An integrated navigation system for a long range AUV

Abstract: Presents the basic concepts of an integrated navigation system devised for a long range AUV which has to reach distant mission points while the currents can be only roughly predicted and details on the sea bed are locally known The system includes several basic functions that are under the control of an execution monitor in order to perform re-planning when abnormal conditions are encountered

Construction of an underwater vehicle

Abstract: This patent application describesa new method for constructing an Autonomous Underwater Vehicle (AUV). The construction is firstly based on modules that each houses a certain function, sensor or equipment of the AUV. Secondly the modular construction also covers the software that is modular and based on mimickling the crew of a research vessel. Thus there are software modules that handle the different types of steering of the AUV, a captain that oversees the general operation and mission of the AUV, a scientific mission leader, scientists that handle individual sensors and the processing of their measurements, an engineer that oversees the functions of the mechanical units etc.

Implementation of an underwater acoustic network using multiple heterogeneous vehicles

Abstract: In this paper we investigate the creation of an heterogeneous underwater network with static and mobile assets cooperating together in coordinated missions using acoustic links. Each underwater device combines communication, networking, and sensing capabilities, and cooperates with the other devices to accomplish a given task. The flexibility and capability of the proposed system allows to overcome the limitations of commercial solutions currently available in the market which typically focus on point to point communications. SUNSET framework has been used to provide acoustic communication and networking capabilities to AUVs, ASVs and moored systems developed by the Oceans Systems Group, at the University of Porto, in Portugal. New solutions have been developed and tested allowing to combine together acoustic data transmission and ranging estimation, to control the underwater nodes acoustically and to instruct the vehicles on keeping a given formation using acoustic links. To validate the proposed approach several experiments with increasing complexity have been conducted at the laboratory and in the field. The experimental results confirm the validity, efficiency and reliability of the proposed solution opening to several possibilities for future developments.

Development of autonomous underwater vehicles in Japan

Abstract: In the hope of expanding underwater observation and research, the Institute of Industrial Science (IIS) at the University of Tokyo started extensive R&D on autonomous underwater vehicle (AUV) in 1984. IIS has constructed nine vehicles, including three ocean-going vehicles, one lake survey vehicle and various testbed vehicles. The R-One Robot is equipped with a closed-cycle diesel engine system and it successfully completed a 12-h operation of long-range autonomous diving in the Pacific Ocean in 1998. Utilizing the testbed robots, many intelligent systems, especially those for underwater vision systems, have been developed. The success of these AUVs at the IIS has led to the establishment of the 'Underwater Technology Research Center' which opened on 1 April 1999. This new center also plans to collaborate both nationally and internationally with other facilities for further R&D of AUVs and other new underwater observation technologies.
