Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 8728 was prepared by Technical Committee
lSO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation.
This second edition cancels and replaces the first edition (IS0 8728:1987),
which has been technically revised.
Annex A forms an integral part of this International Standard. Annex B is for
information only.

1 Scope
This International Standard specifies the construction, performance and type testing for gyro-compasses required by
Chapter V of SOLAS, 1974.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards indicated below. Members of IEC and IS0 maintain
registers of currently valid International Standards.

3 Definitions
For the purposes of this International Standard, the following definitions apply.
3.1 gyro-compass: Complete equipment including all essential elements of the complete design.
3.2 true heading: Horizontal angle between the vertical plane passing through the true meridian and the vertical
plane passing through the ship’s fore-and-aft datum line; it is measured from true north (000”) clockwise through
360°.
When the gyro-compass equipment is not installed on board ship, 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 latitude.
3.3 settled: Stable situation when any three readings taken at intervals of 30 min are within a band of 0,7”, with
the compass level and stationary.
The settling time is the ela
