Interesting to see how much coverage can get spun up fairly quickly; ADSB.fi already tracking 42% the number of flights as ADSBx is.

Number of aircraft being tracked by the large flight trackers at 1600 UTC (10:00 AM CST).

#FlightRadar24: 14059
#RadarBox: 12536
#FlightAware: 12494
#ADSBExchange: 11008
#ADSBfi: 4618
#ADSBlol: 1905
#GrndcCtrl: 1561
#ADSBone: N/A

So it looks like enthusiast #ADSB network #ADSBExchange is going to be the basis of competition for #FlightAware, #FlightRadar24, #PlaneFinder and #RadarBox. But for a site that started to freely exchange #ADSB data, is that going to continue?

Almost all aircraft have a little box inside that outputs the location, callsign, speed, altitude, etc to anyone with an antenna in line-of-sight to that plane and a software radio dongle plugged into a #RaspberryPi.

I have a cheap antenna mounted on a pole that collects that data and feeds it to #adsbexchange, #Flightradar24, #radarbox, and #flightaware.

If you're ever on a flight from Melbourne, Sydney, or Brisbane to LAX you will be line of sight from my antenna about 10 minutes before landing, and I'm going to catch your plane's information.

Wave "hi" out the window! #adsb
