OS3D-FG High Performance Miniature Orientation Sensor

OS3D-FG High Performance Miniature Orientation Sensor by Inertial Labs is a multi-purpose miniature 3D orientation sensor — Attitude and Heading Reference System. It is designed for use in real-time orientation tracking applications. It includes three types of sensing elements: tri-axial MEMS Gyroscopes, tri-axial high precision MEMS Accelerometers, and tri-axial Fluxgate Magnetometers.

The OS3D-FG also come equipped with an onboard processor and embedded orientation algorithms allowing for direct integration into systems without interfacing a PC. Additionally, OS3D-FG comes with hard and soft 2D and 3D magnetic calibration algorithms make the OS3D-FG eliminate the magnetic influence in the magnetic interference environment.

It provides better than 0.5 deg in Heading, 0.2 deg in Attitude accuracy. It is an affordable miniature Attitude and Heading Reference System that determines absolute orientation (heading, pitch, roll, and heave) for any device on which it is mounted for land, marine and aerospace applications.

View Data Sheet

Data from the Gyroscopes, Accelerometers, and Magnetometers, as well as the internal temperature sensor are gathered and processed by the on-board digital signal processor (DSP). The fusion algorithm processes these data and outputs the final orientation solution directly from the sensor. Data of the following types can be requested: raw inertial sensors data and/or quaternion data.

Each OS3D-FG module is individually calibrated in a special non-magnetic laboratory where reference acceleration, angular rates, and magnetic fields are applied to the device and measured at constant temperature. Additionally, temperature cycling is performed to obtain temperature calibration parameters for the gyro and accelerometer elements. Once fielded, OS3D-FG is able to be customer calibrated against soft and hard-iron interference present in the end application.
