📡 Skydex Feeder Network

How to join

1. You need a running ADS-B receiver — a Raspberry Pi with an SDR stick and the free adsb.im image (or any readsb/ultrafeeder setup). Total hardware cost from ~€75.
2. Register a receiver above — you get a personal connector line.
3. Paste the line where your feeder keeps extra aggregators: on adsb.im that is Setup → Expert → “Add additional Ultrafeeder arguments” and the line must end with a semicolon; on plain ultrafeeder it is ULTRAFEEDER_CONFIG. Restart the feeder.
4. Done — your traffic appears on the network coverage map within a minute, and aircraft scans in the game over your area are served by your receiver.

Questions, or your feed isn't showing on the map? Ask in Discord — #feeders — a human answers.

The deal, in plain words

• Non-exclusive. Keep feeding FR24, FlightAware, adsb.lol and anyone else in parallel — multi-feeding is the community norm and we encourage it.
• Free, voluntary, revocable. Disconnect any time by removing the line; remove the receiver here to delete its registration.
• What you grant us: a non-exclusive right to use the data your receiver sends in Skydex products (the game, its public pages and API). ADS-B is an open, unencrypted broadcast; you are responsible for the legality of reception in your country (it is legal in the EU, US and most of the world).
• What we promise: we don't resell your raw feed — it powers the game, full stop. Your receiver's exact location is never published (coverage maps use rounded positions only).
• The long version: feeder privacy & data licence — what we store, what we publish, what we never publish, and how to leave.
• Perks: the 📡 Feeder badge appears on your Skydex profile automatically once your first packets arrive (live now). Uptime-based premium perks come next — we only started measuring uptime in August 2026, so the clock starts on the same day for every station, however long it has been feeding.

Questions feeders ask

Can I keep feeding other networks?

Yes. Skydex is one more output next to FlightAware, Flightradar24, adsb.lol and the rest, and your receiver sends the same data to all of them at once. Nothing about your other feeds changes.

What hardware do I need?

For aircraft: a Raspberry Pi or any Linux box, an RTL-SDR stick and a 1090 MHz antenna, from about €75 in total. For ships: a second stick and a 162 MHz antenna. A receiver that already runs readsb, dump1090, ultrafeeder or the adsb.im image needs nothing new.

How do I connect my receiver?

Sign in, press Add receiver and copy the line you get. On adsb.im it goes under Setup → Expert → "Add additional Ultrafeeder arguments", on ultrafeeder into ULTRAFEEDER_CONFIG. For ships, docker-shipfeeder takes your station ID as SKYDEX_FEEDER_KEY, and AIS-catcher takes one extra -H output.

I look after a receiver on someone else's network. How do I add it?

Sign in, press Add receiver on this page and tick the box for a receiver that already feeds under its own id. If your browser is not on the receiver's network, you get a one-time command instead: run it on the receiver over SSH, or on any device on its network, and the station joins your account with everything it has already fed. The command works once and expires after 15 minutes.

How big is the network?

93 aircraft receivers are registered. 314 of them are online right now. Together they heard 42,862 aircraft in the last 24 hours. The stations stand in 20 countries. 12 ships receivers deliver AIS.

Is my antenna's location published?

No. Station pages and network maps show a 25 km square, never the point where the antenna stands. The position is optional; without it a station gets no range figure and no reception rose.

What does my station get?

A public station page with uptime, range and a reception rose, a place on the station leaderboard, and Feathers for every day it is up at least 80% of the time: 20 a day for an aircraft receiver, 30 for a ships receiver. The aircraft and ships it hears appear in the game's live sky.

How many receivers can one account have?

Up to 20, aircraft and ships together. Each receiver is registered on its own and gets its own station page and ID.

Does Skydex do MLAT?

Yes, since October 2026. Add a second line next to the ADS-B one in your ultrafeeder config, with the same uuid: mlat,feed.skydex.online,31090,uuid=<your uuid>; Your station's Setup tab on this page shows the exact line and whether the station is in sync. MLAT needs four or more receivers that hear the same aircraft, so it computes positions where several stations stand close together; elsewhere the connection works and waits for neighbours.

Can I stop feeding?

Any time. Remove the line from your receiver, and remove the station on this page if you want its registration gone too.
