Celestial Phenomena
Calculate position and velocity of bodies
Calculate the position and velocity of celestial bodies and implement Earth
nutation and Moon librations. Download ephemeris data for the celestial phenomena
blocks using the aeroDataPackage
function. To convert
these coordinates to Earth-centered Earth-fixed (ECEF), use the Direction Cosine Matrix ECI to ECEF block. Extract and return solar flux
and geomagnetic index.
