🧪 Advanced Satellite Internet Simulation

Interactive simulation of a low-Earth-orbit broadband constellation pass: a phased-array ground terminal electronically steers its beam to track the highest satellite and hands over to the next one as it drops below the elevation mask.

This simulation models the mechanic that actually keeps a low-Earth-orbit broadband terminal connected: as a satellite orbits overhead its elevation angle rises then falls, and a phased-array ground antenna electronically steers its beam to track whichever satellite is currently highest. When the serving satellite's elevation drops below a configurable elevation mask, the terminal hands over to the next satellite in the plane — exactly the make-before-break handover logic used by real megaconstellations. Real orbital mechanics (Kepler's third law) sets the satellites' true angular speed for a given altitude, while a playback-speed control compresses the ~95-minute real pass into something watchable, and live readouts track elevation, beam-steer angle off zenith, orbital period, and a running handover count.

⚙ Under the hood

This simulation investigates the technical aspects of satellite internet technology. It demonstrates how signals are transmitted between satellites and ground stations, considering factors like signal propagation and latency.
