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

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

  Returned:
     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
