Overview

Software Release 1.7.6 - 29 June 2019

Logo

The µINS GPS aided Inertial Navigation System, µAHRS Attitude Heading Reference System, and the µIMU Inertial Measurement Unit monitor many different types of measurements including rotation, acceleration, GPS position, magnetic flux density, pressure and velocity. The Inertial Sense SDK provides a software interface to allow communication with the device including setting configuration options, retrieving specific data, and listening for data broadcasts.

μIMU, μAHRS, and μINS Description

The μIMU™ is a miniature calibrated sensor module consisting of an Inertial Measurement Unit (IMU), magnetometer, barometer, and L1 GPS (GNSS) receiver. Data out includes angular rate, linear acceleration, magnetic field, barometric altitude, and GPS WGS84 geo-position. All systems include a comprehensive sensor calibration for bias, scale-factor, and cross-axis alignment, minimizing manufacturing variation and maximizing system performance.

The μAHRS™ is an Attitude Heading Reference System (AHRS) that includes all functionality of the μIMU™ and fuses IMU and magnetometer data to estimate roll, pitch, and heading.

The μINS™ is a GPS (GNSS) aided inertial navigation system (GPS-INS) module that includes all functionality of the μIMU™ and provides orientation, velocity, and position. Sensor data from MEMs gyros, accelerometers, magnetometers, barometric pressure, and GPS/GNSS is fused to provide optimal measurement estimation.

The patent-pending package is smaller than 3 stacked dimes and fits into most industrial and commercial application designs.
