Abstract

Abstract The submarine vehicle is connected to a surface operating station by means of a control tether. The control tether contains conduits supplying hydraulic fluid under pressure as well as electrical power to the submarine vehicle. The submarine vehicle is controlled in depth by means of a buoyancy chamber comprising two telescoping chambers which are displaced with respect to each other by means of an internal motor means. A support system attached to the buoyancy chamber provides mounting for a camera to view the underwater location surrounding the submarine vehicle. A combination navigation instrument is mounted on the submarine vehicle and cooperates with the camera to provide an indication of heading and inclination of the vehicle as well as a number of turns the vehicle has made since its launch.
