\section{Unofficial Guide Overview}
|
|
First, an overview of the this text, then the \gls{LSF}
|
|
and some of it's key projects, such as the \gls{SatNOGS} network.
|
|
A cursory review of \glspl{satellite} and existing \gls{RF} \glspl{ground-station}
|
|
will be followed by a big picture view of acquiring and processing
|
|
images of \glspl{satellite}. Hardware is reviewed, then software to run
|
|
on it, with many options, including what is best. Finally,
|
|
what to do with the data.
|
|
The chapters that follow are listed below.

\item [\Glspl{satellite}] --- What are we looking at?
|
|
\item [\Glspl{ground-station}] --- How Earth talks to \glspl{satellite} and back.
|
|
\item [\Gls{toolchain} and Process] --- The big picture of what
|
|
hardware and software is needed to set up an \gls{optical-ground-station}
|
|
for use on the network.
|
|
\item [Hardware] --- Details on appropriate hardware configurations,
|
|
and example setups.
|
|
\item [Software] --- A look at the myriad software related to \glspl{satellite},
|
|
and what works best at present for \gls{SatNOGS-Optical}.
|
|
\item [Acquire] --- Convert \glspl{photon} to bits. Pointing a camera at the
|
|
sky works.\index{camera}
|
|
\item [Solve] --- Pictures of stars reveal the time and location of
|
|
the photo. \Glspl{plate-solver} reviewed.
|
|
\item [Detect] --- The \gls{plate-solver} says where the photo is,
|
|
now detect if are there moving trails that aren't \glspl{star-trail} that could
|
|
be \glspl{satellite}.
|
|
\item [Identify] --- With time, location, \gls{satellite} detection, \glspl{TLE}
|
|
are overlaid and compared with detected \glspl{satellite}.\index{identify}
|
|
\Gls{satellite} identification by computers and humans.
|
|
\item [Upload] --- When ready, data will be pushed to the \gls{SatNOGS} network.
|
|
\item [Support] --- Where development is occurring and questions answered!

\section{Optical Network Status}
|
|
The \gls{SatNOGS} \gls{RF} network has been running successfully for years.
|
|
Adding a \gls{SatNOGS-Optical} network is a new development. At present there
|
|
are zero nodes on the network.
|
|
|
|
Some software already exists,
|
|
some is being ported from \gls{C} to \gls{Python}, and other parts remain to be done.
|
|
There is software available for acquiring optical data of \glspl{satellite}.
|
|
There is no facility at present for pushing data back to the network.
