\section{Overview of Satellite Identification}
\label{sec:overview-identify}
\index{identification}
\index{SIDLOC}
The \gls{LSF} is developing a project called \gls{SIDLOC},
for \gls{satellite} identification and localization. With the
addition of many more \glspl{satellite} in \gls{orbit} there is a growing need
for \gls{SSA}.


\section{\texttt{stvid}'s \texttt{process.py} for Identification}
\label{sec:process-identify}
The best tool for identifying \glspl{satellite} from \gls{FITS} files
is the \texttt{process.py}
script from \texttt{stvid}, available here:

* \url{https://github.com/cbassa/stvid}

My fork is here:

\section{Identifying Satellites with \texttt{satid}}
\index{satid}\index{sattools}

The deprecated C application, \texttt{satid} from the \texttt{sattools}
package can help identify \glspl{satellite}.
See figure \ref{fig:satid-giza-3}, page \pageref{fig:satid-giza-3}
for output from my Giza port of \texttt{satid}.%

\section{AstroImageJ}

\index{identify}\index{AstroImageJ}\index{FITS}
Analyze data with applications, such as \gls{AstroImageJ}.

\gls{FITS} files are commonly used  in astronomy.%
\footnote{\cite{Wiki22:fitswikipfreeencyc}}
\gls{AstroImageJ} can read \gls{FITS} format files.
See
\ref{fig:astroimagej}, page \pageref{fig:astroimagej},
for a screenshot displaying a \gls{FITS} file generated by
\texttt{\gls{stvid}}.
