Nothing prevents a mobile station or mobile earth station in distress from
using any means at its disposal to attract attention, make known its
position and obtain help. Nothing prevents a coast or land earth station
from using any means at its disposal to assist a mobile station in distress.
COSPAS-SARSAT
Low-earth, near-polar, sun-synchronous and geostationary orbiting
satellites search the earth for active 406 MHz emergency beacons from
aviation, maritime and terrestrial carriers in distress.
Satellite downlink signals are converted at the LUT and fed to the MCC
where the operator validates beacon information, matches position,
resolves ambiguity and alerts the relevant aeronautical or maritime rescue
coordination centre so that a rescue may be launched.
Digital Selective Calling
Sea Area A3 & A4
This technique uses digital codes to enable a radio station to establish
contact with and to transfer information to another station. Cape Town
Radio guards 4207.5 6312 8414.5 12577 and 16804.5 kHz. Subsequent
radiotelephone distress and safety traffic succeeding the original DSC
alert is conducted on simplex on: 4125 6215 8291 12290 or 16420 kHz
