6 Degree-of-Freedom Totally WIRELESS Tracking System with up to 16 Receptors.


The LIBERTY LATUS (Large Area Tracking Untethered System) represents a whole new dimension in tracking technology, one that offers a totally wireless, full 6 Degree-Of-Freedom solution. The system has speed, ease-of-use via an intuitive Graphical User Interface (GUI) and is capable of tracking up to 12 independent markers over large areas. Because of the improved signal-to-noise ratios, LIBERTY LATUS offers increased stability while providing consistent high quality data, all while being completely untethered.

LIBERTY LATUS provides truly wireless tracking. There are absolutely no wires - each marker is self-contained. The system is capable of tracking up to 12 markers for full 6 Degree-Of-Freedom solutions over large areas. Each marker is tracked in space by a receptor that covers up to an 8 foot (2.44m) diameter. Each system is capable of connecting up to 16 receptors for total coverage of hundreds of square feet. Systems may also be concatenated for even larger area coverage. All wireless communication is via a proprietary magnetic data link.


Totally wireless markers are completely self-contained, each housing a lithium ion battery assembly that  provides up to 2.5 hours of power. Each system may track up to 12 markers independently. 

Reduced Distortion

The system is capable of reducing any distortion effects normally seen with long range electromagnetic systems because of its short range distributed receptor architecture, and enhanced signal-to-noise ratio. 


Four receptor channels are available on the base product; the system is upgradeable to 8, 12, or 16 receptor channels within the same chassis by having additional circuit boards installed. Each receptor can cover up to 50 sq. ft. (4.7 sq m). 

Communications Interface

LIBERTY LATUS communicates via RS-232 serial or USB interface. Both are included in the base unit.

Multiple User Definable Profiles

The GUI allows for three independent user-definable profiles for setting system parameters such as filtering, output formats, coordinate rotations and much more.

Multiple Output Formats

Users may select position in Cartesian coordinates (English or metric); orientation in direction cosines, Euler angles or quaternions.
