N2 - For the GNSS receiver, when the satellite navigation signal is weak, the traditional tracking accuracy of GNSS receiver tracking loops will decline sharply which will lead to the deterioration of the Carrier frequency error. Aiming at improving the Velocity Determination accuracy of GNSS receiver, we propose the GNSS Precise Velocity Determination Algorithm Based on Chaotic Oscillator. The proposed algorithm, on the basis of the traditional tracking loop, has greatly improved the accuracy of the original Doppler frequency by introducing the Chaotic Oscillator to estimate the carrier frequency. The simulation proves that, under a certain dynamic range, the velocity determination accuracy of the GNSS receiver, in the aid of the new algorithm, has been greatly improved.
