摘要
Abstract
The dead reckoning trajectory and real trajectory are similar, and they are in line with the principle of similarity. The similarity is proved by Graphic method used to derive the position correction formula. The position correction technology is applied to the initial calibration of odometer, and the measured data proves that the calibrated heading installation deviation angle, pitch installation deviation angle and the scale factor error of odometer decrease significantly. The position correction technology and GPS are assembled as GPS / DR integrated navigation, and the simulation by Matlab shows that the heading error can be limited to the range of less than 3. 6' in the long-distance navigation of vehicle. The correction technique has a high practical value.关键词
