Inertial Labs OS3D-FG 3D Orientation Sensor

Manufacturer: | Categories: ,

The OS3D-FG from Inertial Labs is a multi-purpose miniature 3D orientation sensor, 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 miniature 3D motion sensor from Inertial Labs comes equipped with an onboard processor and embedded orientation algorithms allowing for direct integration into systems without interfacing a PC. Additionally, the OS3D-FG comes with hard and soft 2D and 3D magnetic calibration algorithms make that eliminate the magnetic influence in the magnetic interference environment.

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 accelerations, 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.
