.“Outside the university, we have secured the support of another government organization, which has been extremely productive and beneficial,” Armand said. “Since 2016, the Navy Research Institute (IPqM) has supported us in the development of our software. Our work with the Acoustic Systems Group has developed the algorithms for the acoustic signal processing, implementing the beam forming algorithm for our AUV to find pings in the competition. This experience provided an unparalleled learning experience, because the institution is a reference in the sonar field. IPqM also provided

In the Project’s term, ended in June 2015, CMRE scientists and engineers worked to design, develop and demonstrate at sea concepts of continuous, real-time passive underwater acoustic systems for maritime surveillance. The objectives have been successfully met by using innovative solutions integrated on board unmanned mobile platforms, i.e. both on an underwater glider (an autonomous underwater vehicle which uses shifts in mass to steer and changes in buoyancy to dive and surface)
