Chapter 1. Overview
•
GMDSS(Global Maritime Distress and Safety
System) is an internationally recognized distress
and radio communication safety system for ships
replacing the previous ship to ship safety system,
which relied on a manual Morse code system on
500 kHz and voice radiotelephony on Channel 16
and 2182 kHz. The GMDSS is an automated ship to
shore system using satellites and digital selective
calling technology.
The GMDSS is mandated for ships internationally by
the International Maritime Organization (IMO)
Safety of Life at Sea Convention (SOLAS), 1974, as
amended in 1988, and carries the force of an
international treaty.
•
SRG-3150 and SN-100 are composed of MF/HF
transceiver, DSC, DSC W/K Receiver, NBDP,
Automatic alarm telephone for suitable automatic
digital
communication
at
the
distress
and
safety/normal situation.
SN-100 uses being connected to Transceiver(SRG-
3150DN), output sub-carrier signal to transmit
NBDP data, displays the information on the display
which is demodulated RX signal receiving from
antennas.
•
SRG-3150DN frequency range :
TX : 1.6MHz~27.5MHz
RX : 500kHz~29.99999MHz
•
Type of Frequency/Power :
J3E : 150W(HIGH)/100W(MID)/50W(LOW),
F1B : 100W(HIGH&MID)/75W(LOW).
1.1. Features
(1) Possible Range
•
Because MF/HF Transceiver(SRG-3150DN), DSC
W/K Receiver, DSC, Distress alarm telephone is built
in SRG-3150DN, You are able to use itself without
NBDP terminal(SN-100). NBDP function is worked
by connecting SN-100 terminal, However it is not
available to use NBDP terminal only.
(2) Total Control System
•
SRG-3150DN is set up with the major modules
combined as one unit or circuits within a single
cabinet. Thus, it is possible to rationalize the total
control system by interlinking the respective module
controls.
•
And narrow band direct printing is available by
connecting NBDP unit(SN-100) to SRG-3150DN
simply.
(3) User Friendly
•
All general operation such as communication,
controls and monitoring, are performed by SRG-
3150DN, NBDP Terminal and printer which is
installed in a convenient place.
(4) Configuration
•
SRG-3150DN consists of one unit; therefore a
large space is not required for installation and
operation.
•
SN-100 Terminal is able to use by connecting with
SRG-3150DN cable.
(5) Trustworthy
Adopted new DDS (Direct Digital Synthesize) and
improved the quality of sound, trustworthy, stability.
(6) Construction
•
In order to endure in bad condition of marine
environment, hard aluminum body is manufactured.
(7) External Shape
•
Channel, Frequency, Transmitting and receiving
conditions can be seen on large LCD at one sight.
And each key is made by soft rubber material. It
has stylish shape and makes you feel comfortable
when you press the button, Further there is
frequency sheet for users. SN-100 NBDP Terminal
has large, thin, colorful LCD and convenient
keyboard.
