Spacegate

"It's in space!."

- John Sheppard

Spacegates are Stargates suspended in space, or in planetary orbit, particularly in the Pegasus galaxy. They have around them three power nodes, which power them and act as stabilizers to keep them in orbit. Even if knocked a considerable distance, these nodes will quickly reposition the Spacegate. Spacegates were taken from uninhabited planets to form the McKay/Carter Intergalactic Gate Bridge.

Instead of using a connected DHD, dialing is accessed by a panel on a ship. Puddle Jumpers and Wraith Darts are the only known vessels equipped with such DHDs, and are among the few ships capable of actually going through this type of Stargate.
