Since its launch in 2013, the OpenSky Network has quickly evolved to a large-scale air traffic control data collection and sharing platform. With more than 5000 sensors registered across the globe and more than 50000 users, the OpenSky Network is greatly contributing towards the vision of a more efficient, secure, and reliable operation of the airspace by providing open accessibility of air traffic control data to the public.

Following the successful events in past years, we are proud to announce the 13th OpenSky Symposium. The two-day event will be hosted by the Linköping University on Campus Norrköping in November 2025. Since its 8th iteration, the Symposium is also supported by the Performance Review Commission (PRC) of EUROCONTROL. The PRC aims to establish an Open Performance Data platform available in cooperation with Opensky Network and its community and will support the Symposium and some of the most relevant submissions. We encourage all submissions to consider the PRC research challenges outlined at the 11th Symposium on Safety (airspace complexity, flight interactions/separation), Environment (estimation of fuel burn/emissions), and System/Network Performance (traffic flow interdependencies).

The event is targeted at anyone interested in data-based aviation research. The Symposium will serve as a forum to discuss new ideas, the network itself, and research activities around OpenSky. Participants are invited to actively contribute to the program by presenting their projects at the Symposium. In the past years, the symposium attracted a diverse and interesting audience from research, authorities, and industry.

We are aiming for an in-person event to foster creative exchanges and discussions. There will be many opportunities to get to know the community during the social activities around the Symposium program.

Pre symposium: All submitted abstracts will be peer-reviewed. Authors whose abstracts are accepted by the programme committee will be given both the opportunity to submit a full paper and present at the symposium. Please note, at least one of the authors of a full paper must be on-site for presentation.

Post symposium: The submitted full papers will be peer-reviewed. The authors receive feedback and are asked to implement it accordingly. As soon as a full paper is accepted for publication by the programme committee, it will be published in the Journal of Open Aviation Science (JOAS) . The publication of final papers in the JOAS shall comply with its open data and reproducibility guidelines.

Templates

Abstracts and full papers should be prepared with the JOAS template (zip).
