Orbit ground track equation

WebMar 26, 2016 · This equation represents the speed that a satellite at a given radius must travel in order to orbit if the orbit is due to gravity. The speed can’t vary as long as the satellite has a constant orbital radius — that is, as long as it’s going around in circles.
