ComSat station

The ComSat Station is an add on to a Command Center, used for scouting and detection. Its primary ability requires the use of energy. It can execute a "Scanner sweep" and nothing else. Like all add on buildings, it is abandoned when the building moves.

The ComSat Station does not appear in StarCraft II, having been replaced by the Surveillance Station.

Scanner Sweep
The Scanner Sweep uses highly concentrated scanners to reveal an area, including cloaked or burrowed units. This can be executed anywhere on the map at any time. The circular view shown lasts for about 10 seconds before changing to the Fog of War static view. A scanner sweep is indicated to all players (including the one doing it) by a series of blue 4-pointed sparkles moving in a circle.
