🔍 Key Concepts

• GMDSS distress beacons (EPIRBs and SARTs) and what types of signals they transmit • The difference between satellite alerting signals (COSPAS-SARSAT 406 MHz) and local homing signals (e.g., 121.5 MHz or radar SART replies) • What equipment can and cannot receive homing signals (GPS receivers vs. SAR aircraft/ships’ direction-finding gear or radar)

💭 Think About

• Ask yourself: Which device or system actually uses a bearing to home in on a signal locally, and which system just gives a position via satellite? • Think about what the COSPAS-SARSAT satellites do: Do they track a homing beacon directly, or do they detect a different type of signal that leads rescuers to an area where they then use homing? • Consider whether a standard GPS receiver listens for any distress or homing frequencies, or if it only receives signals from GPS satellites.

✅ Before You Answer

• Verify which GMDSS devices produce local homing signals versus satellite distress alerts in the GMDSS syllabus or manual. • Confirm whether COSPAS-SARSAT is associated with detecting homing frequencies or only the 406 MHz distress alert from EPIRBs. • Check what type of equipment is described as giving bearing information to the signal’s source (e.g., DF equipment, radar with SART, etc.), and whether a GPS unit does that.
