Peacekeepers of the Vast/Jump drive

Jump Gates - Jump gates are permanent structures in N-space that can produce a stable jump window within a set volume. In fact, Jump Gates are always producing a very small jump window, small enough to maintain a graviton tether to a similar structure in H-Space. The H-space gate is referred to as a beacon or lighthouse by particularly romantic space travelers. The beacons communicate with other beacons at c_H allowing low bandwidth FTL communication, and will also allow an incoming window to be opened from H-Space

Bilateral Jump Drives - These drives are capable of opening a jump window from N-space or H-space, large enough for several ships to transit. They are typically found on capital ships and large mother freighters. All known ships require significant time to recharge the supercapacitors required to form a jump window.

Incoming Jump Drives - these drives are capable of safely and routinely opening a jump window from H-space to N-space but usually enter H-space only through jump gates or with the assistance of a larger freighter. Despite its name, an incoming jump drive is capable of creating an outgoing jump window. However, this will required the use of limited resources. Typically found on light and medium duty freighters, freighter captains have been known to skimp on maintenance for their emergency jump capabilities.

Drop drives - these drives are not capable of generating an outgoing or incoming jump window. Instead, the ships are dropped near gravity wells and are dragged into N-space as they fall down the jump gradient. Energy shielding from the drive allows this process to be accelerated and relatively controlled.
