Path: Interplanetary/Ephemeris
% The position vectors, gravitational parameters and velocity for the planets. The frame is centered on the Earth-Moon Barycenter and the plane is ecliptic, i.e. xy-plane is the mean earth's orbital plane. d cannot be empty on initialize. Type PlanetPositionEMBarycenter for a demo -------------------------------------------------------------------------- Form: [rB,vB,mu] = PlanetPositionEMBarycenter( action, d ) -------------------------------------------------------------------------- ------ Inputs ------ action (1,:) 'initialize' or 'update' d (1,n) Julian date (days) for 'update' or planet ids (1-9) for initialize ------- Outputs ------- rB (3,n) Planetary position vectors vB (3,n) Velocity vectors mu (1,n) Corresponding gravitational parameters --------------------------------------------------------------------------
