\Glspl{ground-station} are a setup of equipment such as \glspl{embedded-system}, cameras,
|
|
\glspl{SDR}, \glspl{antenna}, and receivers, located on Earth, observing space.

\section{SatNOGS Ground Stations}
|
|
|
|
The \gls{LSF} built the \gls{SatNOGS} network using distributed,
|
|
volunteer-run, \gls{RF} \glspl{ground-station} using \glspl{SDR}, such as in
|
|
figure \ref{fig:spacecruft-rotator}, page \pageref{fig:spacecruft-rotator}.%
|
|
\footnote{\url{https://spacecruft.org/assets/i/spacecruft-rotator.png}}
|
|
It shows a \gls{SatNOGS} \gls{ground-station} with \gls{VHF} (right) and \gls{UHF} (left)
|
|
\glspl{antenna} on a \gls{mast} with an \gls{alt-az-mount} \gls{rotator}.
|
|
\glspl{SDR} can be used as \gls{RF} receivers.%

\Glspl{ground-station} can be viewed on the \gls{SatNOGS} network website, such as

as the example in figure \ref{fig:satnogs-ground-station-web}, page \pageref{fig:satnogs-ground-station-web}.%

\section{SatNOGS Optical Ground Stations}
|
|
|
|
The \gls{LSF} is developing \gls{SatNOGS-Optical} to add
|
|
\glspl{optical-ground-station} to the network.
|
|
|
|
Prototype \glspl{optical-ground-station} are being developed. An example
|
|
setup, using a Sky-Watcher EQ6-R Pro \gls{telescope} tripod and tracking mount,
|
|
\index{Sky-Watcher}\index{tripod}\index{mount}\index{enclosure}
|
|
\index{mount}\index{track}
|
|
can be seen in figure
|

\ref{fig:video-enclosure-mount-tripod}, page \pageref{fig:video-enclosure-mount-tripod}.
