Beacon monitoring system
How the 406 MHz monitoring system works
- A distress beacon is activated.
- The signal is transmitted to the nearest sub-orbital satellite. These are satellites that remain in stationary position over the same area of the earth's surface or those that are constantly circling the earth in polar orbits.
- The signal is transmitted from the satellites to the nearest local user terminal. These are placed around the globe, to ensure signals are received almost immediately.
- The signal is passed to the Rescue Coordination Centre New Zealand (RCCNZ).
- RCCNZ mobilises search and rescue resources and directs them to the coordinates of the signal.
