Help keep this independent satellite visualization project running and improving.
Sat Tracker has ongoing cloud infrastructure and data-processing costs. If you find it useful, consider supporting the project. A portion of support received also goes toward public data providers, such as CelesTrak, that help make Sat Tracker possible.
Support is completely optional. Sat Tracker remains free to use. We believe in giving back to the public space-data ecosystem that makes this project possible.
⭐ $25+ Supporter Pin
Support Sat Tracker with $25 or more and choose one meaningful location to appear as a gold star on the globe and map after review. Example gold stars are shown until community supporter pins are approved. Please do not use a precise home address unless you are comfortable making that location public.
💡 Sponsor a Feature
