Self‑contained demo with embedded Kepler elements parsed from TLEs. Accuracy is reasonable over hours; for precision, paste fresh TLEs below. Labels appear near points; only above‑horizon satellites are shown by default.

Notes
- North at top; azimuth increases clockwise (N→E→S→W). Radius encodes zenith distance (center = zenith, rim = horizon).
- Time slider shifts minutes from the chosen local time.
- Embedded orbits use a simple two‑body propagation (no SGP4 perturbations). For teaching & intuition.
