FASTRAK®

The industry standard in motion tracking since 1994, FASTRAK is proven technology with real world credentials. Offering real time 6 Degree-Of-Freedom (6DOF) tracking with virtually no latency, the award-winning FASTRAK is prepared for any challenge. Use it for head, hand and instrument tracking, biomechanical analysis, graphics and cursor control, digitizing and pointing, stereotaxic localization, telerobotics and more. Capture your data with FASTRAK, the ultra-accurate, maximum reliability electromagnetic motion tracking system.

FASTRAK tracks the position (X, Y, and Z Cartesian coordinates) and orientation (azimuth, elevation, and roll) of a small sensor as it moves through space. The system's near zero latency makes it ideal for virtual reality interfacing, simulators and other applications where real time response is critical. FASTRAK is also well suited for biomechanical applications such as gait and joint movement analysis.

Expandable and Stable

FASTRAK is hugely expandable to accommodate a wide range of integration requirements. FASTRAK includes a system electronics unit (SEU), a power supply, one sensor and one source. For projects requiring multi-point tracking, you can connect up to four sensors to the SEU. Even more impressively, you can synchronize up to four FASTRAK systems to enable simultaneously tracking up to 16 sensors. FASTRAK offers a 120Hz update rate multiplexed among the connected sensors. It provides remarkable 4ms latency.

Adding a stylus converts your FASTRAK into a free form digitizer ideal for creating files that can be used in popular computer graphics programs. With the stylus, you can get pinpoint accuracy of unlimited X, Y and Z data points. Capturing data with the ergonomically designed stylus is as simple as pressing its button.

FASTRAK delivers exceptional stability as it's essentially unaffected by facility power grid fluctuations. Update rates are always maintained because AC magnetics offer superior signal to noise ratios. Sophisticated digital signal processing helps provide optimal signal. To further ensure unrivaled performance, adaptive filtering is available as a standard feature.

Easy Setup

After unpacking FASTRAK for the first time, the system will be up and running in just minutes. Simply install the included software, connect the FASTRAK to your PC's USB or RS-232 port, connect the sensor and source, power on, and you're good to go. Special FASTRAK synchronization circuitry yields reliable performance even when FASTRAK is used in close proximity to a CRT display.

Advanced AC Technology

Polhemus pioneered AC motion tracking and has refined and perfected the technology through numerous generations. Unlike products based on pulsed DC technology, Polhemus trackers are not negatively affected by the earth's magnetic field, power outlets or electric motors. Because AC tracking is also more accurate and faster, it's clearly the superior choice. In fact, Polhemus originated pulsed DC technology, but chose not to pursue it because of performance shortcomings.

There is no need to worry about maintaining a clear line-of-sight between the sensor and source. Unlike sonic or laser devices, FASTRAK is not affected by signal blocking and interference.
