☢️ Orbit Radiation-Belt Dose Planner

Design a circular or elliptical satellite orbit and watch a live radiation-dose readout spike whenever its altitude crosses Earth's donut-shaped Van Allen belts — the inner proton belt or the outer electron belt — with trapped particles visibly gyrating inside each shell. Compare presets for a typical LEO orbit that stays below both belts, a GPS-like MEO orbit that cuts straight through both, and a GEO orbit that clears them entirely.
