Aceinna has launched the new Aceinna OpenIMU330B, a microelectromechanical systems (MEMS) based, small form factor high-performance 6-DOF inertial measurement unit that enables autonomous vehicles to accurately stay on track during turns and complicated maneuvers. Measuring only 11 mm x 15 mm x 3 mm, the Aceinna OpenIMU330B is designed for use in automotive advanced driver-assistance systems (ADAS) and autonomous 
Source: Aceinnasystems as well as for electronic stability control and lane keep assist functions.
The OpenIMU330B triple-redundant sensor architecture consists of three independent, three-axis accelerometer and three-axis gyros for excellent accuracy and reliability. By embedding a triple-redundant sensor array, the OpenIMU330 is able to use Aceinna’s proprietary voting scheme to utilize only valid sensor data. Any defective sensor output or errant dataset can be ignored or de-rated in importance. This architecture ensures the highest possible quality level and simultaneously improves the performance. The Bias Instability and Angular Random Walk of the rate sensors are 2o/hr and 0.2 o/√hr.
The OpenIMU330 is powered by an ARM M4 CPU with a floating point unit. The OpenIMU330B module 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 and Ubuntu.
Technical features include a triple redundant, three-axis MEMS angular rate sensor, triple redundant, high performance three-axis MEMS accelerometer, open source tool chain and custom algorithms, ARM M4 CPU and built in 16-state open source extended state Kalman filter. The Aceinna OpenIMU330B also includes automotive grade ASIL-B version, SPI and UART interfaces, wide temp range, -40° C to 85° C, high reliability, and an open community and development support.
Development tools and embedded navigation applications can be quickly developed on PC, MAC and Ubuntu and deployed to run on OpenIMU hardware. Aceinna Navigation Studio developer tools and GUI are found on our developer site: developers.aceinna.com
