Unmanned Commercial Ships
Auto-docking system on commercial vessels and on recreational marine and fishing vessels in Japan is expected to start after 2020. Robotic commercial ships are being developed by Japan, Norway, China, UK and others shipping nations.
Auto-docking system uses RTK (Real Time Kinematic) GNSS (Global Positioning) technology, which gathers precise satellite positioning information from a known point to the vessel, to provide accurate real-time positioning. Corrective data from digital repeater systems to improve positioning precision even further to accurately guide ships into docks or for navigation.
