Early days
Marine radio was first installed on ships around the turn of the
20th century.
In those early days, radio (or "wireless" as it was known) was
used primarily for transmission and reception of passenger
telegrams.
Hilmi ECE GMDSS Instructor 2
INTRODUCTION TO G M D S S
-
Radio watchkeeping hours were not standardised, and there
was no regulatory requirement for carriage of radio by ships.
Indeed,
there was a general lack of regulation of the radio spectrum.
Amateur/experimental stations often interfered with commercial
stations and vice-versa.

All that changed one clear and cold April night in 1912...
The most modern passenger liner of the time, RMS Titanic,
sank on her maiden voyage after a collision with an iceberg.

INTRODUCTION TO G M D S S
Some 1500 people perished in the disaster. Fortunately, 700
odd people were saved, thanks mainly to the efforts of the
Titanic's two radio officers, who managed to summon help
from nearby vessels.

Hilmi ECE GMDSS Instructor 6
INTRODUCTION TO G M D S S
-
However, the vessel closest to the disaster (the Leyland liner
Californian) could not be summoned, as her Radio Officer had
just gone off watch after 12 hours on duty.
The Californian managed to establish communications with
other searching vessels after the Titanic had sunk.
But by then, it was too late - one thousand five hundred people,
including the cream of American and European society, had
frozen to death in the North Atlantic.
Hilmi ECE GMDSS Instructor 7
INTRODUCTION TO G M D S S
-
The Titanic disaster brought about a number of
fundamental changes to marine radio:
- carriage requirements and radio watchkeeping hours were
standardised;
- message priorities were standardised - i.e.: distress and
safety traffic always has priority;
- distress frequencies were standardised; and
- radio silence periods were introduced.

During the 1920's, 30's and 40's, marine radio advanced
with the technology of the day - radiotelephone operation
was introduced, and most importantly, High Frequency (HF)
came into widespread use, thereby allowing
communications over ever-increasing distances.

Of course, marine radio played a vital role in WW2 - the war
provided a great boost to radio technology in general.
Amongst other things, WW2 introduced direct bridge to
bridge communications, through the use of what was to
become the marine VHF radio band - known during the war
years as "talk between ships" (TBS).
After the war, Marine Radio incorporated the latest
achievements in electronics - solid state (i.e.: transistorised)
equipment and Marine Radar became commonplace.
Hilmi ECE GMDSS Instructor 11
INTRODUCTION TO G M D S S
-
However by the late 1970's, despite tremendous general
advances in communications, Morse Code still ruled the
marine radio waves.
After some 80 odd years of development, marine distress
alerting still relied on a human being sitting in front of a
receiver.
Ship's Radio Officers sent a distress message using Morse
Code (or radiotelephone) in the hope that another ship or
shore station would hear the call and respond.

Since the time of the Titanic, Marine Radio has helped to save
tens of thousands of lives, and become the key element in
Marine Search and Rescue (SAR).
Hilmi ECE GMDSS Instructor 14
INTRODUCTION TO G M D S S
-
Before the Global Maritime Distress and Safety System came
into force, marine radio equipment was required to provide
operation over a minimum specified range of 150 nautical
miles.
This was based on the (not unreasonable) assumptions that
ships usually travelled well-used routes and that there were
sufficient ships at sea and shore stations dispersed about the
world to receive distress calls.
Hilmi ECE GMDSS Instructor 15
INTRODUCTION TO G M D S S
-
However, if a ship was outside of the normal shipping
lanes or was rapidly overwhelmed by the forces of
nature, her distress alert may go unheard.... many
ships have gone to the bottom without any distress
signal being sent - they have "sunk without trace".....

INTRODUCTION TO G M D S S
The pre-GMDSS systems were, in reality, based on 1920's technology...
-
A new system
The International Maritime Organization (IMO) pondered the
shortcomings of the existing marine distress systems in the
mid to late 1970's.
The 1979 IMO Assembly decided that a new global distress
and safety system should be established in conjunction with
a coordinated SAR infrastructure to improve safety of life at
sea.
And so was born the Global Maritime Distress and Safety
System (GMDSS).
Hilmi ECE GMDSS Instructor 18
INTRODUCTION TO G M D S S
-
The GMDSS is designed to automate a ship's radio distress
alerting. It removes the requirement for manual (i.e.: human)
watchkeeping on marine radio distress channels.
The new system is quicker, more efficient and reliable than
the old manual Morse Code and radiotelephone alerting
systems.
The basic concept of the GMDSS is that Search and Rescue
(SAR) authorities ashore, as well as shipping in the
immediate vicinity of the ship or persons in distress will be
rapidly alerted so that they can assist in a coordinated SAR
operation with the minimum of delay.Hilmi ECE GMDSS Instructor 19
INTRODUCTION TO G M D S S
-
One of the principal advantages of the GMDSS is that the
system is actually an amalgam of various individual radio
systems, both terrestrial and satellite.
Distress alerts may be sent and received over short
and/or long distances, by ships of all sizes.
In other words, every ship is able to perform those
communication functions which are essential for the
safety of the ship itself and of other ships operating in the
same area - irrespective of the area through which it sails
and its size...

The Global Maritime Distress and Safety System
(GMDSS) is a system developed by the International
Maritime Organization (IMO), in conjunction with the
International Telecommunications Union (ITU).
Its primary purpose is to automate and improve
emergency maritime communications.
WHY GMDSS?
INTRODUCTION TO G M D S S
-
Hilmi ECE GMDSS Instructor 22
The basic concept of GMDSS is to enable shore
side search and rescue authorities in a distress
situation to rapidly alert shipping in the immediate
vicinity of the ship in distress and coordinate
search and rescue (SAR) operations between
shore side authorities and vessels assisting with a
minimum delay. GMDSS took several years to
develop and is continually being improved for the
safety of the mariner. With constant updates to the
system, it will prove to be a great new asset to the
maritime community.
INTRODUCTION TO G M D S S
WHY GMDSS?
-
Hilmi ECE GMDSS Instructor 2323
The 1974 SOLAS (Safety of Life At Sea) convention
required a radiotelegraphy watch on 500 kHz and a
radiotelephone watch on 2182 kHz and 156.8 MHz
(channel 16) on all ships of 1600 gross tons and
greater. Although the system has proven itself
reliable, its short-range ship-to-ship capability, manual
distress alerting, and aural watch keeping procedures
have limited its effectiveness in maritime safety.
INTRODUCTION TO G M D S S
Pre-GMDSS
-
Hilmi ECE GMDSS Instructor 2424
Technological growth has provided advanced
terrestrial radio systems and satellite communications
that have been integrated into GMDSS. This provides
a truly standardized global maritime communications
system with accuracy and reliability far exceeding the
concepts of the 1974 SOLAS Convention.
INTRODUCTION TO G M D S S
Pre-GMDSS
-
Hilmi ECE GMDSS Instructor 2525
GMDSS was developed to allow shore based SAR
authorities to effectively coordinate and manage a
rescue far at sea. This is accomplished by mandating
that vessels carry specified GMDSS equipment while
sailing in predetermined ocean areas.
The 1988 change to the 1974 SOLAS convention for
radio communications resulted in these GMDSS
requirements.
INTRODUCTION TO G M D S S
Development of GMDSS
-
Hilmi ECE GMDSS Instructor 2626
With improvements to this new communication
system, we have created a ship to shore and shore to
ship distress communications path in addition to the
ship-to-ship system.
Digital and satellite communication combined will
immensely improve the safety of the mariner.

The requirement of watch keeping on 2182 kHz and
156.8 MHz (channel 16 VHF) is changing.
As of 1 February 1999, watch keeping on 2182 kHz is
no longer required.
On 1 February 2005, watch keeping on 156.8 MHz
(channel 16 VHF) will no longer be required.
This has placed all watch keeping on a digital format
with Digital Selective Calling and Satellite equipment.

Under GMDSS, it is the responsibility of every
vessel to be able to perform all of these
communications functions regardless of the
ocean area in which it operates. These functions
are essential for the safety of the ship itself and
of other ships operating in the same area. If the
vessel is not able to conform to all functional
requirements, the vessel is not allowed to sail
until all requirements are meet.

Four geographic areas have been established based
on the capability of certain GMDSS equipment to be
carried in each area.
The major difference between the GMDSS and its predecessor systems is that the radio communications equipment to be fitted to a GMDSS ship is determined by the ship's area of operation, rather than by its size.
Because the various radio systems used in the GMDSS have different limitations, with regards to range and services provided, GMDSS divides the world's oceans into 4 areas (zones):
