Abstract :
This paper proposes two modifications in tracking high dynamic GNSS signals with extended Kalman filter. One is used to estimate the amplitude of signals better, while the other is used to eliminate the phase error of correlator outputs. Simul-ation results show that the variance of estimation and BER of navigation data are both reduced highly.
