Most satellite tracking tools tell you when a pass happens. OrbitGuard tells you how good it will be. A geometrically perfect pass during a geomagnetic storm is operationally useless. OrbitGuard scores each pass 0–100 by combining elevation, duration, Kp index, solar flux, and ionospheric TEC. One actionable number instead of cross-referencing five separate sources. Built using the same data sources professionals rely on — Skyfield, NOAA SWPC, and Space-Track.org.
