On 8-21 July 2015 CMRE (Centre for Maritime Research and Experimentation) scientists and engineers were on board the Portuguese Navy vessel NRP Gago Coutinho in the Azores archipelago (Portugal), around the Island of Faial for the REP15 experiment.
REP15 stands for Recognized Environmental Picture (REP) 2015. REP15 is a joint exercise of CMRE, the Portuguese Navy, the University of Porto and the University of Azores. The sea trial included several different types of Autonomous Surface Vessels (ASVs), Autonomous Underwater Vehicles (AUVs) and Unmanned Aerial Vehicles (UAVs) equipped with different sensors and acoustic payloads.
REP15 aimed to test networks of unmanned maritime vehicles that can be used in scenarios of mine countermeasures, maritime security, environmental knowledge, search and rescue, and maritime law enforcement.
Through REP15, all the partners enabled collaborative research to increase interoperability, underwater communications and networking capabilities, automation and cooperation of unmanned underwater, surface and aerial vehicles.
CMRE research in REP15 was focused on acoustic underwater communications. CMRE scientists experimented networking and equipment capabilities, including Wave Gliders being tested as autonomous gateways and AUVs exchanging data in an underwater network. The trial included experimentation with the capabilities of JANUS, an underwater digital communication protocol, developed at CMRE, that is currently being promoted in the maritime industry.
