I was excited to read about Garmin's GDL-90 Universal Access Transceiver
(UAT) for ADS-B traffic and FIS-B (free) uplink weather.  I find it
affordable for the amount of lifesaving data available through it.

However, I was not so impressed that I had to hook it up to an MX-20 in
order to display anything. (Too expensive.)

Has anyone done any work (or would like to) regarding getting traffic
and weather data out of the GDL-90 and into something like an iPaq or
PC?

I know I can buy a Mode S transponder that will receive TIS, but it will
neither be able to transmit ADS-B position reports, nor will not be able
to receive FIS-B weather updates.  The GDL-90 UAT is a much better
overall solution, if someone could get the data out into some standard
format.

I was part of a conversation yesterday, where an FCC vendor
thought CAT-62 was not network centric. Stupid technical
choice and all. Europe is gonna have a better ATC system
than the US in the next couple years!

Anyhow, here is one document that talks about the mix ADS-B
TIS-B conflict alerts, and everything. Using CAT-62, the TIS-B
message is built.

here is a similar document:

And then the ICAO study, starts at:

Talking about VDL mode 4 and UAT's

Digging in on google the details can be found out about.
