Future high precision navigation system for inland waterways (NAVWAT)
The NAVWAT application project analyses and utilizes modern GNSS (Global Navigation Satellite System)
and augmentation infrastructure to provide accurate position information to the boatmaster. The gathered
precise position information should be related to the information contained in the onboard ENC
(Electronic Navigational Chart) in order to support safety-critical manoeuvres.
The inland waterway sector experienced a substantial modernization in the past years through the introduction
of River Information Services (RIS) in many European countries. The aim of RIS is to increase safety and
efficiency in river transport through the introduction of innovative information and communication services
to users on ships and on land.
Considering the evolution of RIS services over the next 10 to 15 years the main focus is on the reduction of
accidents on European rivers. Past experience has shown that the most dangerous sections on rivers are those
where the fairway is narrowed by riverside infrastructure, e.g. river locks, bridges, berths, and ports. The
aim for the future will be to provide the boatmaster with accurate and reliable navigation information to support
his decisions, in particular during periods with limited visibility.
Thus, NAVWAT aims at providing accurate distance information between the vessel hull and the surrounding
infrastructure. The information shall support the boatmaster in judging the actual navigation situation correctly
and hence reducing the risk of collisions with infrastructure commonly found on inland waterways, such as river
locks, bridges and berths. This information has to be provided to the ship crew in real-time in a suitable
(graphical) way maximising the benefit of such a system.
