During processing, visualization and analysis of multi-variable oceanographic data sets from an AUV it can be challenging to both maintain overview and pay attention to detail. We here describe a software system intended to bridge this gap and discuss its application on ADCP and CTD data recently acquired by the HUGIN 1000 AUV in the Barents Sea. The software, ANCOR II, features interactive graphics...
This paper reports the theory and implementation of a decentralized navigation system that enables simultaneous single-beacon navigation of multiple underwater vehicles. In single-beacon navigation, each vehicle uses ranges from a single, moving reference beacon in addition to its own inertial navigation sensors to perform absolute localization and navigation. In this implementation the vehicles perform...
Over the past decades, the design and development of mission based Autonomous Underwater Vehicle (AUV) continues to challenge researchers. Although AUV technology has matured and commercial systems have appeared in the market, a generic yet robust AUV command and control (C2) system still remains a key research area. This paper presents a command and control system architecture for modular AUVs. We...
Today a large number of autonomous underwater vehicles (AUVs) are evaluated or operated all over the world. Most of them use their own control systems created by the vehicle's manufacturer or scientists of different research areas. The Fraunhofer Application Center System Technology currently owns three underwater vehicles (both AUVs and remotely operated vehicles, ROVs), a forth is under development...
Today, due to the current state-of-the-art of embedded systems, underwater robotic vehicles are limited in both, their autonomy and capabilities. In order to increase their utility it is advantageous to run multiple vehicles at the same time whereby each vehicle serves as individual node in an underwater network. In this context a group of leading European vehicle manufacturers and researchers set...
This paper presents a platform-independent acoustic communication (Acomms) system that enables multiple nodes (any combination of underwater vehicles, surface ships, and fixed beacons) to simultaneously exchange data and calculate inter-node ranges with O(1m) accuracy. The Acomms system supports two types of communications: standard asynchronous acoustic communication and synchronous communication,...
In this paper, we discuss the design aspects and the development of the MARES AUV, a 1.5 m long vehicle, weighting 32 kg, designed and built at the University of Porto, Portugal. This vehicle is highly maneuverable, with the ability to move in the vertical plane, controlling pitch and vertical velocity; forward velocity can also be determined, anywhere between 0 and 2 m/s. MARES can easily integrate...
