Hello there! Jump gates made by the precursors is the way to go from one system to another in the Coriolis-setting. The interesting point tough is that it can go very wrong going through these portals from the ship being damaged to madness. So its recommended to have a skilled pilot and a skilled smart guy doing the calibrations, a prayer to the Icons always helps too. Other ways too go trough exists also.
Oh almost forgot that you need to have stasis-beds on your ship when you make the jump or madness is sure to follow
