Pilot Navigation Systemdeveloped by Maritime University of Szczecin

IntroductionLimitations when navigate at constrained

water areas:•Weather conditions,•Visibility,•Night-time,•Dense traffic.

IntroductionPotential users of PNS:•pilots,• ferries,•other vessels permanently navigate at

definite area.

Manual data collection

DevelopmentPNS principles:•precisely determination of vessel’s

position at restricted area;•suitable type and content of information;•suitable form of presentation of that

information

DevelopmentTools 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 informationThe optimal set of information should

enable to make a planned manoeuvre:•safe;• in given time;• in given conditions.

Optimization of informationThe 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 > V1T2 > T1

Result: new safety contour displayed on the chart

Chart – prediction

Positioning subsystemThe 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).

SummaryThis 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
