Attitude Heading Reference Systems (AHRS)

Get superior performance with our nine-degree-of-freedom (9DOF) strapdown Attitude Heading Reference systems (AHRS) and modules with Kalman filter & attitude/heading algorithm for accurate roll/pitch/heading in dynamic environments.

The PNI TRAX attitude and heading reference system (AHRS) provides unparalleled heading and accuracy when static, while moving and when encountering magnetic distortion. TRAX employs a patented Kalman 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.

The new PNI TRAX2 AHRS & digital compass module incorporates PNI’s military-grade magnetic sensors with proven sensor fusion and digital compass algorithms to provide accurate direction and orientation in demanding conditions.

Aceinna’s & Memsic inertial systems provide end-users and systems integrators with fully-qualified MEMS-based solutions for measurement of static and dynamic motion in a wide variety of challenging environments including avionics, remotely operated vehicles, agricultural & construction vehicles and automotive test.

Aceinna is a spin-off of Memsic Inc. a world leader in MEMS sensor technology.

Current product offering includes the OpenIMU300ZA and AHRS440.
