Pilot Navigation System
developed by
Maritime University of Szczecin
Stefan Jankowski
Introduction
Limitations when navigate at constrained water areas:
• Weather conditions,
• Visibility,
• Night-time,
• Dense traffic.
Introduction
Potential users of PNS:
• pilots,
• ferries,
• other vessels permanently navigate at definite
area.

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
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.
Optimization of information
The optimal set of information should enable to
make a planned manoeuvre:
• safe;
• in given time;
• in given conditions.
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.
Visualization
Shore visualization
Visualization
Fairway visualization
Chart – adjustment
Chart – safety contour
V2 > V1
T2 > T1
Result:
new safety contour displayed
on the chart
Chart – prediction
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).
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.
Summary
Portable version - pilots.
Summary
Stationary version – ferries
