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. WebMay 23, 2024 · The satellite's orbit passes through the equator on the ground-track map (the ascending node) at point B with an inclination angle from the equator of i. We can calculate i as: We can see from this result that a direct orbit must have a launch azimuth between 0° and 180°. A retrograde orbit must have a launch angle between 180° and 360°. highgui100 dll
