Besides, isn't that what happens when you press the EPIRB button? Doesn't the US get the signal and take if from there?
No, it gets automatically routed to the country that is responsible for the waters the emergency is in.
It does not get routed to the country of origin of the MMSI number attached to the EPIRB.
In Asia Australian boats have that problem too, particularly those that rely on HF radio. Thinking that its monitored. It is.... By the USA and Australia... But not by anyone else!
The cost of diverting aircraft is high.... For a country like Brazil can afford it, but a third world country?
When we used a Sattelite phone in an emergency it was wonderful to be instantly connected to someone who spoke the language, in a duty room, fully versed with these type situations. (It was to the UK navy when we were in the Gulf of Aden). So I kinda think the best thing is to have a sat phone and the phone number of ones own country's rescue service. Faster than EPIRB too.... Did you note the satelite takes an hour to resolve the lat and Lon?
At 1425 Byers swam to retrieve the EPIRB ..... The EPIRB signal was received at 1505 hrs by the Geostationary Operational Environmental Satellite (GOES)-12. The position of the sinking, 27°28′S 40°53′WCoordinates: 27°28′S 40°53′W, was resolved at 1525 local time. .
The phone is much quicker. You describe he situation, and have your own nationals liaising with the rescuing country.
Of course you still set off your own EPIRB so you rate of drift is calculated etc.
