Description

FIS1100 is the world‟s first complete consumer 6D

MEMS Inertial Measurement Unit (IMU) with sensor

fusion to specify system level orientation accuracy.

When using the FIS1100 in combination with the

supplied XKF3 9D sensor fusion, the system features an

accurate ±3° pitch and roll orientation, and a ±5°

yaw/heading typical specification.

The FIS1100 incorporates a 3-axis Gyroscope and a 3-

axis Accelerometer and can connect an external 3-axis

magnetometer through an I2C master thus forming a

complete 9DOF system.

The FIS1100 also incorporates an advanced vector

Digital Signal Processor (DSP) motion co-processor

called the AttitudeEngine™. The AttitudeEngine

efficiently encodes high frequency motion at high

internal sampling rates, preserving full accuracy across

any output data rate.

This enables the application to utilize low Output Data

Rates (ODR) or on-demand (host polling) and still

acquire accurate 3D motion data. The AttitudeEngine

allows reducing the data processing and interrupt load

on a host processor with no compromises in 3D motion

tracking accuracy. The result is very low total system

power in combination with high accuracy, which are

essential to many portable and battery powered

applications.

Applications

 Drone Flight Control and Gimbal Stabilization

 Optical Image Stabilization (OIS) and Electrical

Image Stabilization (EIS)

 Virtual Reality and Augmented Reality

 Robotic Orientation and Position Tracking

 Sport & Fitness Wearables

 Pedestrian Navigation and GNSS Augmentation
