Your neighborhood terrorist drone maybe sooner than you think...

Here is a guy flying his drone with heads-up goggles and 2.4 Ghz wireless
camera giving him the flight view.  The RPV drone ground-station antenna
tracker operates by receiving a continuous stream of live GPS location
data as a part of the aircraft telemetry downlink (or APRS).  from this,
AZ/EL data is computed and the antennas pointed.

I built a GPS APRS driven antenna but we only used it once for a balloon
flight.  Now, I am thinking it would be nice to keep it on the air all the
time, scanning the sky for incoming S band video.  Who knows who is flying
what out there. My 4' s band dish would pick such a wireless camera up
several miles away.
