THE SART

THE SEARCH AND RESCUE RADAR TRANSPONDER :-

The word "SART" stands for 'SEARCH AND RESCUE RADAR TRANSPONDER' also  named as SURVIVAL CRAFT RADAR TRANSPONDER. The carriage requirements of SART , on board  cargo and merchant ships is governed by the , CHAPTER III - REGULATION - 6 , of SOLAS CONVENTION.

"At least one Radar transponder shall be carried on each side of  every passanger ship and every cargo ship of 500 GRT or above . At least one radar transponder shall be carried on cargo ships of 300 GRT and above but less than 500 GRT."

Once triggered up , the SART starts transmitting on a frequency of 9.2 to 9.5 GHz  and these frequencies are picked up by any aircraft or water craft fitted with X- Band radar and , are displayed as 12 dots (.) in a straight line if that craft is within 8 to 10 miles range from  the SART. As these craft's proceed in to the direction of the 'dots' (SART)  and gets close to the position of the SART, say about 2 to 3 nautical miles , these 12 dots , turn in to the semi circles and when further close to SART , say 1 nautical mile , the dots turn in to the concentric circles which denote the exact position of the SART  or the position of the vessel in Distress.
