Design of Underwater Passive Navigation Simulation System Based on Information Fusion

摘要

This paper makes full use of information obtained by various kinds of marine geographical features sensors according to the characteristics of underwater autonomous navigation system (gravity navigation, terrain-aided navigation, magnetic navigation) for data preprocessing, algorithm analysis, performance evaluation, intelligent data fusion, and then complete modular simulation of underwater passive navigation system design, providing practical design and technical line for the underwater passive navigation system for the further study. The result shows that using underwater terrain matching aided navigation can effectively correct inertial navigation system (INS) errors and get the design demands, thereby provide reliable technical support for precise navigation in real marine environment.
