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

\Glspl{artificial satellite} are rocks with modems.

\section{SatNOGS DB}
The SatNOGS DB is a database that lists satellites,
many of which can be tracked by network operators.

\end{figure}

Individual satellites can be viewed, such as the RamSat CubeSat.

For some satellites, telemetry is available in a Grafana dashboard.
See the RamSat telemetry dashboard.

\section{Libre Satellites}
Satellites in orbit, decayed, or designs on Earth that generally support the libre way.
Select libre satellites:

\begin{itemize}
  \item UPSat --- First libre open source hardware and software satellite in the world.
  Created by the \gls{LSF}. \\
    \url{https://upsat.gr/}
\end{itemize}

        \caption{UPSat Website.}

\Gls{RF} Observations can be scheduled on the SatNOGS network.
See XXX for a sample list of observations of the RamSat CubeSat.

\begin{figure}[h!]
        \includegraphics[keepaspectratio=true,height=1.10\textheight,width=1.00\textwidth,angle=0]{satnogs-obs-list-ramsat-web.png}

        \index{RamSat}\index{observation}\index{CubeSat}
\end{figure}

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