| Outline of Final Research Achievements |
In this study, a new navigation method for underwater vehicle was proposed. In the method, inverse super short baseline (ISSBL), in which acoustic signal transmitted from a mother ship is received with an receiver array equipped on the vehicle and direction of arrival of the signal is measuired, and acoustic data transmission of information of ship's position are adopted.
Ocean experiments using a experimental device moored on the seabed or equipped on a underwater vehicle were carried out. Depth of experimental area was up to 2,000 meters. As result, it was found that the proposed method is enough feasible and condidered merits of the method is valid. Furthermore, error of estimation of the ship's position in the position calculation becomes effective. In the future, a prototype device for actural operation will be designed based on the result and knowredge from this study and developed.
