Once the signal is received by the LUT, it is processed for location and sent to a Mission Control Centre (MCC). The
MCC sorts the alert data according to geographic search and rescue regions and distributes the information to the
appropriate Rescue Co-ordination Centre (RCC), or if outside the national search and rescue area, to the
appropriate MCC that covers the area where the distress signal was detected. The RCC in turn takes the necessary
action to initiate search and rescue activities.
The International Cospas-Sarsat System will cease satellite processing of 121.5/243 MHz beacons from 1 February
2009. From that date only 406 MHz beacons will be detected by the Cospas-Sarsat satellite system. This affects all
maritime beacons (EPIRBs), all aviation beacons (ELTs) and all personal beacons (PLBs)
1.6.2 DISTRESS LOCATION DETERMINATION
See figure 7.1.b
The location of the distress signal is determined by taking measurements of the doppler shift of the EPIRB frequency
when the satellite first approach and then pass the EPIRB.
The actual frequency is heard at the time of closest approach (TCA). Knowing the position of the satellite and using
the received doppler signal information, it is possible to determine the location of the Tron 45S/SX from the satellite
at the TCA. At the LUT, actually two positions are calculated. One is the actual position (A) and the other is the
mirror image (B) position. A second satellite pass confirms the correct location (A). With the 406 system the real
solution can be determined on the first pass with a reliability of nearly 90% and down to an accuracy of less than 5
km (3.1 miles).
1.6.3 EPIRB REGISTRATION
Normally the MCC will contact the vessel or the contact person registered in a shipping register and/or an EPIRB
register (Ships owner, family member etc.) before alerting the RCC. This is to determine if the alarm from the EPIRB
for some reason is a false alarm, and an expensive rescue operation can be avoided. Because of this it is important
that the ships data is correct in the shipping register or in the EPIRB database.
Tron 45S/SX purchased in some countries will have a registration form attached to it, it is important that this
registration form is completed by the owner and returned to the place the EPIRB was purchased or to the address
specified on the registration form.
Other countries use the already available shipping register to obtain the necessary information for a vessel in
distress, in these countries the ship is already registered and no registration form is necessary, however it is vital that
the coding of the Tron 45S/SX is kept up to date with data on the ship (nationality, call sign, etc.), to minimize the
time from an alarm to the start of the search and rescue operation. Reprogramming the Tron 45S/SX can be done at
authorized JOTRON agents in more than 180 different places throughout the world.
If you are a resident of the United States, you must register this beacon with the National Oceanic and Atmospheric
Administration (NOAA) using the registration card included with the unit. Fill out the form and send it to:
SARSAT Beacon Registry, NOAA-SARSAT, E/SP3, FB4, Room 3320, 5200 Auth Road, Suitland, MD 20746-4304
Vessel owners shall advise NOAA in writing upon change of vessel or EPIRB ownership. Transfer of EPIRB to
another vessel, or any other change in registration information, NOAA will provide registrants with proof of
registration and change of registration postcards.
