Installation Instructions for the
Transportation Attitude Reference Sensor
TARS Series
1.0 GENERAL INFORMATION
Honeywell's Transportation Attitude Reference Sensor (TARS)
Interial Measurement Unit (IMU) is designed to provide motion
sensing through 6 degrees of freedom and reporting of
angular rate, acceleration, and inclination data through a CAN
J1939 interface. It is packaged for harsh environments and
demanding applications.
Sensing and Internet of Things
2.0 CALIBRATION
TARS-IMU devices are aligned to a lat surface and calibrated
on an aerospace-grade rate table providing consistency
between units and eliminating the customer's need to calibrate
the IMU.
3.0 INSTALLATION
Mount the sensor using the three mounting holes and three
non-magnetic, stainless-steel socket head cap screws, M8 or
equivalent. Torque to 20 Nm ±2 Nm.
• Mating connector: AMPSEAL 16 Series, 776487-1 for 18-16
AWG conductors or 776524-1 for 20-18 AWG conductors
• Mounting direction: +Z
