Fastrak is a 3D magnetic tracking system made by Polhemus. The name means "fast track".
FastTrak was used in most VPL systems. It was also used in the first generation Virtuality systems.[1]
The sources and sensors for the fastrak are compatible with Polhemus Patriot SEUs.
Specs
These are the specifications for one of the Fastrak systems.[2]
