OpenSky Network Data
The OpenSky Network provides multiple ways to access its
rich air traffic datasets, ranging from real-time APIs to
historical archives and curated scientific datasets. Whether you're looking for structured SQL-based
queries,
programmatic API access, or preprocessed datasets for research, these tools offer powerful insights into
global
air traffic patterns. Explore the options below to find the best method for your needs.
Historical Database - Trino
Besides our public API, we provide free access to our full dataset through an SQL-like query
interface
using Trino and Minio. This service is available to university-affiliated researchers,
governmental
organizations, and aviation authorities for aviation-related research and incident
investigations.
Private or commercial entities must contact us for a license.
Access Trino
OpenSky API
Explore our REST API documentation and interact with real-time air traffic data. The OpenSky
API
provides structured access to live and historical aircraft position data, making it a
powerful tool
for aviation researchers and developers.

Data Tools
The OpenSky community provides various tools for accessing and processing air traffic data.
These
tools include Python, R, and MATLAB libraries for querying the Trino database, interacting
with the
API, and analyzing prepared datasets.
Available Data Tools:
Traffic - Python Air Traffic Data Processing
pyModeS + pyOpenSky
em-download-opensky + em-processing-opensky
R-based Wrappers (openSkies, osn, openskyr)
ADSbDataParser
Stone Soup
Other Wrappers (C#, Typescript, Perl, Go, Rust)

Aircraft Database
Besides tracking data, it is necessary for most research to have metadata about the tracked aircraft.
OpenSky's aircraft database aggregates official and unofficial sources in order to provide this metadata.
The database as a whole can be downloaded in .csv format. We have a number of monthly snapshots so the metadata
is preserved how it was in a particular month.
Currently, the database is only updated irregularly, we will bring it fully back in the future.

Database
Alerts
OpenSky provides real-time and historical aircraft alerts, allowing you to monitor
emergency squawks,
loss of signal events, and other notable flight anomalies. These alerts are generated
based on
and Mode S messages received from the network.
Use the alerts system to track specific events of interest, such as emergency
transponder codes (e.g.,
7700 for general emergencies), communication loss, and other significant occurrences in
global airspace.

COVID-19 Flight Dataset
The **COVID-19 Flight Dataset** captures the impact of the pandemic on global air traffic.
Derived from OpenSky's full dataset, it provides cleaned and enriched data on flights observed
by more than 5500 receivers since January 2019. The dataset was maintained until December 2022,
offering researchers a unique opportunity to analyze aviation trends during one of the most
disruptive periods in modern history.
