🔍 Key Concepts

• SART (Search and Rescue Transponder) purpose and basic operation • Difference between radar-based locating devices and satellite-based distress systems (like EPIRBs) • Typical range and limitations of SART equipment

💭 Think About

• Which type of equipment is a SART: is it primarily for satellites, radar, or visual signaling? • Think about which shipboard device appears as a series of dots or lines on another vessel’s radar screen during a search and rescue operation. • Consider the realistic range of small survival craft locating devices—are they intended for short‑range homing or very long‑range distress alerting?

✅ Before You Answer

• Verify which device uses 9 GHz (X‑band) radar to help rescuers home in on your position. • Confirm which equipment (SART vs EPIRB – Emergency Position Indicating Radio Beacon) is associated with satellite distress alerts and Rescue Coordination Centers. • Check typical operational range of a SART and whether it is designed for "greater than 1,000 miles" or for relatively short‑range homing.
