Advances in single-beacon one-way-travel-time acoustic navigation for underwater vehicles
TL;DR: This paper reports the formulation and evaluation of a centralized extended Kalman filter designed for a novel navigation system for underwater vehicles that employs Doppler sonar, depth sensors, synchronous clocks, and acoustic modems to achieve simultaneous acoustic communication and navigation.
Journal ArticleDOI
Decentralized Extended Information Filter for Single-Beacon Cooperative Acoustic Navigation: Theory and Experiments
TL;DR: It is shown that at the instance of each range measurement update, the DEIF algorithm yields identical results for the current vehicle state estimate as the corresponding centralized extended information filter (CEIF), which fully tracks the joint probability distribution between the server and client.
Proceedings ArticleDOI
Preliminary deep water results in single-beacon one-way-travel-time acoustic navigation for underwater vehicles
TL;DR: The development and experimental evaluation of a novel navigation system for underwater vehicles that employs Doppler sonar, synchronous clocks, and acoustic modems to achieve simultaneous acoustic communication and navigation and forms the basis for a vehicle-based real-time navigation system.
