MT610G 7
HOW THE PLB WORKS
Your MT610G PLB is a self-contained 406 MHz digital radio transmitter that emits
an internationally-recognized distress signal on a frequency monitored by the
COSPAS-SARSAT satellite system. The MT610G contains a unique identity code
which can be cross-referenced to a database of registered 406 MHz beacons,
allowing the beacon’s owner to be immediately identied in the event of an
emergency. The PLB includes a high-performance, solid-state light and 121.5 MHz
VHF homing signal to assist in leading rescuers to your precise location.
The MT610G also features an integrated GPS Receiver which when activated, will
automatically acquire a position and relay the latitude and longitude of the PLB
along with the personal identier and emergency signal.
The section below explains how your PLB utilizes the COSPAS-SARSAT system to
identify your exact location in case of an emergency.
ABOUT THE COSPAS-SARSAT SYSTEM
[1]The COSPAS-SARSAT is an international, humanitarian search and rescue system
that uses satellites to detect and locate emergency beacons carried by ships,
aircraft or individuals. The system consists of a network of satellites, ground
stations, mission control centres, and rescue coordination centres.
When an emergency beacon is activated, the signal is received by a satellite
and relayed to the nearest available ground station. The ground station, called
a Local User Terminal, processes the signal and calculates the position from
which it originated. This position is transmitted to a mission control centre where
it is joined with identication data and other information on that beacon. The
mission control centre then transmits an alert message to the appropriate rescue
coordination centre based on the geographic location of the beacon. If the location
of the beacon is in another country’s area of responsibility, then the alert is
transmitted to that country’s mission control centre.
The COSPAS-SARSAT system provides a tremendous resource for protecting the
lives of aviators and mariners that was unthinkable prior to the space age. With
a 406 MHz beacon, a distress message can be sent to the appropriate authorities
from anywhere on earth, 24 hours a day, 365 days a year.
