Sample Data

ADS-B Exchange not only delivers real-time data through our Enterprise API but also maintains an extensive archive of historical flight data. Since March 2020, we have captured
aircraft positions and all related ADS-B/MLAT/Mode S parameters worldwide at five-second intervals.

Our archival approach offers two distinct layers of information — a comprehensive overview of all aircraft in the airspace, and a more granular “one file per aircraft, per
day” format that enables in-depth trajectory and parameter analysis. This level of detail proves invaluable for historical flight-path studies, accident investigations, and Flight
Operations Quality Assurance (FOQA) analytics. Renowned investigative agencies worldwide have leveraged our data archives for their critical research.

This rich data repository serves a wide variety of applications and use cases. For those interested in sampling the data, we offer free access to the first-of-the-month data sets for
testing and evaluation.

Available Aircraft Data

Samples of the data ADS-B Exchange collects are available for evaluation. Complete data from the 1st of each month are made available free of charge.

For commercial agreements, all data can be pushed to customer-owned cloud storage (AWS/S3, Azure, etc.) on a daily or more frequent basis for import and analysis with your own tools.
Alternatively, you may pull data directly from our buckets.

Readsb History

Snapshots of all global airborne traffic, archived every 5 seconds starting May 2020 (prior data is available every 60 seconds starting July 2016).

Trace Files

Activity by individual ICAO hex for all aircraft during one 24-hour period, sub-organized by the last two digits of the hex code.

High Resolution Trace Files

Same as trace files, but with a higher sample rate of 2× per second — for detailed analysis of flight paths, accidents, and similar use cases.

Acas

TCAS/ACAS alerts detected by our ground stations, by day.

Operations

Using ADS-B path data, we determine takeoffs and landings (with runway used) at airports and heliports worldwide.

Supplementary Information

All files are in gzip-compressed format. The traces and hires-traces files are gzip-compressed but do not carry the .gz extension— your web browser may uncompress and display the raw JSON based on response headers, but any programmatic access should anticipate gzipped JSON.
