PNI Sensor Exhibits AHRS Apps at AUVSI 2012

PNI Sensor demonstrates TRAX Attitude & Heading Reference System’s (AHRS) field-proven applications during Association for Unmanned Vehicle Systems International North America, AUVSI 2012.

AHRS is the first high precision and cost-effective sensor system effective for use in unmanned, water- and land- based vehicles and robot applications. Constructed based on PNI’s extended expertise, the new TRAX AHRS modules ensure precise heading readings while encountering magnetic distortion and during motion.

The integration of high sensitivity sensors and complex Kalman-filtering algorithms enable TRAX to perform excellently. The TRAX incorporates high efficiency magnetometers having PNI-based filtering expertise with motion tracking systems and magnetic field sensors. Based on this integration capability, TRAX can recognize the presence of transient magnetic distortion, followed by stabilization and delivering accurate heading outputs. In contrast to standard AHRS, TRAX includes +/-2º heading accuracy during motion or while encountering magnetic materials. TRAX provides dynamic heading accuracy while operating in magnetically-compromised scenarios. This favors the operational performance of robots and unmanned vehicles while navigating within landscapes of metal detritus and unknown matter, and buildings.

The economic feature of TRAX modules allow a range of applications such as handheld surveying and targeting systems, ground robots, underwater vehicles, and in magnetic materials-present environments. TRAX for instance allows ROVs to have a stable accurate heading near hulls and oil rigs, and pipelines. TRAX can also be effectively deployed for Homeland security projects, University projects, and various commercial applications. TRAX modules have already started being shipped in May.

As part of Association for Unmanned Vehicle Systems (AUVSI), PNI demonstrates from August 6th to 8th, 2012 at the Mandalay Bay in Las Vegas.
