Skydex ADS-B network
Volunteers share what their antennas hear. Every aircraft they pick up flies in our live sky, lands in players' collections and gets a page of its own. Adding your receiver is free, takes a few minutes and doesn't stop you feeding anyone else.

Add your station in four steps
If you already run a receiver you need no new hardware, and your feeds to other networks stay exactly as they are.
Get a receiver
An RTL-SDR stick and a 1090 MHz antenna on a Raspberry Pi, any box already running readsb, dump1090 or ultrafeeder, or simply a Mac with our free app.
Get your station ID
Sign in on skydex.online/feed (free, with Google), press Connect a receiver and pick Aircraft (ADS-B). You get an ID and a ready-made line.
Add one line
Add it next to the aggregators you already feed. On adsb.im it goes under Setup → Expert → "Add additional Ultrafeeder arguments", ending with a semicolon. On ultrafeeder it goes into ULTRAFEEDER_CONFIG.
adsb,feed.skydex.online,30004,beast_reduce_plus_out,uuid=<your-station-id>;Check that it arrives
Press the button below from the same network as your receiver. Your station page goes live with the first messages.
Already feeding us through adsb.im or another aggregator list? The check finds that stream and lets you claim it, history included.
What your station gets
A public station page
Uptime, streak, range, a reception rose and every aircraft type your antenna hears.
A place on the leaderboard
Stations are ranked by Signal: uptime, reach and what you heard that nobody else did.
Feathers every day
20 Feathers for every day your receiver is up 80% of the time, plus 1 Tridents every 5 days. Spend them in the game.
Your sky in the game
Pilots flying over your city see the real aircraft you hear, and spotters catch them into their collections.
Every aircraft gets a page
Aircraft your network hears end up in an open directory of types, airlines and manufacturers.
Your location stays private
We publish your country and the nearest regional centre, never the position of your antenna.

Questions
How big is the network?
313 receivers are online right now, across 41 countries. Registered stations stand in 20 of them; the rest are reached by receivers that feed without a claimed station. Together they heard 42,821 different aircraft in the last 24 hours.
What is ADS-B?
A radio signal on 1090 MHz that most aircraft broadcast every second with their position, altitude, speed and identity. Anyone with a cheap receiver can hear it, and planes over a city are heard from 100 to 400 km away.
What hardware do I need?
An RTL-SDR USB stick and a 1090 MHz antenna on a Raspberry Pi or any Linux machine, or a Mac with our app. A spot by a window or on the roof helps more than an expensive stick.
Can I keep feeding FlightRadar24, ADS-B Exchange or adsb.lol?
Yes. Skydex is one more output next to them, not a replacement. Feeding several networks at once is normal and nothing here is exclusive.
Does it cost anything?
No. Feeding is free and so is the game. Your receiver earns 20 Feathers for every day it stays up.
Is my location published?
No. A station page names its country and the nearest regional centre, and maps draw it on a square about 11 by 7 km, never on the antenna itself.
How do I know it works?
Use the address check on this page from the same network as your receiver, or open skydex.online/feed: it shows each of your receivers as online, quiet or offline.
I already feed you through adsb.im. What now?
Your stream arrives with an ID nobody owns. Sign in, run the address check here from your home network and press Claim: the station becomes yours along with everything it has already heard.
How do I stop?
Remove the line from your decoder config. Your station page stays and shows the station as quiet.
Hearing ships instead?
AIS is a different band, 162 MHz, with its own antenna and decoder. The ships network has its own page.
