🛰 Gravity Probe B: Geodetic Effect and Frame Dragging of a Gyroscope in Orbit - 3D Physics Simulation

Fly a gyroscope satellite around a rotating Earth and watch general relativity tilt its axis: the 6.6 arcsecond-per-year geodetic drift and the 41 milliarcsecond-per-year frame-dragging drift. Post-Newtonian equations, orbit averages and published checks.
