3DM-CX5-AHRS
By MicroStrain by HBK
• Bias tracking, error estimation, threshold flags, and
adaptive noise modeling allow for fine tuning to
conditions in each application
• Accelerometer noise as low as 20 ug/√Hz
• Smallest and lightest industrial AHRS with Adaptive
Kalman Filter available
• SensorConnect enables simple device configuration, live
data monitoring, and recording
• The MSCL API allows easy integration with C++, Python,
.NET, C#, Visual Basic, LabVIEW and MATLAB
environments
• MIP open byte level communication protocol
• Automatic magnetometer calibration and anomaly
rejection eliminates the need for field calibration
• Automatically compensates for vehicle noise and
vibration
Description

3DM-CX5-AHRS
The MicroStrain 3DM-CX5 family of high-performance, industrial-grade, board-level inertial sensors provides a wide
range of triaxial inertial measurements, computed attitude, and navigation solutions.
In all models, the Inertial Measurement Unit (IMU) includes direct measurement of acceleration and angular rate, and
is fully temperature-compensated and calibrated over the operating temperature. The use of Micro-Electro-Mechanical
System (MEMS) technology allows for highly accurate, small, lightweight devices.
SensorConnect software is a user friendly program for device configuration. MIP Monitor (MicroStrain Inertial
Protocol) can also be used. Both packages provide for device configuration, live data monitoring, and recording.
Alternatively, the MIP Data Communications Protocol is available for development of custom interfaces and easy
OEM integration.
The sensor operates independent of computer platform, operating system, or coding language.
PRODUCT HIGHLIGHTS
• Triaxal accelerometer, gyroscope, and temperature sensors achieve the optimal combination of
measurement qualities
• Dual on-board processors run a new Auto-Adaptive Extended Kalman Filter (EKF) for outstanding dynamic
roll, pitch and yaw performance -
