TRAX2 Attitude and Heading Reference System (AHRS) & Digital Compass Module

 

The TRAX2 AHRS and DMC provides unparalleled heading and accuracy when static, while moving and when encountering magnetic distortion. TRAX2 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. This provides no drift, high accuracy heading, pitch and roll and long-term static accuracy.

TRAX2 provides two different modes: AHRS or digital compass. This dual-mode capability supports a wide range of applications including laser range finders, drones, robotics, manned and unmanned vehicles, and ocean buoys, among others.

Features & Benefits:

  • 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 in a wide range of industrial, scientific, marine and military applications
  • ITAR-free
