Description

The MicroStrain 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 a 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 3DMCV5-AHRS is a value focused AHRS designed to balance cost and performance.

 

Use Cases

Antenna and Camera Pointing

Low-noise, low latency, and linear MEMS gyros and accelerometers result in accurate and stable attitude tracking

Rugged machined aluminum industrial packaging provides reliable performance in high-vibration and shock environments

Compact OEM versions for embedded applications permit lower cost without losing accuracy

Drone Navigation

Low-noise, low-drift MEMS gyros and accelerometers result in accurate and robust PVA (Position, Velocity, Attitude) outputs during sharp turns, high winds, etc.

Exceptional IMU performance and robust anomaly rejection by the EKF aids navigation under GNSS outage or denied environments

Fully calibrated and temperature compensated guarantees stable performance in outdoor operating temperature ranges even with high levels of fluctuation

Mobile Robotics

Low-noise, linear, and stable MEMS gyros and accelerometers enable superior heading accuracy during turns & bumps

Auto-adaptive Kalman Filter algorithms provide exceptional dynamic performance

Auto self-calibration and automatic anomaly rejection make units with magnetometer reliable and accurate heading reference

Fully calibrated and temperature compensated IMUs provide stable performance in demanding environments
