PNI Field Force AHRS TRAX modules

Introducing the first af ordable AHRS that stays on track while moving and through magnetic distortion.

Unmanned vehicles are performing progressively more complex tasks – and requiring increasingly robust and accurate heading and orientation information.  But existing AHRS modules leave too much room for error.  They lose heading when encountering magnetic distortion; they suffer from errors when experiencing erratic motion; and often don’t provide accurate headings, even in a static environment. And at more than $2000 for a MEMS-based AHRS, it’s no wonder AHRS have only been integrated by a select few customers.

So when there’s no room for error, Trax stays on track.

he new FieldForce Trax AHRS provides unparalleled heading accuracy when static, while moving and through magnetic distortion.  Trax employs a patented Kalman filtering algorithm that intelligently fuses PNI’s patented Reference Magnetic Sensors with gyros and accelerometers to overcome errors due to erratic motion and changes in the local magnetic field.   And Trax is priced for commercial use — delivering more reliable heading than AHRS modules that cost twice as much.Features: • High Accuracy•Magnetic distortion compensation• Multiple field calibration options•  Low power consumption•  RS232 and USB interface• RoHS compliant•  Backward compatible footprint
