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.

TRAX2

PNI TRAX2 AHRS & Digital Compass

TRAX2 is the only orientation module that provides two different modes: AHRS or digital compass. TRAX2’s dual-mode capability supports a wide range of applications including drones, robotics, ocean buoys, manned and unmanned vehicles. TRAX2 combines PNI’s high sensitivity magneto-inductive sensors with a high stability 3-axis MEMS accelerometer to provide accurate heading information under a wide variety of conditions and the ability to overcome errors caused by changes in the local magnetic field. This provides no drift, high accuracy heading, pitch and roll and long-term static accuracy.

 

Key Features:

  • AHRS mode incorporates PNI’s 15 state Kalman filter with user-adjustable knobs to optimize the algorithms for specific applications and conditions
  • Gyro-stabilized compass for improved dynamic accuracy provides sub-0.5 degrees of heading accuracy • Low latency and no overshoot for quick target acquisition
  • Multiple calibration methods ensure accuracy in a wide range of industrial, scientific, marine and military applications
  • ITAR-free
