Methods for ensuring the navigation safety of unmanned surface vessel
Technology audit and production reserves, 2019 When creating unmanned surface vehicles (USV), special attention is paid to the safety of navigation. One of the main threats at sea is the threat of collision. Two main directions of ensuring the safety of navigation can be distinguished. The first is legal regulation and a number of international documents that are binding on all ship-owners.
