Abstract
Autonomous underwater vehicles and systems are provided with fast stabilization and fine attitude control with a constant and high rotational speed flying wheel to rotate the vehicle's body with respect to its core and optionally a combination of reaction masses used in three perpendicular axes. The gimbal and the reaction mass inertial systems are used for fast response to any angular or linear disturbance coming from the ocean current or waves. When equipped for optical communications, the vehicle has an optical receiver and transmitter and controller that provides three levels of attitude stabilization: gimbal and the reaction mass inertial systems; isolated movable platform and fine optical beam steering for targeting the laser beam from the transmitter. The ability to maintain precise positioning allows multiple vehicles to be optically linked.
