| Abstract: | This paper demonstrates the modelling of GPS SA error. static position error samples recorded with TANS-2 receiver are analysed in frequency domain via FFT to ger the SA power spectrum, and the SA stationary linear model is obtained approximately via least-squares fit.The approximate model is used in the simulation of the vehicle integrated navigation system and the results show its effectiveness. |
