Sensor data fusion in inland navigation

Safety of inland navigation has become for many years more and more important problem because there is tendency to move cargo from land and train transportation to inland shipping. To improve inland navigation River Information Services (RIS) have been established. In the European Union the implementation process of RIS is still in progress. For example first in Poland RIS for Lover Odra River will be completed to the end of this year. Problems of sensor data fusion in the process of inland navigation are described in the paper.
