WebJan 26, 2024 · In an earth-centered inertial frame (ECI), a rocket sitting in the pad has a sizeable eastward velocity even before launch. In an earth-centered earth-fixed frame (ECEF), the rocket on the pad has zero velocity (as the rocket is then moving eastward as fast as the ground). This means different velocity vectors, which means different LVLH …
