2 Pathfinder Smart Heading System - Owner’s Handbook

1 Introduction

1.2 System components

Fluxgate compass

The fluxgate compass is the direction sensor for the Smart Heading

System. It provides the GyroPlus 2 unit with information about the boat’s

current heading.

GyroPlus 2 unit

The GyroPlus 2 unit contains:

• a rate gyro sensor that measures the boat’s yaw (its rate of turn)

• a micro-processor and related circuitry to combine this rate of turn

information with the fluxgate compass signal to provide fast, accurate

heading output

• inputs and outputs to allow connections with Raymarine equipment

Note: The GyroPlus 2 unit is primarily designed to be used as part of the

Smart Heading System. However, it can also be used as a ‘stand alone’

sensor to provide rate of turn information for Raymarine course

computers. Refer to the Appendix for more information.

1.3 Using the Smart Heading System

Powering-up

Excessive turn rates during the first 10 seconds after power-up may

temporarily reduce Smart Heading System performance. For optimum

performance, keep the boat as stable as possible immediately after

power-up. This will allow the GyroPlus 2 unit to stabilize.

Radar bearing alignment

For optimum MARPA and radar/chart overlay performance, the radar

bearing alignment must be correct on the Pathfinder Plus. Refer to the

Pathfinder Plus Owner’s Handbook for more details.
