摘要
文中应用R-T-S平滑算法通过事后处理导航参数来检测和评估GPS/DR组合导航系统的精度,利用GPS和DR提供的静态测试数据通过计算机进行了半物理仿真。结果表明R-T-S平滑算法能够有效地检验和评估GPS/DR组合导航系统的精度,是一种有效的事后处理方法。
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.
