SART stands for which of the following?

• A. Satellite Acknowledgment Radio Transponder
• B. Search and Rescue Transponder
• C. Satellite Academic Rescue Tool
• D. System for Automatic Rescue Telemetry

Answer: (B)

SART is a radar-based safety device that acts as a transponder to aid search and rescue. It stands for Search and Rescue Transponder, and its job is to respond to an interrogating radar with a distinctive signal. When a rescue radar sweeps over the SART, it triggers a response that appears on the radar display as a string of dots or a recognizable pattern, allowing the operator to determine the direction and approximate distance to the distress source. This makes it much easier to locate people or vessels in trouble, especially in poor visibility or rough seas. It is not satellite-based and does not involve telemetry or academic tools, which is why the other options don’t fit.
