An ADS-B network with no single operator

Feed it alongside what you already run. Anyone can run a relay, and nobody can sell or switch off the data.

Live. Red is Tally MLAT.

How it differs

No single operator

Anyone can run a relay. Feeders fail over between them.

Signed at the antenna

Every batch carries your station key. No account.

Delivery is checked

Feeders verify relays hold their data.

MLAT on the relays

Solved per area, credited to the receivers used.

Take the raw back

Run a relay, get your area as BEAST via --beast-out.

Open data

CC0 in, ODbL out. Code MIT or Apache-2.0.

Feed Tally

Any box running readsb, adsb.im included.

curl -fsSL https://github.com/sky-commons/tally/releases/latest/download/install.sh | sudo bash

Reads BEAST on :30005. Opens no port, leaves other feeds alone.
Exact location for MLAT, or --precision <m> if rounded.
UAT: --uat 127.0.0.1:30978. Docker: ghcr.io/sky-commons/tally-feed.

Run a relay

One binary. --max-upload caps your bill.

tally-relay keygen > /etc/tally/relay.key
tally-relay --key /etc/tally/relay.key --max-upload 6Mbit/s \
  --listen 0.0.0.0:10900 --beast-out 127.0.0.1:30105
