README

SATDECK

SatDeck is a desktop-first 3D satellite tracking and visualization tool built with JavaScript and Three.js.

The project was originally aimed to become a fully-featured satellite tracking platform similar to
n2yo.com, satellitemap.space and other public trackers.

It loads Two-Line Element (TLE) data from a local .txt file and visualizes satellite orbits around Earth in real time.
Optionally, TLEs can be fetched from public sources such as CelesTrak, making it a live satellite tracking tool.
