  Conversion of position & velocity in spherical coordinates
  to Cartesian coordinates

  (double precision)

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

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