Inertial Labs OS3DM 3D Orientation Sensor

Manufacturer: | Categories: ,

The OS3DM from Inertial Labs is a multi-purpose sub-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 OS3DM sub-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, for PC-based integrations, the system comes with a set of libraries that allow the customer to modify algorithm and/or sensor parameters on-the-fly to more closely match the needs of individual applications.

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 OS3DM 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, OS3DM is able to be customer calibrated against soft- and hard-iron interference present in the end application.
