The 8th OpenSky Symposium

12/13 November 2020 at EUROCONTROL in Brussels, Belgium

Due to safety concerns and the uncertainty and restrictions caused by the still ongoing COVID-19 outbreak, we have decided that this year's symposium will be converted to an all-virtual event. The dates of the symposium remain the same. More details regarding the execution of the symposium will follow soon.

The abstract deadline has been extended until September 11, 2020!


Since its launch in 2013, the OpenSky Network has quickly evolved to a large-scale air traffic control data collection and sharing platform. With now more than 1100 sensors operated by volunteers across the globe and more than 15000 users, the OpenSky Network is today 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 workshops in the last years, we are proud to announce the eighth instance of the event. To acknowledge the increase in size of the event, we renamed the event from workshop to symposium from this year on. The two-day event will be hosted by EUROCONTROL in their headquarters in Brussels (Belgium) in November 2020. 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 the OpenSky Network. Participants are invited to actively contribute to the program by presenting their projects at the symposium. As in the last years, there will be many opportunities to get to know the community during the social activities around the symposium program. In the past years, the symposium attracted a diverse and interesting audience from research, authorities, and industry.

Call for Presentations & Papers

As every year, the symposium invites presentations from the community. The symposium is interested in presentations that can foster discussions and provide input for future development and research around OpenSky as well as a safer and more secure aviation in general. Potential presenters are free to choose any topic for their presentations, but the presentations should be related to the OpenSky Network in a wider sense.

This year as well, the authors of accepted presentations will summarize their work in form of short papers that will be made available as online proceedings. The submitted papers may partially overlap with other submissions to journals or conferences, but there should be an additional contribution that is original and has not been presented yet (e.g., new data analysis, description of a novel application, extension of existing work, etc.). The papers are welcome to depict images, graphs, and data that are part of the presentations. The paper submissions provide a means to incorporate reviewer feedback based on the abstract submissions, provide the opportunity for timestamping work in progress, and can be used as a reference. The program committee may make the short paper requirement optional in justified cases (e.g., cutting-edge industry talks) but all submissions with accompanying papers will be given preferential treatment in the selection process.

The OpenSky Symposium 2020 proceedings will be published in the MDPI Proceedings open-access journal.

Submission Guidelines

Authors can submit their contributions here:

The submissions consist of:

  1. Abstract submissions describing the idea of the work and presentation that will be given at the symposium. Abstracts should have a length of 1-2 pages and are due by September 4, 2020.
  2. Paper submissions describing and explaining the work in more details. Papers should be 6-9 pages long and are due by the start of the symposium on November 12, 2020.

Please ensure that your submissions are PDF files of a maximum of 2 pages (Abstract) and 9 pages (Papers), including references and appendices. Submissions should closely follow the instructions given for the MDPI Proceedings template here. We recommend using Overleaf which includes MDPI article template files. Abstract submissions may be anonymous (i.e., papers do not contain author names or affiliations), but author names and affiliations must be part of the paper submissions.

The EasyChair system will be used for collecting submissions, providing reviewer feedback, and notifications. Please visit for further information.
