Assessment of a Shallow Water Area in the Tagus Estuary Using Unmanned Underwater Vehicle (or AUV's), Vector-Sensors, Unmanned Surface Vehicles, and Hexacopters – REX'17

This paper describes the work done during REX'17, an exercise conducted by the Portuguese Navy in cooperation with Portuguese universities to test, demonstrate, and develop research projects, and to approach the academic and military communities. This year the exercise took place in the Tagus river estuary, and its main aim was to assess shallow water areas, regarding bottom, and acoustic characteristics. The experiments involved testing of vector sensors development at the University of Algarve, an UUV developed by INESC-TEC, a marsupial robotic team of a USV and a hexacopter capable of landing on water developed by the New University of Lisbon (Nova), and a hydrophone network used by the Portuguese Naval Academy.
