An Integrated Navigation and Localization System
2021 IEEE International Conference on Smart Internet of Things (SmartIoT), 2021Navigation and localization technique is a critical part of an autonomous underwater vehicle (AUV). It provides critical position information, and determines the efficiency and accuracy of underwater tasks. To improve the accuracy and reliability of the navigation and localization system, we proposed an integrated navigation and localization system ...
