Sun-synchronous Orbit Design - cdeaglejr - 09-10-2022 05:48 PM This HP Prime program can be used to compute the mean orbital inclination for a sun-synchronous satellite in Earth orbit. The software provides two different types of user-defined input; <1> user input of mean semimajor axis and eccentricity <2> user input of mean perigee and apogee altitudes A sun-synchronous orbit has a nodal regression rate that approximately matches the Earth’s heliocentric orbital rate around the Sun. The orbit plane of a sun-synchronous maintains a fixed geometry with respect to the Earth-Sun line. |
