33. COSPOS -SARSAT SYSTEM
•IT USES THREE TYPES OF BEACONS :-
•ELT -EMERGENCY LOCATER BEACON (AIRBORNE)
•EPIRB (SHIP BORNE)
•PLB -PERSONAL LOCATER BEACON (HAND HELD)
•LOCATES DISTRESS BEACONS TRANSMITTING ON
121.5MHz AND 406MHz
•SIGNALS RECEIVED FROM THE BEACONS ARE
RETRANSMITTED ON 1544.5 MHz TO LUT (LOCAL USER
TERMINAL)
•DOPPLER SHIFT IS USED TO LOCATE THE BEACONS.
•SHIPS WHICH DO NOT CARRY L-BAND EPIRB SHOULD
CARRY EPIRBS OPERATING IN THE 406 MHZ RANGE.
