Line-of-Sight & Polarization-Angle Demo

A from-scratch, interactive version of the geometry from my satellite-to-ground line-of-sight project. It places a satellite and a ground station in the Earth-fixed (ECEF) frame, draws the line of sight, and computes elevation, azimuth, range and ψ for the parallactic / polarization-angle geometry. ψ equals the polarization angle when the satellite's polarization is referenced to Earth's axis.

Try it: drag the globe to rotate it, and move the sliders. All inputs are generic examples, not project data.
