How would that be accomplished? An improved inertia switch???

I think I see the sematics you were getting at there (false signal vs
unconfirmed situation), but for the record, the 406's are registered
into a database with contact information. So when an activation is
detected somebody can get on the phone and (try to) contact the
registered operator to determing if the aircraft is actually in
trouble.

Right. And the satellites are able to pinpoint the location of the
ELT signal an order of magnitude better than the 121.5 MHz ELTs. But
if there isn't some improvement in the triggering mechanism, I fail to
understand how there might be less false alarms; they will remain at
99% of the total ELT signals reported I would think.
