\gls{Celestron} \glspl{telescope} are widely used and available for many years.
There is a variety of software written to control the mounts. The below list
covers the drivers (e.g. \gls{INDI}), not the software on top (e.g \gls{KStars}).

\subsection{INDI}
\gls{INDI} does much, \gls{KStars}, etc.
One option to consider is making \gls{stvid} an \gls{INDI} client.
\subsection{INDIGO}

This library implements the serial commands supported by the Celestron
NexStar hand control (HC) and SkyWatcher/Orion SynScan HC. This applies
to the Celestron: NexStar GPS, NexStar GPS-SA, NexStar iSeries, NexStar
SE Series, NexStar GT, CPC, SLT, Advanced-VX, Advanced-GT, CGE, CGEM etc.
SkyWatcher: EQ5, HEQ5, EQ6 (Pro), AZ-EQ5 GT, AZ-EQ6 GT, EQ8 etc. and the
corresponding Orion mounts.

\subsection{Antenna Tracking Software}
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
expanded to control many more devices.

\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.
\index{hamlib}\index{mount}\index{track}
Hamlib lists support for the following tracking mounts, usually
used with \glspl{telescope}.%
