About PNI Sensor Corporation
We make the highest performance Magnetic Sensor
Over 100 million instances of PNI’s sensors are deployed
worldwide in combination with licensees
 Sensor design and production experience

We leverage our sensor’s performance and our mastery of
complex magnetic fields to create high accuracy,
reliable compass and motion tracking hardware and
software.

20+ years of expertise in solving real world magnetic
anomalies
 Robust Kalman filtering algorithms
 Expertise in sensor fusion/integration and testing

How is PNI’s technology different?
All of PNI’s products are based on Magneto-Inductive (MI)
sensor technology. The advantages of MI over other
magnetic sensing technologies include:
 Low power consumption
 Highly immune to electrical noise
 No drift or hysteresis
 Largest dynamic range
 Low latency
Developed specifically for compassing and motion tracking

government, military, and industrial applications.
Products measure from 2 – 9 axes:
 Trax AHRS

full 9 axes of measurement (mag, accel, gyro)
 FieldForce TCM

6 axes (mag and accel)
 TargetPoint DMC

ruggedized, mil-qualified DMC for targeting and range finding
 CompassPoint Compass Modules

FieldForce Trax AHRS
The new FieldForce Trax AHRS module provides
unparalleled heading accuracy when static and while
moving through magnetic distortion.
6

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.

Unparalleled static accuracy of .5° rms and dynamic
accuracy of 2.0°rms

Trax is priced for commercial use - delivering more reliable
heading than AHRS modules that cost twice as much.
FieldForce TCMs
High-performance, low power consumption,
tilt-compensated 3-axis electronic compass modules
that provide industry-leading heading accuracy.
Ideal for applications that require consistency and accuracy in
the field

Reliable, pinpoint-accurate pitch, roll and compass heading to
.3° rms
 Incorporates magnetic distortion compensation
 Four user-selectable calibration modes, as well as the ability to
recalibrate the accelerometers to ensure long-term accuracy
 Available in two different footprints and interfaces for easy
integration

CompassPoint Modules
Cost-effective, low-power compass modules for costsensitive products that historically could not justify such
well-featured digital compasses
Prime
 low cost, high-performing 3-Axis compass module
 eliminates the time and expense of building a compass
from scratch
 1° heading accuracy, 0.1° heading resolution
V2Xe
 full-featured 2-Axis compass module
 1° heading accuracy, 0.01° heading resolution when level
