These vessels can remain for long periods at sea, during which access to information must be avail- able to researchers whenever required, e.g., to commu- nicate with other members of a project, acquire updated and near-real-time data, etc. Therefore, a global commu- nications system is a capital expense for a research ves- sel. This article summarizes the communications system implemented in the Spanish RV García del Cid. The RV García del Cid is a multipurpose research ves- sel with a regional capacity that is part of the EuroFLEETS project aiming toward an alliance of European research fleets. It is managed by the Marine Technology Unit of the Spanish National Research Council (UTM-CSIC). The ship was built in 1979, and its characteristics are: a dead- weight of 183 t, a length of 37.2 m, a breadth of 8.4 m, a draught of 3.50 m and a capacity for 26 people (14 crew and 12 scientists or technicians). The vessel's objective is to support national and in- ternational scientific research of different disciplines in the Mediterranean Sea, the Iberian zone of the Atlantic Ocean and the Canary Islands. Hence, a global commu- nication system is needed. A very small aperture terminal (VSAT) communica- tions system was acquired to ensure the necessary cover- age. This type of system is often used to communicate via satellite and provide services such as internet access, te- lephony, fax and high-speed data communication. A new network management system, based on free software, was also implemented; it is a unified threat management (UTM) firewall that is an approach to information securi- ty whereby a single hardware installation provides all se- curity functions. This provides internet access to comput- ers filtering by MAC; quality of service to distribute the bandwidth by services or users; VPN service to access the equipment on the ship; DNS service to obtain the domain names of the network; and DHCP service to pro- vide the automatic configuration of network parameters.
