Hybrid Technology 3D Motion trackers use combination of Technologies, like Ultrasonic, Active, Passive, Inertial, RFID and Vision processing etc.

PS Technologies Optical Motion Tracking Systems:

Personal Space Technologies makes real-time, robust, high precision, 6DOF 3D Motion Trackers and 3D Medical Visualization workstations.  

PST-Iris- The PST Iris is an optical measurement/tracking system that measures the 3D positions of either active or passive markers affixed to objects. Using this information, each PST Iris is able to determine the position and orientation of marked devices within a specific measurement volume. The PST Iris is an optical measurement system that allows you to transform any object into a 3D measurement device. Each IRIS tracker is able to work independently and can be connected with more trackers to create an even bigger measurement volume.

PST Base compact is a compact bar tracker 

Characteristics: Minimum tracking distance 20 cm, maximum tracking distance at least 3 m. 

The optical tracker PST Base tracks complex shaped objects, convex or concave. There is no requirement for all markers to be visible to the tracking system. Occlusion of a significant number of markers is handled without loss of tracking. In most cases objects have around 30 markers, typically only 8 are simultaneously visible to the tracking system. Even with such a small subset of visible markers the tracking system can calculate a 6 degrees of freedom (6DOF) position and orientation of the object. Teaching the optical tracker PST Base about new objects is easy. A simple training procedure allows the user to simply show a new object to the tracking system and within seconds these objects can be used for full 6DOF tracking. The optical tracker PST Base comes with an easy to use C SDK with bindings for C# and Python. Every PST Base is a fully independent tracking unit. Ready to go from the moment it comes out of the box. No calibration and no registration of cameras. Multiple PST Base’s can be connected to combine tracking spaces. A complete tracking system consists of one or more tracking units, marked targets and the PSTracking 4.0 application. The PST Base can be directly plugged into the system using USB 2.0. PST Base results can also be shared fully transparently over Ethernet. Simply install the client software on a second computer and connect.
