The 3DM-CV5-AHRS is the smallest and lightest industrial AHRS with an Adaptive Kalman Filter available.
It features a fully calibrated and temperature-compensated triaxial accelerometer, gyroscope, and magnetometer
to achieve the optimum combination of measurement qualities under all dynamic conditions.
Additionally, the dual on-board processors run an exclusive Auto-Adaptive Extended Kalman Filter (EKF)
for outstanding dynamic attitude estimates, making it ideal for a wide range of applications, including
platform stabilization, autopilots, robotics, and vehicle health and usage monitoring.
The 3DM-CV5 family of industrial-grade, board-level inertial sensors provides a wide range of triaxial inertial
measurements, computed attitude, and navigation solutions. The Inertial Measurement Unit (IMU) includes direct
measurement of acceleration, angular rate, Delta-theta, and Delta-velocity. Compensation options include automatic
compensation for magnetic anomalies, gyro and accelerometer noise, and noise effects.
In models that include computed outputs, sensor measurements are processed through an auto-adaptive estimation filter
algorithm to produce high-accuracy computed outputs under dynamic conditions. The computed outputs vary between
models and can include roll, pitch, and yaw. All sensors are fully temperature-compensated and calibrated over the
operating temperature.
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 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.
