On-Star*

^^^^^^^^^^^^

This system might be usefull in countries where, unlike in the U.S.,
you can reliably get coverage more than 5 miles outside a major city.

Or in countries where, unlike the US, major cities are rarely more than ten
miles apart.

If you have actually had that sort of trouble in the US, perhaps you are
using the wrong system.

Does anybody know how much On-Star costs and would
they consider taking on
aviation customers? It's got to beat ELT.

What I don't get is why someone doesn't just make
an ELT that speaks the GPS coordinates (and
tail #, etc. entered by the user) over the 121.5
frequency.

No decoding, no satellites, just an ELT that
also has a voice and tells it over the 121.5 freq
every few minutes. Mate a $100 GPS to a
$200 ELT to a text-to-voice device. Doesn't
this seem much simpler?

And talk about easy to find the false transmissions!
Heck, you got the coordinates AND the tail number?
Shouldn't be hard to find THAT guy at the airport
bar...

A clever pilot could adapt his ELT to this, as long as it was one with
voice input. Buy a pocket pc that has text to speech capability, install
a GPS card in it, connect the headphone output to the ELT's microphone
input and you have the basic system. When you crashed, the ELT would
start transmitting it's signal, and the "voice" from the pc.

OK, there'd be some details:

- you'd want to parse the data stream from the GPS, so only your ID and
the coordinates were spoken
- probably want to have the pc key the microphone and transmit voice
only once a minute
- you'd need power to the PC during normal flight, and maybe a larger
battery for it so it'd last as long as the ELT battery if it lost power
from the glider in the crash
- it would need to be mounted and connected carefully so it would be
likely to work after a crash

It might be easier and cheaper to buy one of personal locators that has
a GPS in it, and figure out how to make a crash activate it.
