Satellite Orbit and Ground Track Demo

Sub-satellite latitude βs and longitude λs. Default preset matches the tutorial problem (i = 65°, T ≈ 6 h, MEO).

How to use: Press Tutorial preset to load the parameters from the tutorial problem (i = 65°, T ≈ 6 h, MEO). The left panel shows the orbital plane in inertial space (the orange dot is the ascending node, ♈ marks the vernal equinox direction). The right panel traces the ground track in real time on the Earth-fixed map. Try varying the inclination to see the maximum latitude change, or the period to see how the longitudinal shift between orbits responds.

Notation: βs, λs = sub-satellite latitude & longitude; βg, λg = ground-station coordinates (not used here).
