农机车载GPS和DR组合导航系统定位方法
GPS/DR Integrated Navigation Positioning Method for Agricultural Machinery
摘要
Abstract
In order to improve positioning accuracy of GPS/DR integrated navigation, the fuzzy adaptive Kalman filter method was analyzed. Experiment was carried out on the modified agricultural machinery. Experiment results showed that the fuzzy adaptive Kalman filtering could inhibit the influence of unusual values on the localization precision of the system, and the system positioning accuracy of the proposed method was better than single GPS. The average positioning error of the x and y directions were 0. 13 m and 0. 20 m by using the fuzzy adaptive Kalman filter. Positioning curves was smoother after filer.关键词
