Hi Olcoolone,
First of all the mechanics and then the politics and paper shufflers side of things.
Every 406
epirb has a unique 15 digit hex id code built in. This code is transmitted every 55 seconds when the
beacon is activated. The code is picked up by a geostationary satellites and relayed to rescue coordination centres in both the country responsible for the area where the
beacon was activated AND the country where the
beacon is registered. Depending on language and various other things communication of the personal information about the person who registered the
beacon may be passed on from country of registration to country of activation in 5 to 10 minutes. If the
epirb had a built in gps an instant 'fix' with an accuracy of about 25 km will also be known. As far as I can figure in
Australia after the RCC pin point the site of activation it is then up to the state authorities (Police) to home in on the scene. In NZ for instance the RCC task people to actually go to the site of activation and rescue if alive or hand over to Police if fatal.
Now the politics and paper shufflers side of registration.
Convention says that countries will ONLY register epirbs where the unique 15 digit hex code of the
epirb contains the embedded 3 digit code for the country where the
epirb is being registered. So an
epirb with an Australian country code can only be registered in
Australia.
BUT please note, any
epirb from anywhere in the world will be heard in
Australia if it is activated in
Australia.
I understand that as epirbs sold in America must be registered in America you can buy on ebay and find that the
epirb may be brand new but already registered to a few names taken at random from the local telephone book by the seller.
In some countries (i.e. NZ) you can ring the RCC and tell them you will be in the country for six months with an
epirb and here are my details and
epirb id number. The RCC will make a note of your contact details so they can instantly get them if you activate your
beacon whilst in the country.
I would advise people to purchase within their normal country of residence but that doesn't stop you using the
epirb anywhere in the world.
An
epirb with out gps will not be pinpointed immediately it is activated. The activation will be noted immediately but there will be two possible positions where the
beacon may be located (up to 5000 km apart). A second pass by another satellite is required to pin-point the activation site and this could - in the worst case be up to 4 1/2 hours later. A position (+/- 30 km) of activation will then be known.
By 2012 all gps satellites will have a sarsat
epirb beacon receiver on board.
Hope that helps some. Your information was correct but it does not stop the emergency notification getting through, the
epirb still does its job anywhere any time.
