Future Autonomous Underwater Vehicle system (AUV)

Next Generation Power System


Prototype of a small, high-efficiency Three-less (HETL) fuel cell
  • Technology for a new type of fuel-cell battery has been developed to allow long-range navigation in the deep sea without a fuel supply.
  • In 2010, prototype tests were run on a small, high-efficiency Three-less (HETL) fuel cell.

Underwater Acoustic Communication System

  • An underwater acoustic communication system has been developed to actualize transmitting picture signals and control signals between a vehicle and it’s support vessel.
  • In 2010, test of long-range transmission using Time Reversal Acoustic communication and short-range high-capacity transmission at sea were conducted.

Long range-transmission using Time Reversal Acoustic communication

Detailed Investigation Systems


GOSEIKAIKO sonar installed in URASHIMA
  • Acoustic sonar systems to survey topography and geology of the ocean floor have been developed.
  • In 2010, the Goseikaiko sonar system was installed on the URASHIMA, and performance improvement tests were conducted in the sea.

Control System


Multi-CPU Control System
  • This control system is composed of multiple CPUs, and the system load can be distributed because each one is used separately according to the functions of the underwater vehicle.
  • In 2010, this control system was installed on the MR-X1, and sea trials were conducted to verify its utility.

High-performance Navigation System


Prototype of compact-size inertial navigation system
  • An inertial navigation system has been developed to allow autonomous navigation in the sea, where GPS doesn’t work.
  • In 2010, performance tests of compact-size inertial navigation system were conducted in the sea.
