This is great. One could also envisage the provision of emergency
beacons that can report where they are, and can run for a long time
on very small batteries, since they may only need to transmit
a small burst every now and again. Essentially it just rings the
phone at an emergency services group and reports a problem and
where it is.

Does anyone know what accuracy the positional information will have?

My great goal is a personal navigation device / emergency beacon
for bushwalking/hiking/sailing etc.
