iNEMO sensor fusion

1.1

Overview

The iNEMO engine is a new, advanced software engine that fuses accelerometer,

gyroscope and magnetometer data to deliver accurate and reliable motion-sensing

information that is easy to integrate into smart consumer devices.

How the iNEMO engine works

The iNEMO engine fuses data from the integrated 9-axis sensor suite with advanced

algorithms that use true high-number-of-states adaptive Kalman filtering.

The iNEMO engine’s adaptive filters converge so that correct heading data overrides

magnetic distortions and anomalies, resulting in more accurate and reliable data.

iNEMO allows the correction of:

●

magnetic distortions registered on the magnetometers

●

dynamic distortion measured by the accelerometers

●

inherent drift of the gyroscope over time

The iNEMO engine integrates all 9 inertial axes plus compass with complex fusion

algorithms, so the output of the sensor cluster is optimized.

This allows for faster, easier integration into smart consumer devices and higher

performance of the solution as a whole.

The library can be configured to achieve the best trade-off between performance and power-

saving to match application requirements.
