The Transportation Attitude Reference Sensor or TARS-IMU is a packaged sensor array designed to report vehicle angular rate, acceleration, and inclination for demanding applications in industries such as heavy duty, off-highway transportation.

TARS-IMU enables autonomous vehicle characteristics and enhances efficiency and productivity by reporting key data required to automate and monitor movements of vehicle systems and components. The sensor fusion algorithm can be customized for specific vehicle applications through on-board firmware, allowing movement data to be filltered for extraneous environment and vehicle movements.

With two sensor models for different power levels, TARS-IMU accommodates both 5 V and 9 V to 36 V vehicle power systems. While communication is carried to the vehicle through industry standard CAN J1939 connectivity.

As a standard, TARS-IMU is calibrated on aerospace-grade rate tables at the factory to provide calibration consistency between units.

The TARS-IMU is customizable using the software downloads available on this page.
