Sunsynchronous Orbit Design
This HP Prime program can be used to compute the mean orbital inclination for a sunsynchronous satellite in Earth orbit.
The software provides two different types of userdefined input; <1> user input of mean semimajor axis and eccentricity <2> user input of mean perigee and apogee altitudes A sunsynchronous orbit has a nodal regression rate that approximately matches the Earthâ€™s heliocentric orbital rate around the Sun. The orbit plane of a sunsynchronous maintains a fixed geometry with respect to the EarthSun line.
