'''[[Base Stations]]''' - the dual Beacons, also known as Base Stations, are part of the [[Lighthouse]] tracking system of SteamVR. These small, rectangular objects are placed in the opposite corners of the room, near the ceiling. They serve as reference points that enable the [[positional tracking]] of your HMD and SteamVR controllers within the 3D space. The Beacons Base Stations enable Lighthouse to track your head and hands with accuracy, low latency and sub-millimeter precision within a specified space (currently about 15 by 15 feet).
