I am new here and what to start developing with you guys
want to know where to start from
A good place to start would be checking out the SatNOGS wiki.
A lot of info can be found in the forum, many interesting tips and hits can be found in several topics in the forum.
If you prefer a more close to realtime interaction feel free to check the SatNOGS IRC channel on Freenode or the SatNOGS Matrix.org channel available via the web here:
