| Abstract: | Through analyzing the properties of vehicle GPS navigation signal's observation gross error and random noise,a new gross error detecting algorithm and de-noising algorithm of vehicle GPS navigation signal is presented based on wavelet transformation.Data emulation calculation shows that this algorithm can overcome the gross error influence on filtering precision by comparing with the kalman filtering algorithm,and the strict mathematical model isn't essential for the algorithms. |
