Heading Sensors - TRAX2 - AHRS & Digital Compass Module
TRAX2 Attitude & Heading Reference System (AHRS) & Digital Compass Module - Part no. 14387
|
TRAX2 AHRS & digital compass module provides unparalleled heading accuracy – even when GPS is not available.
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, among others.
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.

TRAX2 incorporates PNI’s military grade magnetic sensors with proven sensor fusion and digital compass algorithms to provide accurate direction and orientation without the assistance of GPS.
Mission critical applications require accurate heading in any environment, moving or still, with or without GPS. Heading can be determined with a digital compass in a magnetically clean environment or with GPS when moving.
TRAX2 is the only AHRS in its class that continuously corrects for gyro drift and provides absolute heading without any additional input such as GPS. Its patented magnetic anomaly rejection algorithms automatically isolate the earth’s magnetic field from other stray magnetic fields enabling accurate heading in any environment.
