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

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

  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
