Satellite Factories produce Navigation Relay Satellites from Energy Cells, Majaglit and Silicon Wafers.
NPC stations will buy Quantum Tubes as a secondary resource.
This stations manufactures Navigation relay Satellites. With the invention of sending information through the gate network, satellites were developed to assist in boosting these transmissions, scientists later added a small sensor network to the satellites to assist in navigation and long range managing of stations.
The factory uses delicate machinery to build these complicated small devices.
Note that despite Paranid Snail Ranch and Space Jewellery stations being the sole source of Majaglit needed for satellites, Paranid Satellite Factories are not seen in-game.
