Abstract: The objective of this project was to design and build an autonomous underwater platform that could reach a depth of 20m. It would be programmed with a trajectory, including horizontal and vertical motion, initially positioned using GPS. Inertial navigation would be used for part

ABSTRACT Time synchronization and localization are key requirements for distributed underwater systems consisting of numerous low-cost submersibles. In these systems, submersibles are highly resource constrained and typically have limited acoustic communication capability. We investigate

Abstract — This paper is devoted to local sensing and com-munication for collective underwater systems used in net-worked and swarm modes. It is demonstrated that a specific combination of modal and sub-modal communication, used simultaneously for robot-robot and robot-object detection, can create

In this article we describe a novel method for the detection of explosives and other hazardous substances in the marine environment using neutron activation. Unlike the other considered methods based on this technique we propose to use guides for neutron and gamma quanta which speeds up and simplifies identification. Moreover, it may provide a determination of the density distribution of a dangerous substance. First preliminary results of Monte Carlo simulations dedicated for design of a device exploiting this method are also presented.

Abstract. This paper shows the result obtained during the operative test of an anti-intrusion undersea magnetic system based on a magnetometers' new self-informed network. The experiment takes place in a geomagnetic space characterized by medium-high environmental noise with a relevant human
