sattools-web

Satellite tracking tools for the web — a reimagining of the sattools toolkit by the Libre Space Foundation. From “what’s above me tonight” to publishing your own orbital elements, with a browser as the only requirement.

• Satellite catalog — browse the live TLE archive, search by name, catalog number, or Alpha-5 field, and inspect any element set.
• Pass predictions — when a satellite flies over your site, with visibility flags for optical observers.
• Sky map — the whole catalog over your horizon, with stars, trails, and a time machine.
• 3D orbits — Earth, orbits, footprints, and launch sites, live.
• TLE sets — your own working element sets: import, edit, set aside, and feed any tool here.

Goals

• Zero-install. The full sattools capability set, no local tooling.
• Fast answers. Passes over your site in three clicks, on live data.
• Own your elements. TLEs are your data — import, build, edit, set aside; never locked to one provider.
• Close the loop in the browser. Image → plate solve → measurement → IOD → orbit fit → published elements.
• Trustworthy numbers. Every computation verified against the original C implementation.
• Open and pluggable. AGPL, API-first, self-hostable, attributed.
