Player-run corporations that claim sovereignty over two null sec systems within range of each other can also set up a jump bridge at a player owned starbase (POS) that is in orbit of a moon. Jump bridges allow instantaneous travel to the other system's jump bridge, at the cost of using fuel (requiring supply by the owning corporation) scaled to the mass of ships that use them. This also leads to the accumulation of jump fatigue. As the aging POS systems & code have been phased out of the game, a deployable structure has effectively replaced the old jump bridge. However, unlike the old POS jump bridges, it allows players to customize who may use the gate based on settings such as standings or corporation / alliance affiliation. It also does not need to be deployed in a POS, and as such is often deployed near player owned Citadel structures.
