Transportation Attitude Reference System (TARS Series)

Ruggedized Inertial Measurement Unit (IMU)

DESCRIPTION

The Transportation Attitude Reference System or TARS-

IMU is a packaged sensor array designed to report vehicle

angular rate, acceleration, and attitude data 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.

DIFFERENTIATION

• 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

manufacturers to use a single part number across vehicles

and applications

FEATURES

• 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 and 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

POTENTIAL APPLICATIONS

• Equipment control • Linear position

• Linkage tracking • Bucket control

• Work monitoring • Vehicle stability control

• Operator assisted control

• Performance and output control

VALUE TO CUSTOMERS

• 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

SIX DEGREES OF FREEDOM

PORTFOLIO

TARS-IMU joins Honeywell’s venerated sensor portfolio, and

adds to the ever-increasing connected and intelligence driven

capabilities that Honeywell offers. TARS-IMU is built to survive

the demanding applications in industries like off-highway

transportation and beyond.
