But you need to understand a few limitations stagger.
The trackers acquire GPS, but only dump the tracks out over comms, when they manage to make contact. So if you watch the traces you see them disappear on descending scafell, and reappear on top of yewbarrow with a trace between. You have no idea where they were in the "blind period" until they come out of it. So they are not a complete answer to where you are, only where you were, subtle difference.
I was pointing wheeze to true satellite trackers (which use satellite phone links for comms as well as GPS) , (there are some cheap and nasty, not much good, but the next level up seem to be what is needed. They use satellites not GPRS or 3G so in principle do not have blind spots even in himalaya!. I did some math that implied it could be funded at less than a fiver a race per person, if I can get 20-30 races a year to sign up, and was potentially willing to invest in a 100 or so, to rent out to races - but provided a couple had been tried to confirm they are OK. Waiting for Wheeze to come back on that suggestion.
This is the sort of stuff that a safety officer of FRA should be trialling.
