Honeywell Transportation Attitude Reference Sensor, TARS series

Honeywell Sensing and Controls’ 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 filtered 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.  


  • High performance IMU, reports vehicle angular rate, acceleration and inclination (6 degrees of freedom) 
  • Ruggedized PBT thermoplastic housing design for the most demanding applications and environments (IP67 & IP69K certified) 
  • Advanced filtering of raw sensor data to minimize unwanted noise and vibrations, improves positioning accuracy 
  • Optional metal guard for added protection 
  • Supports 5 V and 9 V to 36 V vehicle power systems 
  • Operating temperature of -40 °C to 85 °C [-40 °F to 185 °F] 
  • Reduced power consumption 
  • Small form-factor 
  • Flexible. On-board firmware can tailor TARS-IMU to the specific vehicle and the specific application. 
  • Durable. With top-of-the-line sealing (IP67, IP69K) TARS-IMU is ruggedized to withstand harsh or heavy-duty applications 
  • Convenient. TARS-IMU can be pre-configured at the Honeywell factory for immediate installation out of the box, or it can be delivered with customizable firmware that allows you to use a single part number across vehicles and applications 
    • Designed to allow vehicle manufacturers and end users to increase efficiency with the automation of repetitive movements or complex tasks 
    • Enables precise movement, actuation and guidance over severe terrains and vehicle grades 
    • Enhances safety through enablement of monitoring and guidance capabilities that improve productivity of operators
