Most Autonomous Underwater Vehicles (AUVs) mount Doppler sensors to navigate precisely underwater, where the Global Positioning System (GPS) is unavailable. These sensors -aside of providing accurate AUV velocity with ...

Fish farming activities are a relevant economic resource in coastal waters, which have grown in a significant way in recent decades, often with deleterious environmental effects. The sustainability of the activity requires ...

Underwater tanks for calibration are commonly used for transducer calibration and acoustic characterization. However, low frequency range is limited by tank dimensions and wall proximity to sound source. A possible ...

Hydrocarbons are one of the most important toxics in the oceans. Their presence may cause the death of organisms. They even can affect to the human beings, when they consume products that have been in contact with the ...

This article is about the development of the equations of the movement in 6 DOF of AUV (Autonomous Underwater Vehicle) SIRENA carried out by students of UPCT. As it is a pre-programmed submersible, one of the main targets ...

The increasing demand for underwater robotic intervention systems around the world in several application domains requires of more versatile and inexpensive systems. One example of such applications is the archaeology, ...

The use of radionuclide tracers to determine the submarine groundwater discharges has been used widely but in areas highly anthropized as the Mar Menor surface water tributaries can carry high concentration of Radon, ...

A model of a hybrid system with renewable energy for electric propulsion in boats in which energy generated by photovoltaic panels and hydrogenerator is stored in the main battery which exerts its function as central ...

This paper introduces an unmanned aircraft vehicle (multicopter) for coastal applications. This vehicle has surveillance purposes, and it is configured with routes in such a way that the vehicle is capable of displaying ...

This paper presents an overview of coordinated project MISSION-SICUVA, and the results achieved at its recent completion. A prototype of UUV has been built with an orientation to oceanographic research and test of new ...

In this paper a new electronic control system for unmanned underwater vehicles is presented. This control system is characterized by a distribution in control over two network of type CANBus and Ethernet. This new ...

Ever-growing attention has been given to the monitoring and inspection of underwater man-made structures for scientific and technical purposes. However, most of the related tasks are still involving the use of scuba ...
