\section{Overview of Satellites}
\label{sec:overview-satellite}

This chapter gives a brief overview of \glspl{satellite}, with particular
antention to ones using \gls{amateur-radio} bands.


\section{SatNOGS DB}
\label{sec:satnogs-db}

The \gls{SatNOGS-DB} is a database that lists \glspl{satellite},
many of which can be tracked by \gls{ground-station} operators on the
\gls{SatNOGS} network.

        \caption{\gls{SatNOGS-DB} website.}
        \label{fig:satnogs-db-web}
	\end{framed}
\end{figure}

Individual \glspl{satellite} can be viewed, such as the RamSat \Gls{cubesat}.

        \index{RamSat}
	\end{framed}
\end{figure}

For some \glspl{satellite}, \gls{telemetry} is available in a \gls{Grafana} dashboard.
See the RamSat \gls{telemetry} dashboard.

\section{Libre Satellites}
\label{sec:libre-satellites}

Below are \glspl{satellite} in \gls{orbit}, decayed, or designs on Earth that generally support the \gls{libre} way.
These are some select \gls{libre} \glspl{satellite}:

\Gls{RF} Observations can be scheduled on the SatNOGS network.
See figure \ref{fig:satnogs-obs-list-ramsat-web}, page \pageref{fig:satnogs-obs-list-ramsat-web}
for a example list of observations of the RamSat \Gls{cubesat}.%

Individual \gls{RF} observations are uploaded to the \gls{SatNOGS} network,
as can be seen in the example observation of the RamSat \gls{cubesat} by \gls{SatNOGS}
\gls{ground-station} ``2380 - Piszkesteto \gls{UHF}'' run by volunteer bcsak (username).
