When a person is in distress at sea, it’s critical that search and rescue (SAR) teams can find them quickly. One of the primary tools used to locate people in these emergencies is the 406 MHz distress beacon. These beacons send out a signal that enables rescuers to pinpoint a person's location. To improve the effectiveness of SAR missions, optimising how these signals are received and tracked by SAR units is essential. This process is called "distress homing," and it involves ensuring that rescue teams can accurately detect and locate the signals from these beacons.

406 MHz beacons are equipped with technology that allows rescue teams to receive the exact location of the person in distress, even before they arrive on the scene. SAR units that can detect both the 406 MHz signal and the AIS (Automatic Identification System) signal from certain types of beacons can pinpoint the distress signal faster and more accurately.

For the broader SAR community, optimising distress homing is critical. Rescue coordination centres (RCCs) and SAR teams need to ensure that their equipment is compatible with the various types of distress beacons in use today. Some modern beacons, like EPIRB-AIS and PLB-AIS devices, emit both 406 MHz location signals and AIS signals, which means SAR teams must be trained to distinguish between different types of signals and the technical nuances requirements of them. By ensuring that all teams can identify the correct signal and location, SAR operations can be more effective and better coordinated, improving rescue times.

The work being done to optimise how distress beacons are tracked is vital to the safety of those in distress. By upgrading equipment, improving coordination, and sharing best practices across the global SAR community, rescuers are better prepared to save lives when emergencies occur at sea.
