The SatNOGS Optical Unofficial Guide documents how to set up and run an
|
|
\gls{optical-ground-station} for the \gls{LSF}'s \gls{SatNOGS} network.

\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 satellites and existing \gls{RF} ground stations
|
|
will be followed by a big picture view of acquiring and processing
|
|
images of satellites. Hardware is reviewed, then software to run
|
|
on it, with many options, including what is best. Finally,
|
|
what to do with the data (idk!).
|
|
The chapters that follow are listed below.
|
|
|
|
% Perhaps more LaTeXy ref XXX
|
|
\begin{itemize}
|
|
\item Satellites --- What are we looking at?
|
|
\item Ground Stations --- How Earth talks to satellites and back.
|
|
\item Toolchain and Process --- The big picture of what
|
|
hardware and software is needed to set up an optical ground station
|
|
for use on the distributed network.
|
|
\item Hardware --- Details on appropriate hardware configurations,
|
|
and example setups.
|
|
\item Software --- A look at the myriad software related to satellites,
|
|
and what works best at present for SatNOGS Optical.
|
|
\item Acquire --- Convert photons to bits. Pointing a camera at the
|
|
sky works.
|
|
\item Solve --- Pictures of stars reveal the time and location of
|
|
the photo. Plate solvers reviewed.
|
|
\item Detect --- The plate solver says where the photo is,
|
|
now detect if are there moving tracks that aren't stars that could
|
|
be satellites.
|
|
\item Identify --- With time, location, satellite detection, \glspl{TLE}
|
|
are overlaid and compared with detected satellites.
|
|
Satellite identification by computers and humans.
|
|
\item Upload --- When ready, data will be pushed to the SatNOGS network.
|
|
\item Support --- Where development is occurring and questions answered!
|
|

\section{SatNOGS Network}
|
|
SatNOGS is the \gls{LSF}'s global network of satellite ground stations.

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