% Moderate precision sun model. Generates the sun vector in the earth-centered inertial frame. Will output the distance to the sun from the earth if two output arguments are given. SunV2 is computationally a little more intensive and gives more accurate results than SunV1 -------------------------------------------------------------------------- Form: [u, r] = SunV2( jD, rSc ) -------------------------------------------------------------------------- ------ Inputs ------ jD (:) Julian date rSc (3,:) Spacecraft vector in the ECI frame (km) ------- Outputs ------- u (3,:) Unit sun vector r (:) Distance from origin to sun (km) --------------------------------------------------------------------------
