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.
