% Generate the moon vector in an earth or spacecraft centered frame. The earth-centered inertial frame is default or, if a spacecraft vector is input, the vector is in the spacecraft centered frame. This is the moderate precision model. See also MoonV1. Since version 1. -------------------------------------------------------------------------- Form: [u, r] = MoonV2( jD, rSc ) -------------------------------------------------------------------------- Inputs ------ jd (:) Julian date rsc (:) Spacecraft vector in the ECI frame (km) ------- Outputs ------- u (3,:) Unit moon vector r (:) Distance from origin to moon (km) --------------------------------------------------------------------------
