| Abstract: | In order to improve positioning accuracy of the GPS/DR integrated positioning system, map matching algorithm is frequently used to modify the positioning error. In this paper, a fuzzy logic-based correction algorithm of navigation and positioning data was introduced, which was able to correct the Joint Kalman filter output of GPS/DR positioning data. The error could be effectively reduced by fuzzy logic-based correction algorithm of navigation and positioning data. Thus, the results of the MATLAB Simulation show that the algorithm can effectively reduce the error, and improve the positioning accuracy of Integrated Positioning Systems and the quality of tracking services. |
