A Station that acts like a Hyper Drive Anchor. It wouldn't increase your range other then to its own sector.
The Anchor Station could add X range per station size.
Example: If you are 30 sectors away from your anchor stations sector, with a ship range of 20 and a +10 station, it would allow you to make the jump in one go. but not the 9 sectors between your max range of 20 and the stations sector.
