Abstract (in Japanese) (See Japanese page) 
(in English) In order to extend the number of which population are concerned with the underwater observation, the authors focus on the free-fall type of underwater exploration system.
Because the free-fall type systems are realized at low cost and are easy to operate.
The underwater position is required for exploration strongly although it is difficult to determine the underwater position of the free-fall type due to tidal current and so on.
Until now, we have developed a whole underwater circumferential observation system that is named Gyogyotto Camera.
The camera system consists of the glass sphere which can be submarined at 7800m of sea depth.
The observation system achieves the underwater circumferential video successfully,
In this report, the feasibility of the underwater positioning is studied using a micro electro mechanical system (MEMS) for an inertia measurement unit (IMU) inside the developed camera system.
The accuracy of the underwater positioning estimation is investigated while the camera system off the coast of Oki island practically is submerged.
