The 9th OpenSky Symposium: November 18/19

The Call for Papers for the 9th OpenSky Symposium is out! We are planning to have a hybrid event at Eurocontrol in Brussels this November and welcome contributions from all corners of our vast community!

COVID-19 Dataset

Update: Data for June 2021 is out now!
During the pandemic, we have began to publish a much requested research dataset for all flights that we have tracked since 2019. You can find more information here and the dataset here.

Relatedly, you can check out the Bank of England using OpenSky data to nowcast economic indicators in the COVID-19 crisis.

OpenSky and ATCO2 Project

We are excited to and proud to be part of a project called “AuTomatic COllection and processing of voice data from Air-Traffic Communications” (ATCO2), a project funded by European Commission under Horizon2020 framework.

ATCO2 project aims at developing automatic ATC voice data transcription system. The outcome of the project can potentially be used to make aviation safer and more efficient in so many ways.

The good news is that you, too, can participate in the project! We are looking for people to annotate and check the quality of automatically transcribed voice data.

If interested, contact us be sending e-mail to This email address is being protected from spambots. You need JavaScript enabled to view it. for further details. More info can be found from our forum and project website www.atco2.org

Finished: Aircraft Localization Competition

We have teamed up with the AICrowd data science platform to bring aircraft localization research to the next level. Check out all information at AI Crowd: Aircraft Localization Competition and stay tuned for the code releases.

About the OpenSky Network

The OpenSky Network is a non-profit community-based receiver network which has been continuously collecting air traffic surveillance data since 2013. Unlike other networks, OpenSky keeps the complete unfiltered raw data and makes it accessible to academic and institutional researchers. With over 25 trillion ADS-B, Mode S, TCAS and FLARM messages collected from more than 3500 sensors around the world, the OpenSky Network exhibits the largest air traffic surveillance dataset of its kind. The mission of our non-profit association is to support open global air traffic research by universities and other not-for-profit institutions.
