What are the base station trackers used for the HTC Vive called?

The base station trackers used for the HTC Vive are called Lighthouse. Lighthouse uses a system of lasers to track the position and movement of the HTC Vive headset and controllers in a room. The lasers emitted by the base stations sweep vertically and horizontally, creating a grid-like pattern of infrared light in the room. The sensors on the HTC Vive devices then detect this light and use it to calculate their precise position and orientation in real-time, enabling accurate and immersive virtual reality experiences.
