Autonomous Underwater Vehicle Navigation

IEEE Journal of Oceanic Engineering, 2010
This paper considers the vehicle navigation problem for an autonomous underwater vehicle (AUV) with six degrees of freedom. We approach this problem using an error state formulation of the Kalman filter. Integration of the vehicle's high-rate inertial measurement unit's (IMU's) accelerometers and gyros allow time propagation while other sensors provide

Avoidance of underwater cliffs for autonomous underwater vehicles

IEEE/RSJ International Conference on Intelligent Robots and System, 2003
This paper introduces a method aiming to allow underactuated autonomous underwater vehicles navigating in an unknown environment to avoid underwater cliffs. Three electro-acoustic transducers situated in the front part of the vehicle provide bathymetric data.

An autonomous underwater vehicle for competition

2012 First National Conference for Engineering Sciences (FNCES 2012), 2012
The research of this paper was derived from the small autonomous underwater vehicle (AUV)Raider well performed in the 15th International Underwater Vehicle Competition (IAUVC),San Diego. In order to improve the performance of underwater vehicle, the control system of performance motion played an important role on autonomous underwater vehicles stable ...

Autonomous Underwater Vehicle Navigation

2016
This chapter surveys the problem of navigation for autonomous underwater vehicles (AUV s). Navigation is critical for the safety and effectiveness of AUV missions. The unavailability of global positioning system (GPS ) underwater makes AUV navigation a challenging research problem.

Autonomous Underwater Vehicle Control

2019 Innovations in Power and Advanced Computing Technologies (i-PACT), 2019
Earth, the third planet from the sun is the only planet on which life is known to exist. Seventy percent of the earth is covered by oceans. These oceans have been playing a very crucial role in transporting of goods even before the road. At the same time it cannot be ignored the possibilities of the negative role of the oceans- a very serious threat to

From autonomous underwater vehicles (AUVs) to supervised underwater vehicles (SUVs)

Oceans '97. MTS/IEEE Conference Proceedings, 2002
The past fifteen years have seen the development of a new family of unmanned underwater vehicles without umbilical. Initially, those vehicles were operated in the direct vicinity of the mother-ship. With the increase in range and reliability, users are now willing to operate without support vessels.
