Pilot Navigation Systemdeveloped by Maritime University of Szczecin

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 > V1T2 > 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
