Like many high tech companies, Ascension grew from humble origins. To read how the company evolved from a two man entrepreneurial start-up to world class maker of 3D tracking devices for global markets, click the magazine cover.

3D tracking is Ascension’s only business. We make 16 tracking products employing four proprietary technologies. From tracking a head in a cockpit with a 25 mm wide sensor to guiding a catheter in a blood vessel with a 0.3 mm wide sensor, we have the right product for your application.

Ascension’s tracking and 3D guidance products precisely capture human and instrument movements in free space.

Our new 3D Guidance product line precisely tracks instruments, objects, and human motions for real-time interaction, 3D localization and volumetric measurments.

Our trackers are used worldwide in six markets. Clockwise, from top left, military target acquisition, flight simulation, real-time visualization, biomechanics, computer animation, and surgical navigation.

For 22 years, we have been developing trackers to meet emerging needs. We started with helmet tracking for tactical aircraft and simulators and moved on to virtual reality and computer animation, and now we have perfected a line of guidance and navigation devices for image guidance in minimally invasive medical procedures.
