NO ROOM FOR ERROR.
Introducing the first affordable AHRS
that stays on track while moving and
when encountering 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.

When there’s no room for error, TRAX stays on track.
The new FieldForce Trax AHRS provides
unparalleled heading accuracy when static,
while moving and when encountering
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.
