1. Pilot Navigation System
developed by Maritime University of Szczecin
Stefan Jankowski

2. Introduction Limitations when navigate at constrained water areas:
Weather conditions,
Visibility,
Night-time,
Dense traffic.

3. Introduction Potential users of PNS: pilots, ferries,
other vessels permanently navigate at definite area.

4. Stationary PNS Collecting information subsystem
Data processing Subsystem
Visualization of navigation information Subsystem
Prediction subsystem – hydrodynamic model
Electronic chart (Data base)
DGPS
Gyro
Rudders
Bow thrusters
Propellers
Wind

5. Portable PNS Collecting information subsystem
Data processing Subsystem
Visualization of navigation information Subsystem
Prediction subsystem – extrapolation model
Electronic chart (Data base)
Compass DGPS
Manual data collection

6. Development PNS principles:
precisely determination of vessel’s position at restricted area;
suitable type and content of information;
suitable form of presentation of that information

7. Development Tools and methods : Optimization of information in PNS;
Visualization of optimal information;
Creation of very specific Electronic Chart;
Methods for adjusting vessels waterline;
Tools for assessment and verification of satellite positioning systems.

8. Optimization of information
The optimal set of information should enable to make a planned manoeuvre:
safe;
in given time;
in given conditions.

9. Optimization of information
The optimal set of information :
heading;
course over ground;
speed over ground;
distances to the berth;
safe depth contour;
rate of turn;
cross speed.

10. Visualization
Shore visualization

11. Visualization
Fairway visualization

12. Chart – adjustment

13. Chart – safety contour V2 > V1 T2 > T1
Result: new safety contour displayed on the chart

14. Chart – prediction

15. Positioning subsystem
The most favourable solutions:
stationary PNS - positioning subsystem made up of DGPS receiver and gyrocompass (p = 1.3 m);
portable PNS - positioning subsystem made up of compass GPS (p = 1.5 m).

16. Summary
This system is not a standardized electronic chart and has following distinctive features:
integration with the water area,
integration with the vessel,
optimal information,
optimal user’s interface,
predicting and supporting manoeuvring.

17. Summary
Portable version - pilots.

18. Summary
Stationary version – ferries

19. Summary – new features
