OS3DM Subminiature 3D Orientation Sensor

The OS3DM Subminiature 3D Orientation Sensor by Inertial Labs is a board level, fully embedded absolute subminiature orientation sensor that combines sensor technologies of magnetometers, gyroscopes, and accelerometers to measure absolute orientation of any object.

Its internal microcontroller processes the data from nine discrete sensing axes through its sensor fusion algorithm and produces a quaternion orientation solution that is then provided over either UART TTL or RS-485 data bus.

Designed with the intention of being integrated directly inside of the object to be tracked, OS3DM is just 16 × 10 × 3.5mm. Additionally, its support of RS-485 allows for the possibility of utilizing multiple trackers simultaneously over a single data bus.

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 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.
