Teleport pod

Teleport pods were devices used by the Sontarans during the Sontaran invasion of Earth in 2009.

The pods resembled large cubes with platforms and small activation consoles inside. A pod's machinery was vulnerable to sonic waves but could be repaired quickly with a Sontaran baton.

Small beacons were also used in the campaign. These resembled discs and could be attached to surfaces, allowing the Sontarans to teleport things onboard their ship. (TV: The Sontaran Stratagem / The Poison Sky)

After the invasion was repelled, the pods came into the possession of UNIT. This led to the creation of Project Indigo. (TV: The Stolen Earth)

It is possible that the teleport pod is a technology related to the osmic projector. (TV: The Time Warrior), (PROSE: Lords of the Storm)

Locations
Teleport pods were located in the ATMOS factory, Rattigan Academy and on the Sontaran flagship. Transport was possible between all three. (TV: The Sontaran Stratagem / The Poison Sky)
