Inertial Systems

Need help?

ACEINNA’s inertial systems provide end-users and systems integrators with fully-qualified MEMS based solutions for measurement of static and dynamic motion in a wide variety of challenging applications, including autonomous driving, avionics, drones, robotics, and precision agriculture.

ACEINNA’s success in developing innovative sensor modules and integrated sensing systems is the result of its combined expertise and intellectual property in sensor characterization, MEMS sensor integration algorithms, and application-specific requirements. In addition, ACEINNA’s inertial products are designed and tested to meet industry-standard and/or customer-specific environmental requirements.


  • In 2006, a typical IMU measured 12 cm on each side (1700 cm³). Today, ACEINNA’s latest IMU delivers higher accuracy and processing power from a module less than 1 cm³ in size, at 1/100th of the original cost.

  • The ACEINNA IMU380ZA inertial sensing module has been engineered to lead the way in precision agriculture applications, with a MTBF greater than 50,000 hours and low power consumption, all from a compact package that weighs less than 17 grams.

  • ACEINNA has shipped over 50,000 inertial systems for installation in heavy machinery and deployed inertial navigation units in over 600 types of aircraft.



The ACEINNA OpenIMU300ZA is an easy-to-use high-performance 9 DOF open inertial platform. The OpenIMU300 features a precision 3-Axis Accelerometer, low-drift 3-Axis Rate Gyro, and 3-Axis Magnetometer. The low-power platform is powered by a 168MHz ARM M4 CPU with a Floating Point Unit. The OpenIMU300 runs the OpenIMU open-source stack that includes an optimized full-state Kalman Filter for Attitude and GPS-Aided Position-Velocity-Time (PVT) measurement. A free tool-chain based on VS Code supports PC, MAC, Ubuntu.
