OVERVIEW

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.


FEATURES

Wireless
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.

Scalable
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.


COMPONENTS

Wireless Marker:
Markers contain the electromagnetic source, control electronics and a rechargeable lithium ion battery assembly. The system reports the position and orientation of each marker that is within range of at least one receptor. The system is capable of accommodating up to 12 markers. The battery assembly provides power for approximately 2.5 hours and is easily removed for recharging. Markers weigh 2 ounces and are easily mounted on virtually anything including the body with our optional body mount kit.

Receptor:
Receptors contain electromagnetic receiving elements cast into a solid assembly that detects the magnetic signals emitted by the marker(s) for up to 8 feet (2.44m) in diameter. Cable length is 60 feet (18.3M0. This lightweight, small cube can be easily mounted to almost any surface. The system is capable of accommodating up to 16 receptors.

Systems Electronic Unit (SEU):
The SEU contains the hardware and software necessary to sense the magnetic fields generated by the markers, compute positions and orientation, and interface with the host computer via RS-232 or USB.
