracts navigation data through the process of the intermediate frequency signal and generates a raw measured value. A software type GPS process module(300) charges user interface and estimates navigation solution by using the output data of the correlator.;COPYRIGHT KIPO 2011
