A SART is used to locate a vessel or aircraft in distress once they are within range, while an EPIRB is used to transmit a distress signal over long distances. Difference between SART and EPIRB 📌 SART SEARCH AND RESCUE TRANSPONDER It is a vital equipment during distress for it helps in locating the position of the vessel in case it goes off-track. They are the most supportive equipments in case of an unprecedented emergency. It operates on the 9GHz frequency band (9.2 to 9.5 GHz) and generates a series of blips on the radar it is interrogated by EPIRB stands for Emergency Position Indicating Radio Beacon. This is a battery powered radio transmitter designed to release and float free from a sinking ship and to send an automatic distress signal. Over 500,000 EPIRBs have been installed world-wide, operating in the 406MHz frequency band. These EPIRBs relay their messages to ground stations worldwide. Newer EPIRBs also include encoded Global Navigation Satellite System (GNSS) position data and an Automatic Identification System Search and Rescue Transmitter (AIS-SART) locating signal. EPIRB distress alerts from U.S. coded beacons, as well as any EPIRB alert located in a U.S. SAR Region, are routed directly to a U.S. Coast Guard Rescue .
