COSPAS/SARSAT System

distress events using Doppler processing techniques and is less susceptible to ob-
structions which could block a signal in a given direction. The system is comprised
of instruments on board the satellites which detect the signals from the distress
beacons. Ground receiving stations, referred to as Local Users Terminals (LUTs)
receive and process the satellite downlink signal to generate the distress alerts.
The distress alerts, generated by the LUTs, are then received by Mission Control
Centres (MCCs) which then forward the alert to Rescue Co-ordination Centres
(RCCs), Search and Rescue Points of Contacts (SPOCs) and other MCCs.

INSTALLATION

The EPIRB1 should be mounted where it is easily accessible in
an emergency. The bracket should be securely fixed to a flat
bulkhead using the three screws provided. Mounting dimen-
sions are shown in the drawing. If the unit is to be mounted
externally it must be mounted in the optional manual release
housing to provide long term protection and to prevent the
EPIRB being accidentally knocked off in heavy weather.
Do not mount the EPIRB closer than 1 metre to any steering
compass as this may affect the accuracy of the compass.
Keep the EPIRB away from any strong magnetic sources such
as loudspeakers, compass compensation magnets, etc., which
might cause inadvertent activation.

The COSPAS/SARSAT system utilises two satellite ar-
rays to provide distress alert and location data to
search and rescue authorities. The GEOSAR
system can provide near immediate alerting
within the coverage of the receiving satel-
lite. The LEOSAR system provides coverage
of the polar region beyond the range of the
GEOSAR system. It can calculate the location of
