DockingAssist: A novel vessel navigation system design based on WiMAX and DGNSS

The DockingAssist system is a centralised, cost-effective, real-time navigation system that provides the necessary centimetre positioning and speed accuracy to ensure efficient and safe manoeuvring within a entire port area, thereby enhancing vessel trajectory and providing constant monitoring of moored/docked vessels. By reducing transit, this system will result in improved port traffic management and lower operating expenses, CO
₂
emissions and fuel usage, thereby lessening the environmental impact of shipping. The reduced transit time will increase throughput in ports with a low investment. Our solution is based on WiMAX technology transmitting DGNSS positioning data in harbours. We provide proof-of-concept results based on empirical measurements performed in a real harbour. We find that WiMAX fulfils the requirements for accurate vessel positioning and navigation in harbour environment while providing wireless network capacity also for other services.
