Jie Wang, Xue Yuan Lin, Li Long Guo · Applied Mechanics and Materials · 2013
According to the characteristics of the GPS receiver, this paper introduces an improved GPS positioning system filtering algorithm. Firstly, this paper establishes the state equation of the system according to the motor carrier's "current" statistical model, and then we establishes the measurement equation of the system based on the characteristics that GPS receiver can output the location and speed information, and lastly we get a standard Kalman filter algorithm model and a detailed description of the derivation of the algorithm. Algorithm simulation results show that the improved algorithm can greatly improve accuracy.
