What
is SART carriage requirement?/How many SART used in ship?
300 GRT to 500 GRT – one
SART
Above 500 GRT – 2 SART
What is SART?
Search and Rescue Radar Transponder
What is the
purpose of SART?
To locate the position of survivors
during search and rescue
What is the
frequency of SART?
9 GHZ
( 9.2 GHZ – 9.5 GHZ)
What is
standby mode?
Ready for transmission
What is the
‘working hours’ of SART in
standby mode?
96 Hrs
What is the
‘working hours’ of SART
in activation?
8Hrs
What is the
shelf life?
5 years
What type of
battery is used?
Lithium
What is the
power out put?
400mW
Is the SART a
transmitter or a receiver?
It is a transponder
Transmitter and receiver, receiving
radar signals and transmits its signals
How does SART
transpond to the navigational radar?
When SART is interrogated by RADAR
signals, SART is activated.
(first signal – a rapid of 0.4
microseconds sweep
The first signal is followed by-
A 7.5 microseconds sweep
And-
This will be repeated 12 times.
This will cause – a series of 12
blips/arcs/circles on RADAR.
When the SART
is 5 mls away from radar, what is the indication in radar?
12 dots
When the SART
is 1 ml away from radar, what is the indication in radar?
12 arcs
When the SART
is within 1 ml from radar, what is the indication in radar?
12 concentric circles
What is
distance covered by SART for activation?
8 NM to a ship
40 NM to a helicopter at the height of
3000 ft – AIRBORNE DETECTION
What is the
indication in SART when it is activated?
LED will give a flash each 4 seconds
Buzzer will sound each time the SART
is hit by the Radar signals
What are the
supporting materials available with SART?
Telescopic pole and 10 meter rope
(lanyard) to secure SART
What is AIS
SART?
If you see 12
blips in your radar and saw a life raft 8 nm distance
Away from
your vessel, what initial action will you take?
Set VHF watch on CH16 and CH06 to
contact survival craft
Send DSC Distress Relay alert to all
stations/geographical area on 2187.5 KHz
SART TEST
Testing with X band Radar. (3 cm
radar. Typical navigational radar.)
Before carrying out SART TEST, check
whether any nearby ships are there.
If there are nearby ships, contact
them on CH 16 and inform them about the SART TEST.
Now set 12 NM range in the X band
radar
Take the SART to the bridge wing and hold
the SART at the clear view of the radar scanner (radar aerial). There should
not be any obstacles in between the SART and radar scanner
Now in SART, push and hold the switch to the test position
The person handling radar can see 12
concentric circles in the radar. Adjust the VRM pointer and bring it to the
outermost ring of the circles. Display will show 7.2 NM
The person holding the SART, can see a
visual light and can hear an audible tone.
How is SART
activated?
(In distress situation we use the
SART)
Break the seal, pull out the locking
pin
Switch automatically goes to ON
position (switch is spring loaded)
Now SART is on STANDBY mode.
That means it is ready for
transmission
When SART is interrogated by RADAR
signal, SART is activated
Maintenance
of SART?
Read the Instruction label (how to use
and how to test)
Check the battery expiry date and
annual service date
Check the lanyard
