    Excellent!  A few cautions, though, for those of us in the US:

    • Not all (or even most) aircraft are currently equipped with ADS-B transmitters ("out").  The FAA won't be mandating use of ADS-B out for most aircraft until 2020, and even then some aircraft (like gliders and powered aircraft without electrical systems) will not be included in the mandate.
    • ADS-B uses two separate frequencies (and protocols) in the US, 1090Mhz (1090ES) and 978Mhz (UAT), so two receivers would be required for detecting all ADS-B equipped aircraft.
    • If an ADS-B ground station is in the area, it will retransmit traffic data (including that derived from radar targets) on 1090ES and/or UAT, but only if it detects there is a aircraft equipped with ADS-B out capability in the area.

    This sort of thing is a great help for situational awareness, but it can not replace visual lookout as a result of these limitations...

    Great work John! This technology will really help us to fly FPV more safely and will also help for us to keep it a legal activity.
