GMDSS EPIRB and SART Operations 2

Question 1

On what frequency band does a radar Search and Rescue Transponder (SART) operate?

Accepted Answer

9 GHz (X-band)

Answer

A radar SART operates on the 9 GHz X-band frequency, responding to interrogations from standard marine radar sets carried by ships and search aircraft.

Question 2

How is a traditional radar SART typically activated?

Accepted Answer

Manually by survivors in the survival craft

Answer

Traditional radar SARTs are activated manually by survivors, who switch the unit on when they see or hear a searching vessel or aircraft approaching.

Question 3

What pattern does an activated SART display on a ship's X-band radar screen?

Accepted Answer

A series of 12 concentric arcs or rings

Answer

An activated SART generates 12 equally-spaced concentric arcs or rings on the interrogating radar screen, allowing rescuers to identify and home in on the distressed craft.

Question 4

What is the required minimum standby operating duration of a SART before it is activated by survivors?

Accepted Answer

96 hours

Answer

A SART must be capable of operating in standby mode for at least 96 hours before activation, ensuring it remains functional throughout an extended search and rescue operation.

Question 5

To maximize detection range, how should a SART be positioned when awaiting rescue?

Accepted Answer

As high as possible above sea level

Answer

Holding the SART as high as possible above sea level increases the radar line-of-sight distance, significantly extending the range at which a searching vessel's radar can detect it.
