Modeling and Realization of GPS IF Signal

    Graphical Abstract
    • Abstract
  • A GPS IF signal computer-aided simulation method is proposed.The carrier Doppler frequency and the total propagation delay time can be modeled or calculated with the input GPS satellite ephemeris file.The simulated GPS IF signal is output to a text file for GPS software receiver post-processing and analyzing.The simulated GPS IF signal spectrum is compared with the received real one.The validity of the simulation result is verificated.
