Working on a satellite tracker inspired by WillBuilds. Thanks will for posting your awesome globe. This one is base on a 13″ globe that spins instead to keep the wires from getting wrapped around the poles. Each axis turns at a constant rate (assuming a circular orbit). The setup can accommodate any circular orbit by setting the orbital inclination manually before placing the globe. The cart is held in place by to steel ball-bearings that will be aligned by two internal magnets on the orbital arm. Should be pretty neat.
