FAQs

Frequently Asked Questions

Space is hard. Some of these answers will hopefully make it a little easier.

Why Did You Make This?

When I was a Lieutenant in the Air Force, I was responsible for tracking satellites. I was frustrated with the 1970s technology I had to use, so I decided to build a better tool. I hope you find it useful!

Why is it free?

I'm a big believer in open source software. I think it's the best way to build software. I also think that space should be free and open to everyone. I hope that by making this app free, it will help people learn about space and satellites.

What do I do if I find a bug or have a feature request?

Please let me know! I am always looking for ways to improve the app. You can add an issue on GitHub or send me an email at [email protected].

Is this really accurate?

Yes! Keep Track relies on the Orbital Object Toolkit (also free) and that is tested against USSPACECOM's official algorithms. The results are within 1mm of the official results.

Is there a tutorial?

Yes! There is a full docs page that explains how to use the app. I am cotinuing to add to it, so if there is something you want to see, please let me know.

How can I access the app offline or on a mobile device?

You can download the app from the GitHub repository. It is already built and ready to go. Just download the zip file and extract it. There is a batch file that will start the app in chrome without any server required.

How often is the satellite database updated?

The TLEs are sourced from multiple websites and then the database is updated every 8 hours. Additional information about the satellites is sourced from twenty different websites and processed by the server daily.

How do I collaborate or integrate Keep Track with my own project?

If you want to collaborate, please reach out to me at this email. If you have a non-commerical project, I am happy to help and would love to hear about it. Some of the best features in the app were inspired by users.

Who Uses Keep Track?

Keep Track has been used in art, science, and defense across the globe. I am always looking for new collaborations, so please reach out if you are interested in incorporating my code into your project.

Cosmos Archeology

In November 2022 I had the privellage of participating in an exhibit at The École Polytechnique Fédérale de Lausanne (EPFL). The exhibit was called Cosmos Archeology and it was a collaboration between EPFL’s Laboratory for Experimental Museology (eM+) and Laboratory of Astrophysics (LASTRO). The goal was to provide a series of custom immersive interfaces specifically for astrophysical data, in the form of interactive data simulation and visualization, immersive projections, 3D film and augmented reality.

A Million-Year Picnic

In January 2024, my animated satellite visualizations were featured in "A Million-Year Picnic - Conversations on Mars," an innovative theatre experience at the Théâtre de Vidy in Lausanne, Switzerland, directed by filmmaker Pauline Julier.

Espace Ballon

Reopened in 2024, Espace Ballon invites you to discover the hot air balloon adventures from every angle. Learn about the 1st non-stop world tour of the Breitling Orbiter. From Icarus to Piccard, let yourself be carried away by the history of the lighter than the air.

The team there was kind enough to let me participate in thier "Altitudes" exhibit with a short film entitled, "Human Debris in Space 1957-2024" that explores some specific events over the last 60 years of space exploration and the altitudes at which they occurred.

Cosmos Archaeology (Shanghai)

Co-curated by Sarah Kenderdine, Jean-Paul Kneib, and Iris Long, the exhibition showcases collaborations between artists and prominent astronomical projects. It features works from various contributors, including my project "Dark Clouds of Debris" and other innovative pieces.

Originating from a 2022 EPFL project, Cosmos Archaeology aims to inspire the public about space science and foster dialogue on experimental museology and sustainable space. It highlights the latest space research advancements from Switzerland and China, exemplifying international scientific and artistic collaboration.
