No, each has their own tracking method.

Vive and Index use Infrared lasers emitted from the base stations and picked up by sensors on the controllers/headset. Each object does its own tracking and relays that to the PC.

OG Oculus Rift uses Infrared LEDs omitted by the controllers/headset and picked up by the cameras attached to the PC, the PC does the tracking.

WMR uses White LEDs on the controllers and the cameras on the headset pick up both those and the headset position based on object/surface detection. Not sure if the headset calculates its own position or not.

RiftS/Quest is similar to WMR but with Infrared LEDs.

(all these systems work in combination with accelerometer/gyro data)
