Open data
Free daily ADS-B aircraft exports — one file per UTC day, hosted free on GitHub Releases. Open to all: no account, no token, no rate limit.
✓ Live. Daily files are downloadable now — open to all, no account needed. Today's file is a partial-day preview; the complete day's file replaces it after the UTC day finalizes.
What you get
Each monthly release holds one zstd-compressed Parquet file per UTC day (aircraft_diffs_YYYY-MM-DD.parquet) of ADS-B aircraft state diffs. Per-file row counts and SHA-256 checksums are listed in the release notes.
- Append-only diffs:
is_snapshot=truerows are full state; otherwise only changed fields are populated (forward-fill perhexordered bytsto reconstruct). - Columns:
ts, hex, flight, lat, lon, alt_baro, gs, track, squawk, type, plus the full readsb field set.
