Teleport pod

Teleport Pods were utilised by the Sontarans during the Sontaran invasion of Earth in 2009.

The pods resembled large cubes with a platform and a small activation console inside. The pods machinery was vulnerable to sonic waves but could be easily repaired by a Sontaran baton.

Also used in the campaign were small beacons resembling discs that could be attatached to a surface allowing the Sontarans to teleport it onboard their ship. (DW: The Sontaran Stratagem / The Poison Sky)

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

It is possible that the Teleport Pod is a technology related to the Osmic Projector.(DW: The Time Warrior), (MA: 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. (DW: The Sontaran Strategem / The Poison Sky)
