Stargate power node

In the Pegasus Galaxy, some Stargates have been placed in space in orbit of planets, rather than on their surfaces. Rather than using a connected DHD, space-based gates are powered by three power nodes, and dialing is accessed by a panel on a ship. Puddle jumpers and Wraith Darts are both equipped with such DHDs, and are among the few ships capable of going through the Stargate.
