 At present, for the \gls{SatNOGS} network \gls{RF} \glspl{ground-station},
 hamlib is typically used for tracking, if directional \glspl{antenna} are
 used. Hamlib was originally created for \gls{amateur-radio} equipment, but has

+\subsection{Hamlib}
 I don't know of anyone prototyping a satellite tracking mount with hamlib,
 but it should be possible using the ``leap frog'' method, perhaps on the
 same mount as existing \gls{SatNOGS} \glspl{antenna}. The mount may not
 be steady enough.
