Show HN: Orbit – AR satellite tracker, watch 15k+ objects

https://nagylukas.github.io/orbit.html
18•lukas9•3h ago
Hey HN! I made Orbit, an iOS app that allows you to see the satellites, planets, and constellations above you in AR, on a 2D map, and on a 3D globe. The app includes more than 15,000 objects tracked by CelesTrack, together with their pass predictions, descriptions, and detailed orbital data. A searchable catalog of all objects is also available, as well as a built-in chatbot designed to answer any space-related questions you might have.

This is my first published iOS app, so any feedback is greatly appreciated! App Store: https://apps.apple.com/app/id6772174570

The no-account and on-device location approach feels exactly right for this kind of app; how often is the orbital data refreshed?

How do you calculate the next passes over a given position?
