An interactive view of Earth orbit

Every tracked satellite is a SIGNAL//ZERO publication. Lock on to one and a ground station beams to it; click to open the research.

Under the hood

A dot-matrix Earth sampled from Natural Earth coastlines; thousands of objects on GPU-computed orbits (Walker LEO shells, MEO navigation planes, a geostationary belt that holds station over the ground, debris); line-of-sight beams from real deep-space and polar ground-station sites; bloom and an ordered-dither post-process; procedural Web Audio. Orbits are illustrative, not real ephemerides.

SIGNAL//ZERO is an independent research publication on aerospace cybersecurity, RF and software-defined radio, satellite communications, and offensive security. We take systems apart to explain how they fail — and publish the fix alongside the attack. Long-form, technical, and reproducible, one signal at a time.
