Maritime Collision Regulations as a Structure for Space Travel [PDF]
, 2023 The exploration of space via manned and unmanned missions has been almost constant since the mid-20th century. With developing technology and the advent of private actors in space travel, the emerging problem of space traffic requires some form of ...

The Colregs and the Princess Alice [PDF]
TransNav, 2007 There is currently considerable interest in the international regulations for preventing collisions at sea (the Colregs). Suggestions for changes are made, but their validity is difficult to assess because, apart from some very limited simulator ...

Collision-Avoidance Decision System for Inland Ships Based on Velocity Obstacle Algorithms
Journal of Marine Science and Engineering, 2022 Due to the complex hydrology and narrow channels of inland rivers, ship collision accidents occur frequently. The traditional collision-avoidance algorithms are often aimed at sea areas, and not often at inland rivers. To solve the problem of inland-ship

Path Planning of an Unmanned Surface Vessel Based on the Improved A-Star and Dynamic Window Method
Journal of Marine Science and Engineering, 2023 In order to ensure the safe navigation of USVs (unmanned surface vessels) and real-time collision avoidance, this study conducts global and local path planning for USVs in a variable dynamic environment, while local path planning is proposed under the ...
