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 40S MkII 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).
1.2.3 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 avo-
ided. Because of this it is important that the ships data is correct in the shipping
register or in the EPIRB database.
Tron 40S MkII purchased in some countries will have a registration form at-
tached 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 ne-
cessary information for a vessel in distress, in these countries the ship is alrea-
dy registered and no registration form is necessary, however it is vital that the
coding of the Tron 40S MkII 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 40S MkII can be done at authori-
zed Jotron AS 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 registra-
tion 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.
It is also possible to register online at: www.406registration.com to the Cospas-
Sarsat International 406MHz Beacon Registration Database (IBRD).
