.. py:function:: vallado(k, r0, v0, tof, *, numiter)

   high level implementation of Vallado's method (see also core/propagation)


.. py:class:: ValladoPropagator(numiter=350)

   Propagates Keplerian orbit using Vallado's method.

   .. rubric:: Notes

   This algorithm is based on Vallado implementation, and does basic Newton
   iteration on the Kepler equation written using universal variables. :cite:t:`Battin1999`
   claims his algorithm uses the same amount of memory but is between 40 %
   and 85 % faster.
