Is my data arriving?

Feeder perk
The API with Pro’s limits and features, free
Since your receiver sends us its data, your Free API keys can get the Pro plan limits and features at no cost: 300 requests a minute, 10 million a month, the whole world, plus overflights, emergencies, tracks of the last 90 days and the runway in use. For non-commercial use. Turn them on from this same network.

What flew past you
Lightcone shows the aircraft that passed near you and your receiver did not receive, and how you compare with nearby receivers. Then your range by direction and altitude, the terrain and a check-up of your setup. Only you can see the page. The map also needs MLAT enabled.

Before assuming something is broken: this page checks the address your browser comes from. If you are on a phone over mobile data, in another building, or behind a VPN, that address differs from your receiver’s and the answer will be negative even with a perfectly healthy feed.
Run this on the machine that sends the data: it leaves from the same address as the feed, so the answer is really about your receiver.
curl https://api.flyitalyadsb.com/api/am_i_feedingIf it is negative from there too

Check the destination:
dati.flyitalyadsb.comport4905for BEAST,30100for MLAT. -
Confirm the connection is actually open:
ss -tnp | grep 4905 -
On ultrafeeder, check the container logs:
docker logs -f ultrafeeder - A connection opened just now can take up to a minute to show up here.
What this means
BEAST
The stream of ADS-B messages your receiver decodes and sends us. This is the one that matters: if it is active, your data is going into the network.
MLAT
Multilateration, which derives the position of aircraft that don’t broadcast one by comparing arrival times across receivers. It is optional: you can feed BEAST without doing MLAT. How it works →
Not a feeder yet?
A Raspberry Pi, an RTL-SDR dongle and an antenna are all it takes. Feeders get the API with Pro’s limits and features, free, and Lightcone, their receiver’s own page. The guide covers everything, from hardware to configuration.
