  • Ratio between messages with barometric and GNSS height.

    Hello,

    Does anyone know the ratio between emitted ADS-B position messages from aircrafts containing barometric vs. GNSS heights?

    Just a few statistics from my receiver near Frankfurt, germany after running ModesDeco2 26 days uninterruptedly:
    Airborn position reports with pressure height: 50.270.000 (quite the same with velocity reports)
    Airborn position report with GPS HAE: 3.839
    targeting 76ppm of the messages providing a GPS height.
