WebApr 1, 2024 · Here we consider satellites in circular orbits around the center of mass of the Earth–Moon system using the rotating coordinate system introduced in Section 2. If … WebAs the Earth is moving and rotating, we need a reference frame that is attached to the Earth itself. This is mostly imposed by the common characteristics of flight missions, which are expressed in terms of ground features (eg surface waypoints and landing sites). A common right-handed coordinate system is the Earth-Centered, Earth-Fixed frame ...
