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

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}.%

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} \gls{rotator}.
|
|
\glspl{SDR} can be used as \gls{RF} receivers.%

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

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