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.
