Do you know if it runs on the SARSAT / PLB system, dose it use satellite message system with GPS, or a cellular biased?
If it uses SARSAT. If NOAA picked it up they would call AFRCC. Once it gets triangulated they would call the state and local emergence response to tell them where it's at and to see what kind of help they need.
In 2000 there was a PLB set off in our county. They were able to triangulate to about 5 sq miles and there were only 3 tracking units in all the county to pin point the location. I took 5 hours to find and get the person out of the woods.
The satellite message system will have a dead spots. If it's able to find 3 satellites it will send the location with the message. Most of them have under 5 messages they can send. How ever received the message would pass the information to the state and would be passed down to the local level.
There are so many places that a cellular system would not work. Depending on the system you need more than 1 tower to get a good location.
Depending on what resources are available would depend on what help you got.
There are still a lot of places that are all volunteer and most likely you'll end up with basic EMT's and then call for a chopper if needed once they find you.
I was an EMT from 1999 to 2004. Our call area was 55 to 90 minutes to the level 1 trauma center. The closer hospital was 30 to 70 minutes, but took no trauma at all. From the time the tones went off, got out of bed, pee, dressed, drove to the fire house, and get the first unit out the door could be 5 to 10 minutes. From the time the tones went off till you got to the hospital you could be looking at 2 hours...
Our dispatch would call to see if there was a chopper able to fly and put them on stand by depending on the call. When we saw what we were dealing with and asked for it you would still take 20 minutes to get to us. In our 60 sq mile run area there were only 6 places we could get a chopper to land and once you got there you would have set up a landing spot.
