Become a VHF Feeder

OpenSky Network is extremely proud and excited to announce that we are now starting to collect, store and distribute ATC voice recordings - just as we have done so far with ADS-B data.

If you are interested in becoming a feeder, please do check out this web page: https://atco.opensky-network.org/. There simple to follow instructions have been given on how to set up a receiver. In addition to the set-up web page, there are lots of useful blog posts on ATCO2 project web page: check those out too: https://www.atco2.org/news. The very basic, how-to-set-up-your-receiver post is here: https://www.atco2.org/news/setting-up-vhf-receiver-for-air-traffic-communication

One thing that we would like to stress is that we are still in the development phase and therefore there might be few issues here and there. If you encounter any of the issues, please do let us know by sending us an email to This email address is being protected from spambots. You need JavaScript enabled to view it. so that we can fix it.

There aren’t any feeder interfaces created yet, but we will change that  in the coming months.

Just to mention a few things: you will of course be able to access all data you provide to us. You will be able to access both the voice recordings and if the recording quality allows - the transcripts too.

We’ll also link the voice recordings with the aircraft trajectories - you’ll be able to follow the flight path and listen to the conversations between the ATC and the pilot.

We are really keen to understand what sort of services you are most interested in. So, all suggestions are most welcome. Just use the e-mail address given above.

Obviously better coverage means better service, so go on - get on board!

The same general terms apply for VHF data as for ADS-B (https://opensky-network.org/about/terms-of-use and https://opensky-network.org/about/privacy-policy).

All the hard work we’ve done has been under the European Commission funded project ATCO2. More about the project and its objectives and progress here https://www.atco2.org/

The 9th OpenSky Symposium: Programme & Registration

Registration is now open for the 9th OpenSky Symposium! We are having a hybrid event at Eurocontrol in Brussels this November with amazing scientific contributions from all corners of our vast community!

Programme is out and registration is open. See you in Brussels on November 18/19!

 

COVID-19 Dataset

Update: Data for October 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.
