Events

As refered in a previous post REP14 - Atlantic stands for Recognized Environmental Picture (REP) Atlantic 2014, and was a joint exercise of the Portuguese Navy, the NATO Centre for Maritime Research and Experimentation (CMRE), and the University of Porto, through the Laboratório de Sistemas e Tecnologia Subaquática (LSTS).

This exercise was conducted at the Lisbon naval base and of the coasts of Sesimbra and Sines, Portugal. The exercise was focused on evaluating, testing, and demonstrating tools and technologies for persistent operations of collaborative underwater, surface and air vehicles in mine hunting, oceanography, expeditionary hydrography, search and rescue, environmental knowledge, maritime security and harbour protection.

Supporting these operations, were the ships NRP Pegaso, NRP Auriga, and the submarine NRP Arpão from the Portuguese Navy, and the NATO Research Vessel Alliance.
Some of the highlights of the experiment were:

Inter-operated underwater and radio communication networks were used for multi-vehicle coordination and control with support for disruptive tolerant networking
Long range AUVs provided support for 24+ operations
Deliberative on-board planning capabilities provide unprecedented levels of autonomy.
Deliberative planning techniques were also used to support coordinated planning and execution control of multiple vehicles
Unmanned air vehicles were used as communication relays and also for tasking autonomous underwater vehicles
USBL techniques were used for localization and tracking of multiple targets
Launch and recovery of autonomous underwater vehicles from NRP Arpão was done at sea as a first step towards automating the launch and recovery process from manned submarines.

Other relevant aspects of this experiment was the number of hours of operation, and area covered. The tables below provide a good overview of the capacities and robustness of our AUV's.

Week 3 - Aboard the Alliance
AUV	Distance Traveled	Hours of Operation
Noptilus-2	53.41 Km	15h21m7s
Noptilus-3	127.73 km	43h15m37s
Total	181.15 km	-

The participants of REP14-Atlantic included the University of Rome (Italy), the Naval Undersea Warfare Center (USA), the College of Charleston (USA), the Royal Institute of Technology and the companies Evologics (Germany) and Oceanscan (Portugal).

Exercises

REP14-Atlantic stands for Recognized Environmental Picture (REP) Atlantic 2014. REP14-Atlantic is a joint exercise of the Portuguese Navy, the NATO Centre for Maritime Research and Experimentation (CMRE) and the Faculty of Engineering of University of Porto (FEUP).
REP14-Atlantic is a large experiment to be conducted in the Lisbon Naval Base and off the coasts of Sesimbra and Sines, in Portugal, from 7 to 24 July 2014. It includes several Autonomous Surface Vessels (ASVs), Autonomous Underwater Vehicles (AUVs) and Unmanned Aerial Vehicles (UAVs) equipped with different sensors and acoustic payloads, which will be deployed from Portuguese Navy ships NRP (“Navio da Republica Portuguesa” i.e. Ship of the Portuguese Republic) Pégaso, NRP Auriga, submarine NRP Arpão and the NATO Research Vessel Alliance.
