SART is the main means for locating vessels or persons in Distress , it can be located as a permanent fitting or operated as a float free device.
A SART operates on 9 GHZ / X band ( 96 Hours in standby and 8 hours in transpond mode )
SART will not respond to 3 GHZ ( 10 cm or S band radar )
SART is a small buoyant battery powered omni directional radio receiver and transmitter..
The Lithium batteries used allow operation for min 96 hrs in the stand by condition followed by a min 8 hours of transmission.
On receiving a signal from any Ship / Aircraft (X Band ) radar , it transmits a series of response (homing ) signals , these signals appear as a line of 12 evenly spaced blips on the radar screen extending 8 NM outwards along its line of bearing. the blip closest to own vessel indicates the position of SART site. on approaching the SART , the blips becomes wide area arcs at about 1 NM and concentric circles when in the SART Position.
A SART mounted 1 MTR (Minimum Height ) above sea level can be detected at 5 miles by a radar with 15 meter scanner height. ASART should also respond when interrogated by a X- band radar fitted to an aircraft operating at a height of 3000 FT at ranges up to 40 Miles.
When a SART is switched on , it will show light to indicate that it is working.
When SART will be interrogated by ship or Aircraft Radar , there will be a visual ans audible sound indicating to the distressed survivors that a radar has activated their SART.

Monthly Checks of SART :-
- Checks the physical condition , (for damage )
- Check the Battery expiry date
- Check the condition of the lanyard
- check the condition of the mounting pole
- check that the seal is intact security latch
