Constellation Tuner

Constellation Tuner is an interactive, north-up 3D visualization and design tool for large satellite constellations. It lets you generate and fly Walker-style multi-shell networks (up to ~1,600 satellites), connect them with inter-satellite links (ISLs) that respect Earth occlusion, and watch packet traffic, ground-station uplinks, eclipse states, and co-channel interference in real time. Everything is rendered in a crisp 1-bit monochrome aesthetic with optional wireframe Earth, polar axis, orbit rings, and live spectrum/histogram analytics so you can immediately see coverage geometry, average degree, link SNR, and spectral efficiency.

Drag to orbit, scroll to zoom, and click any satellite to inspect it; the right-hand panel exposes every geometric, dynamical, connectivity, and frequency parameter as live sliders, plus preset templates (Starlink-dense, polar mesh, equatorial trunk, etc.), one-click route/flood/fault/repair actions, and saveable presets. Typical uses include rapid constellation architecture exploration, teaching orbital mechanics and mesh networking, stress-testing frequency-reuse plans, demonstrating resilient routing under node failures, and producing clean black-and-white presentation stills or hero shots of LEO/MEO designs.
