| Abstract: | This paper uses R-T-S smoothing technique to test and evaluate GPS/DR integrated navigation system via post processing of navigation data. The semi-physical simulation is implemented on computer with the static test data given by GPS and DR. The results obtained show that significant improvements can be obtained by smoothing the data. Not only the precision is improved greatly but also the curves obtained by R-T-S smoother changes more gently than that obtained by Kalman filter. |
