Includes production for low density structure and rocket control units. Rocket fuel is provided external. Satellites build on site.
known bottlenecks: copper plates! there are 5 blue belts of Cu plates input. You can't loose more than half a belt without slowing the system down...
The system produces *just* enough low density structure to keep it running. I suggest letting it saturate before you auto launch any rockets.
Only condition check used: the inserter providing the satellites for the rocket listens to the inserters that remove the bottles from the silo. If erer are bottles in the silo... no new satellite...
looks like this:
