摘 要：The application of distributed multi-sensor information fusion technology in accurate positioning of Underwater Vehicle was introduced in this paper.According to the system structure of Distributed multi-sensor in an AUV "T1",this article establishes the Kalman filtering mathematical model,accomplishes the fusion algorithm based on Kalman filtering and a numerical simulation.The experimental result shows that the application of fusion algorithm based on Kalman filtering can avoid the limitations of a single sensor,reduce its uncertainty impact and increase the confidence level of data.
