A real-time 3D presentation of Earth and its artificial satellite shell.
Orbit Veil renders more than 18,000 active satellites and tracked debris objects around a day/night Earth. The interface provides constellation and debris layers, satellite/NORAD search, orbital paths, live propagation, pause/resume controls, and time travel from -240x to +240x.
- CelesTrak two-line element (TLE) sets provide orbital elements.
satellite.jsruns SGP4 propagation locally in the browser.- A Web Worker keeps propagation work away from the presentation thread.
- Earth textures and TLE snapshots ship with the static site, so Orbit Veil needs no backend, account, or API key.
- Once the orbital elements are loaded, positions update continuously without polling an API every frame.
No build step is required. Serve the repository root with any static server:
python -m http.server 4173Then open http://localhost:4173.
Opening index.html directly with a file:// URL is not supported because browsers restrict workers and asset requests outside an HTTP origin.

This repository intentionally contains only the standalone Orbit Veil experience. The Digital Sea portfolio shell, its navigation, music, and unrelated projects remain in the main nuroctane.xyz repository.
TLEs change over time. Replace the snapshot files in data/ on a roughly two-hour cadence when publishing fresh orbital data. Keep each TLE record's fixed-width formatting intact.
