NGIMU

High-performance, fully featured IMU for real-time and data logging applications

The Next Generation IMU (NGIMU) is a compact IMU and data acquisition platform that combines on-board sensors and data processing algorithms with a broad range of communication interfaces to create a versatile platform well suited to both real-time and data-logging applications.

High performance IMU/AHRS

On-board sensors include a triple-axis gyroscope, accelerometer, and magnetometer, as well a barometric pressure sensor and humidity sensor.  An on-board AHRS sensor fusion algorithm combines inertial and magnetic measurements to provide a drift-free measurement of orientation relative to the Earth.  Each device is individually calibrated using robotic equipment to achieve the specified accuracy.

Software

The NGIMU GUI can be used to configure settings, view real-time sensor data, perform calibration and export data to user software; e.g. Microsoft Excel. The NGIMU MATLAB library provides all the tools required to import, organise and plot data in MATLAB. User software can be developed using the NGIMU API.
