Autonomous unmanned underwater vehicles
The autonomous unmanned underwater vehicle (AUV) is an automatic self-propelled platform of research instrumentation which is able to dive into the preset area of the ocean at a depth up to 6000 m, move along the programmed trajectory, perform necessary operations and at the end of program return to the support vessel or base point.
The AUV operates under water independently without the umbilical. Transmission of instructions on-board the vehicle and video information back is accomplished by means of acoustic communication link. The acoustic positioning system together with integrated on-board navigation system allow to determine continually the vehicle location whereas an operator of support vessel is able to track the trajectory of the vehicle motion in real time. The time of AUV continuous operation under water depends upon the vehicle design and type of power source and may amount from units to several tens of hours. The instruments......
