Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 8, Ships and marine technology, Subcommittee
SC 6, Navigation and ship operations.
This second edition cancels and replaces the first edition (ISO 16328:2001), of which has been technically
revised.
Annex A forms a normative part of this International Standard. Annexes B and C are for information

speed craft
1 Scope
This International Standard specifies the construction, performance, and type testing for gyro-compass
for high-speed craft required by chapter X, SOLAS 1974 (as amended).
NOTE All requirements that are extracted from the recommendations of IMO Resolutions [Resolution
A.821(19) on performance standards for gyro-compasses for high-speed craft and A.694(17)] are printed in
italics.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
gyro-compass
complete equipment including all essential elements of the complete design, including both the gyro-
compass as heading sensor and the associated heading transmission system
3.2
true heading
horizontal angle between the vertical plane passing through the true meridian and the vertical plane passing
through the craft’s fore and aft datum line
Note 1 to entry: It is measured from true north (000°) clockwise through 360°.
Note 2 to entry: When the gyro-compass equipment is tested on the test stand, this “true heading” is regarded as
the true heading of the lubber line. Where a gyro-compass has the facility of introducing a correction by moving
the lubber line, the correction is set for the local lat
