1. Integrated navigation systems for inland navigation – beyond chart and radar Dr.-Ing. Martin Sandler in – innovative navigation GmbH Leibnizstr. 11 70806 Kornwestheim, Germany

2. Integrated navigation systems for inland navigation – beyond chart and radar Course (1) Actual situation (at river Rhine) (2) Usage of AIS (3) Machine control (4) Track control (5) Close range navigation (6) Integration with land based services (7) Conclusion

3. Actual situation Bridge layout Inland-ECDIS chart at central position in wheelhouse

4. State of the art Units: Two radars Inland ECDIS Inland AIS Autopilot (rate of turn control) Rate of turn indicator Rudder operation Machine controls Control of bow thruster Cameras ”Office” - Computer with internet access

5. Actual situation Interconnections:

6. State of the art Inland – ECDIS Navigation mode Integration of chart and radar head up orientation type approval required usage of depth information

7. State of the art Motivation for further developments: Enhancement of efficiency of transport by inland vessels: Minimizing fuel consumption Optimize usage of existing waterways Enhancement of safety of waterborne transport Usage of computers at various systems allows enhanced data exchange => “deeper” integration

8. Usage of AIS Inland - AIS will be mandatory: -Enhanced awareness of traffic situation New functions: - automatic prediction of encounters - lock management

9. Machine Control Enhance efficency of transport by inland vessel Optimizing speed of travel Depth of waterway speed of current CAN bus motor control can be interfaced to navigation system

10. Machine Control Optimization of speed for upstream passage, river Rhine: Influences: different water depth, different current velocity Rel. speed const Abs. speed const optimal speed Image by University of Stuttgart, Institute for System Dynamics (ISYS ) Absolute speed ≈ 5 km/h Fuel consumption reduction 6 %

11. Functionality Guidance of vessel along a curved line: - Suitable for curved (natural) rivers - mathematical model for dynamics and drift of vessel Basic track stored in navigation system (guiding line) Adaption of track according to traffic situation Adaption of track according to depth requirement and water level => Actual guiding line (transition line) used for navigation Track control

12. Functionality Display of guiding line in Inland- ECDIS chart => Integration of track control and Inland ECDIS Image by University of Stuttgart, Institute for System Dynamics (ISYS) Guiding line Transition line

13. Track control Benefits Enhancement of safety due to reduction of human error, situation unawareness Enhancement of efficiency due to less rudder activity. Enhancement of efficency by precise guidance along an optimized track

14. Background Task: Entering a lock chamber, docking Only some centimeters free space Supported by cameras and visual inspection (Wahrschau) danger of damages – to own vessel – to waterway infrastructure (locks) Close range navigation

15. Sensors Sensors used in robotics / automotive applications suitable for cm level navigation laser scanner ultrasonic distance measurements Image by University of Stuttgart, ISYS, Istitute for System Dynamics Close range navigation

16. Integration with land based services Current status Key technologies: Inland – AIS: Low capacity, specific tasks ETA / RTA messages for lock operation traffic lights Internet access by mobile communication infrastructure electronic reporting notices to skipper

17. Integration with land based services Future applications download of actual water level model IRIS II, currently in test download of chart updates

18. Conclusion Future system setup

19. Conclusion Future system setup Different types of displays: Navigation: radar + AIS + chart + close range sensors Chart overview with AIS, planning Conning, track control status Displayed screens may be assigned to monitors according to users needs / preferences cf. actual bridge of seagoing vessels
