Combined Positioning Method of Port AGV based on Beidou Difference and Inertial Navigation Technology

With the development of port construction and Automated Terminals, the AGV positioning technology of current ports is single and the perception and understanding of the external environment is insufficient, which directly affecting the operation efficiency of ports. The combined positioning method of Beidou difference and inertial navigation of port AGV is studied, which combining with the actual environment of ports, kalman filter and weighted average algorithm are used to fuse positioning data, and good fusion results are achieved. The combined positioning experiment is designed, and the experimental results show that the precision of the combined positioning method is better than the Beidou difference and inertial navigation alone, which can meet the high precision positioning requirements of the AGV in ports. The feasibility of the combined positioning method is demonstrated, and the real-time high precision positioning of port AGV is realized.
