Satellite trail simulation methodology flowchart. Left to right: 1) Orbital scene, based on the survey plan, Earth and Moon ephemeris, telescope (observer) and artificial satellite orbits. 2) Estimated sky position of the satellites along the simulated exposure. 3) Filtering satellite trails that cross the field of view, and are illuminated by the Sun, the Moon, or Earth. 4) Final record of satellite trail contamination on each exposure.
