I don't think this is completely ADS-B; comparing KSTL on airportviewer[0] with FlightRadar24[1], FR24 doesn't have any ground tracks so I wonder if their data comes elsewhere.

- cpncrunch 9y agoHere is what they use: http://www.mosaicatm.com/commercial-solutions/viewer/ http://www.mosaicatm.com/commercial-solutions/viewer/ It basically just uses the transponder, so it will be mode-C or mode S (ADS-B). Right now most commercial planes have ADS-B, and 100% of them will have it after 2020. I think the main issue with FR24 is that you'll only pick up ADS-B signals within line of sight, so there may not be any receivers near KSTL. If you compare KSFO you'll see lots of ground activity on FR24: https://www.flightradar24.com/airport/sfo/map https://www.flightradar24.com/airport/sfo/map
