The network's had a map for a while. As of this week it has a room too — a Dataero Discord for everyone feeding the network, watching the radar, or thinking about a node of their own. Pull up a chair: discord.gg/EuAwChgg #ADSB #avgeek #aircraft #flight #tracking

1/ A receiver came online overnight in O'Fallon, Missouri. Which is to say: the first node across the Atlantic. 2/ Until this morning the grid was Geneva, Edinburgh, Bologna. Today it includes St. Charles County, Missouri. Nobody asked permission. Somebody just pointed an antenna at the sky and decided we'd be part of what they fed. 3/ To our first American feeder: welcome. Whoever you are out there in Missouri — you just gave the rest of us a view of the Midwest sky. If you're in North America with a receiver running, you can layer Dataero on top of what you already feed. radar.dataero.eu/?utm_source=x&… #ADSB #planespotting #usa #missouri

1/ There's a kind of person who hears a jet and looks up. Most people trained that out of themselves by about age nine. Spotters never did. 2/ Easy to file them under harmless eccentricity. It's the opposite. An ADSB network is just a map of where people chose to point a receiver at the sky — and that's the same people who look up when they hear the engine. 3/ Take the enthusiasts away and you've got a website with a map and no aircraft on it. So: thank you. If you feed, layer Dataero on top of what you run. If you'd rather watch — the radar's open. radar.dataero.eu/?utm_source=x&… #ADSB #planespotting

From Tantallon Castle, looking east across the North Sea — Norway, Sweden, Denmark, Finland. None of them on our radar yet. A whole quarter of the map empty. If you're up there with a Pi and a balcony — say hello. radar.dataero.eu/?utm_source=x&… #adsb #scotland #norway #flighttracking #aviation

1/ Edinburgh for the weekend. Calton Hill on a Saturday afternoon, westerly off the Firth at 12, a jet climbing out of EGPH. 🧵 2/ Pulled up the radar on the hill. The departure was crisp on the trace. It got there because somebody in Scotland — a feeder I'll never meet — put an antenna in the right place and let it run. 3/ The receivers feeding our radar aren't ours. They sit on rooftops Dataero will never see. We point a network at what they catch. Scotland is the edge of useful coverage for the rest of the European map. 4/ Every antenna up here does work no antenna further south can. Trans-Atlantic departures. Highland traffic. The North Sea rotation. 5/ If you're in Glasgow, Aberdeen, Inverness, Dundee — clear view, Pi gathering dust — your rooftop would be a real piece of the map. radar.dataero.eu/?utm_source=x&… #ADSB #DataeroADSB

1/ Landed at Grimbergen this afternoon. VFR, westerly at eight. Pulled up the radar on the apron. 🧵 2/ The 738 I'd watched climb out of Zaventem twenty minutes earlier was crisp on the trace. My own descent into Grimbergen — four minutes of turning final at 1,500 feet — wasn't there. 3/ Not a network failure. Physics. ADSB at altitude is loud. A 737 at FL370 radiates over half a continent. ADSB at 1,500 feet over a small Belgian field is quiet, and a receiver thirty kilometres away in a Brussels apartment will not hear it. 4/ So the honest topology: we cover the high stuff well. The small stuff needs feeders close. A Cessna circuit at Spa. An SR22 scraping the trees at Kortrijk. Those want antennas near the field, not on the next city's rooftops. 5/ If you live within a few miles of a small European airfield and you've got a clear horizon — your antenna would do work no other antenna can. radar.dataero.eu/?utm_source=x&… #ADSB #generalaviation

1/ A message at 23:47 last night. From a feeder I've never met, to a feeder I've never met. About which connector was wrong. 🧵 2/ Not a Dataero support ticket. A reply on a forum thread. SMA, not N-type. The antenna wasn't going to see anything until that got sorted. Two replies later it was sorted. 3/ The receivers feeding our radar aren't ours. They sit on rooftops Dataero will never own, run by people we'll never meet. That's the topology. We point a network at what they catch. 4/ You cannot procure the midnight reply. You cannot SLA your way into a stranger walking a stranger through a connector at half-eleven on a Tuesday. It happens because the people running the receivers care. 5/ If you already feed somewhere, layering Dataero on top is five minutes. The part that matters takes years. radar.dataero.eu/?utm_source=x&… #ADSB #DataeroADSB

Every aviation hobbyist can name the moment they started looking up — a balcony, a thumb, a contrail, a low pass. Someone was usually there pointing. The hobby passes through people. Run a node, hand it down. radar.dataero.eu/?utm_source=x&… #adsb #avgeek #aviation #flight #aircraft

France: continent's busiest airspace, almost zero ADS-B feeders. Italy lit up at the weekend, Switzerland the day before. So — France? Lyon with a balcony, Toulouse with a roof, an Auvergne village with a horizon — Dataero takes the feed. radar.dataero.eu/?utm_source=x&… #adsb #avgeek #aviation #airport #flight #tracking

Italian Tuesday on Dataero. (Wednesday, technically.) The first Italian feeder went live in Venice this afternoon. Marco Polo is in. The Adriatic is in. The Dolomites are in. The map has not looked this good in a while. radar.dataero.eu/?utm_source=x&… #italia #adsb #aviation #avgeek

Dataero just picked up its first feeder in Scotland — a single rooftop in Edinburgh, a stretch of airspace newly visible to the network. Lovely. Cheers, - Sandy radar.dataero.eu/?utm_source=x&… #avgeek #edinburgh #scotland #egph #adsb #flighttracking #aviation

3am, Brussels. Calm and foggy. Couldn't sleep, opened the radar — two freighters east over the North Sea, a red-eye climbing out of Lisbon, the first transatlantic forming up south of Iceland. The continent quieter at this hour but never empty. radar.dataero.eu/?utm_source=x&… #adsb #avgeek #aviation

If you already run an ADS-B receiver in Europe — Dataero adds, it doesn't replace. Same Beast or MLAT feed, an additional destination, community-owned. ✈️ radar.dataero.eu/?utm_source=x&… #adsb

Saturday at Kraków-Balice. A320 rolling out. You feel it before you hear it. The guy next to me at the fence checked his phone after — his Dataero node at home had picked up the same aircraft we'd just watched climb out. Half the people there are running nodes, I think. radar.dataero.eu radar.dataero.eu/?utm_source=x&… #ADSB #planespotting #DataeroADSB

The shape of European airspace as the people who live under it can see it. Receivers in Bologna, Tallinn, Porto, Kraków — community rooftops, contributing what they hear to a continental view. Coverage isn't a feature. Coverage is what happens when enough people are paying attention. radar.dataero.eu/?utm_source=x&… #ADSB #planespotting #DataeroADSB

ADSB: every aircraft broadcasting position, altitude, heading, ID — continuously, on 1090 MHz, in the clear. Unencrypted. Unprotected. Anyone with a receiver can decode it. If your antenna can hear them, you can see them. radar.dataero.eu/?utm_source=x&… #ADSB #planespotting #DataeroADSB

Two hours of green hexadecimal scrolling past on the terminal. Then one line resolves. A blip on the map — among hundreds the network is already tracking. Your blip. The first aircraft your antenna ever decoded. The ten-thousandth feels routine. The first one doesn't. radar.dataero.eu/?utm_source=x&… #ADSB #planespotting #DataeroADSB

Late afternoon in Bologna. The light slants across terracotta tiles and a slim antenna picks up the airliners climbing out of Marconi. Someone soldered the connector. Someone ran the coax. Someone decided their balcony was the right place for it. radar.dataero.eu/?utm_source=x&… #ADSB #planespotting #DataeroADSB

1/ A balcony in Helsinki, just past sunset. A thin antenna catches a 787 climbing out of Vantaa toward the Baltic sea. ✈️ 2/ It isn't magic. A Raspberry Pi, an SDR dongle, a piece of coaxial cable, and someone who decided to build the catching themselves. 3/ Thousands of setups like this quietly turn rooftops and balconies into receiving infrastructure for a community-built airspace map. 4/ The feed goes to a network that belongs to the people feeding it. Not to a company selling subscriptions back to the operators. 5/ Watch the airspace at radar.dataero.eu — or layer Dataero on top of an existing receiver. radar.dataero.eu/?utm_source=x&… #ADSB #planespotting #DataeroADSB
