  Conversion of position & velocity in spherical coordinates
  to Cartesian coordinates (single precision)

  Given:
     A     r      longitude (radians)
     B     r      latitude (radians)
     R     r      radial coordinate
     AD    r      longitude derivative (radians per unit time)
     BD    r      latitude derivative (radians per unit time)
     RD    r      radial derivative

  Returned:
     V     r(6)   Cartesian position & velocity vector
