\section{Overview of Ground Stations}
\label{sec:overview-groundstations}

Ground Stations.

\subsection{SatNOGS Ground Stations}
The Libre Space Foundation built the SatNOGS network using distributed,
volunteer-run, radio frequency ground stations, such as in
figure \ref{fig:spacecruft-rotator}, page \pageref{fig:spacecruft-rotator}.%
\footnote{\scriptsize{\url{https://spacecruft.org/assets/i/spacecruft-rotator.png}}}
It shows a SatNOGS ground station with VHF (right) and UHF (left) antennas
on a mast with Alt/Az rotator.

\subsection{SatNOGS Optical Ground Stations}
The Libre Space Foundation is developing a system to add optical ground
stations to the distributed network.

Prototype optical ground stations are being developed. An example
setup, using a Skywatcher EQ6-R Pro telescope tripod and tracking mount,
can be seen in Figure 
\ref{fig:video-enclosure-mount-tripod}, page \pageref{fig:video-enclosure-mount-tripod}.
