Modified sentences and requirements for IEC 61162-1

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 61162-101 has been processed by IEC technical committee 80: Maritime navigation
and radiocommunication equipment and systems.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
80/363/PAS 80/376/RVD
Following publication of this PAS, the technical committee or subcommittee concerned will
investigate the possibility of transforming the PAS into an International Standard.

This PAS document relates to International Standards of the IEC 61162 series. The document

has been co-ordinated with the NMEA Standards Committee.

This PAS shall remain valid for an initial maximum period of 3 years starting from 2003-09.

The validity may be extended for a single 3-year period, following which it shall be revised to

become another type of normative document, or shall be withdrawn.

INTRODUCTION
This document is issued as a IEC Publicly Available Specification according to the IEC/PAS

approval process. This agreed process allows the latest information on modified sentences to

be placed in the public domain in a shorter timescale than revising the appropriate

international standards.
The publication of this PAS is intended to provide information on the interface standards

which have been upgraded, modified or introduced in the light of experience with earlier

editions of the IEC Standard 61162-1.

This publication IEC/PAS 61162-101 will be aligned with similar standards adopted by the
NMEA in the latest version 3.12 of NMEA 0183.
A second IEC/PAS 61162-100 is available which deals solely with the interface standards
required to implement the AIS. A future IEC/PAS 61162-102 will be made available
concerning the additional requirements for the Voyage Data recorder (VDR).
This PAS will be replaced at a future date by, or be included within, a revision of the
international standard IEC 61162-1.

Modified sentences and requirements for IEC 61162-1

1 Scope
This PAS document for IEC 61162-1 contains additional requirements for existing sentences

and details additions to the existing format which have been found desirable in the light of
field experience.
This is the second PAS document to be developed for the IEC 61162-1, reference should be
made to IEC/PAS 61162-100 which covers the requirements of the universal shipborne
Automatic Identification System (AIS).
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
Additions to this list are concerned solely with the new AIS and IEC/PAS 61162-100 should be
referred to for details.
3 Definitions
3.1
Parametric sentences
(Reference IEC 61162-1 Section 5 : Data format protocol)
These sentences start with the “$” delimiter, and represent the majority of approved
sentences defined by this standard. This sentence structure, with delimited and defined data
fields, is the preferred method for conveying information.
The basic rules for parametric sentence structures are:
a) The sentence begins with the “$” delimiter.
b) Only approved sentence formatters are allowed. Formatters used by special-purpose

encapsulation sentences cannot be reused. See Annex C, tables C.1 and C.2.
c) Only valid characters are allowed. See Annex B, tables B.1 and B.2.
d) Only approved field types are allowed. See Annex A, table A.1.
e) Data fields (parameters) are individually delimited, and their content is identified and often
described in detail by this standard.
f) Encapsulated non-delimited data fields are NOT ALLOWED.
3.2
Encapsulation sentences
(Reference IEC 61162-1 these are new sentences : see note below)
There follows a brief description of the Encapsulation sentence. Note that a full description is
to be found in the IEC/PAS 61162-100 for the universal shipborne Automatic Identification
System (AIS).
These sentences start with the “!” delimiter. The function of this special-purpose sentence

structure is to provide a means to convey information, when the specific data content is

unknown or greater information bandwidth is needed. This is similar to a modem that

transfers information without knowing how the information is to be decoded or interpreted.

The basic rules for encapsulation sentence structures are:

a) The sentence begins with the “!” delimiter.

b) Only approved sentence formatters are allowed. Formatters used by conventional

parametric sentences can not be reused.

c) Only valid characters are allowed.

d) Only approved field types are allowed)

e) Only Six bit coding may be used to create encapsulated data fields.
f) Encapsulated data
