Two Solutions in One
The PATRIOTTM is a 3D digitizer and a dual sensor motion tracker, making it perfect
for a wide array of applications requiring medium resolution, accuracy, and range.
Computing the position and orientation of a small sensor as it moves through space,
provides dynamic, real-time measurements of position (X, Y, and Z Cartesian
coordinates) and orientation (azimuth, elevation, and roll).
Real-time Measurement
Measuring position and orientation in real time, the PATRIOTTM can update data
continuously, discretely (point by point), or incrementally. You can mount up to two
sensors on head or hands to capture real-time data for virtual reality or simulator
environments. With the optional stylus, you can trace the outline of a physical object or
collect polygon facets and get pinpoint accuracy of unlimited X, Y, and Z data points.
A/C Magnetics
Quiet and stable, the system is essentially unaffected by facility power grids. Update
rates are always maintained, as A/C magnetics offer the best signal-to-noise ratios and
incorporate sophisticated digital signal processing capabilities. In addition, adaptive
filtering is available as a standard feature.

Components |
|
|
The PATRIOT system includes a System Electronics Unit (SEU), a power supply, one sensor, and one source. You can expand the system’s capabilities simply by adding an additional sensor.
System Electronics Unit
Contains the hardware and software necessary to generate and sense the magnetic fields, compute position and orientation, and interface with the host computer via an RS-232 or USB 1.1 interface.
Source
The source contains electromagnetic coils enclosed in a plastic shell that emit the magnetic fields. The source is the system’s reference frame for sensor measurements.
Sensor
The sensor contains electromagnetic coils enclosed in a plastic shell that detect the magnetic fields emitted by the source. A lightweight cube, the sensor’s position and orientation is precisely measured as it is moved. The sensor is completely passive, having no active voltage applied to it.

Features |
|
|
Cost Effective
Provides position/orientation data at a minimum cost.
Ease of Use
Install and operate in minutes.
Multiple Output Formats
Position in Cartesian coordinates (inches or
centimeters); orientation in direction cosines,
Euler angles, or quaternions.
Multiple Sensor Operation
Permits measurement of up to two sensors with
a single system. No additional electronic units
are required.
Reliable
Factory calibrated, never needs adjustment.
New Option
PATRIOTTM Drive Bay, the new 6DOF tracking product that installs quickly and will fit into any standard PC Drive Bay and allow up to two tracking sensors and one electromagnetic source. This new format permits the user to embed the tracker directly within their PC, allowing for a more simplified workspace while maintaining the high accuracy’s associated with the standard PATRIOT tracker.
The PATRIOTTM Drive Bay continues to have the same accuracy and other specifications as the regular PATRIOT; speed of 60 Hz per sensor, and ease of use via an intuitive Graphical User Interface (GUI).

Applications |
|
|
Virtual Reality: From the beginning, Polhemus 3SPACE® systems have been the top choice for
VR head and body tracking. PATRIOT does it all for less.
Head-mounted Displays: A high quality military, VR, and simulator solution, PATRIOT is also the
most economical.
Biomechanical Analysis: Collect real-time relative movement data for gait and limb analysis. Perfect for leg, knee, joint, spinal, or shoulder rotational movement.
Graphics: Easily changes and controls the lighting of computer generated images in real time,
with the ability to move objects on screen without the loss of environmental changes (i.e., lighting and shadowing).
Stereotaxic Localization: Mounted on any non-metallic object (such as a robotic prosthesis), the sensor
determines its position and orientation.
CAD Database: Perfect low cost tool for developing databases of complex, non-metallic objects for
CAD, CAE, computer graphic models, or simulation with optional stylus.
Dimensional Archiving:
Collect the actual dimensions of artifacts, archaeological items, museum sculptures,
and other items.

|
Rhinoceros®
Rhinoceros is a registered trademark of Robert McNeel & Associates
|
Rhino software plug-in for the PATRIOT™, a 6DOF tracking system, that when used in conjunction with the Polhemus stylus, turns the system into a hand-held, free-form digitizer.
Once PATRIOT digitizes an object, Rhino can create, edit, analyze, and translate NURBS curves, surfaces, and solids in Windows®.
