About this manual

This manual is intended as a reference guide for installing, operating and maintaining

Simrad GC80 and GC85 Dual Gyro compasses.

The manual assumes that the operator is a qualified ship officer, or is under supervision

of a qualified person.

In this manual, references to buttons on the operator panels are written in boldface, but

in a different text style (e.g. SET button, DISP button, GYRO button).

Important text that requires special attention from the reader is emphasized as follows:

Note! Used to draw the reader’s attention to a comment or some

important information.

Caution! Used for warning the reader that a risk of damage to the

equipment exists if care is not exercised.

WARNING Used when it is necessary to warn personnel

that a risk of injury or death exists if care is

not exercised.

SYSTEM OVERVIEW

1SYSTEM OVERVIEW

This section provides an overview of GC80 and GC85 Dual

Gyro systems and their components.

Simrad GC80/GC85 Dual Gyro Compass

2 20221537 / D

1.1 Introduction

GC80 and GC85 Dual Gyro systems have been designated for

any size of vessels which requires more than one gyro system.

The system includes one common control unit, from which each

gyro system may be operated individually or as one dual system.

A GC80/85 gyro system enhances the navigation capabilities

and reliability. It eliminates the inconvenience and limitations of

magnetic compasses, and provides a variety of electrical outputs

to supply accurate and consistent heading information to other

navigational equipment.

-A GC80 Dual gyro system is designed for vessels with

speed up to 30 knots. The system complies with IMO

A.424 (11) and Wheel Mark Specifications.

-A GC85 Dual gyro system is suitable for high speed

vessels with speed up to 70 knots. It complies with IMO

A.821 (19) HSC.

GC80 standard and GC85 High Speed Dual gyro systems have

different sensitive elements, but use identical GC80 Dual control

unit. The systems are identified with divergent dip switch

settings in Master compass and in the control unit.

Note! A GC80 or GC85 system is identified by the labelling on top of

the Master compass’ case as shown on the figure below.

The labelling on the control unit is identical for both gyro

systems.
