You either need to start the device in a known initial global orientation and measure how much the orientation changes, or you need other devices to determine the "initial" or periodic global reference frame. Gyro Sensors. Their shape strongly affects the eigenfrequencies of the structure. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. The access needs to remain on to control the sensors and data streaming from MATLAB. So if the sensor is rotating with some rate, the data it's outputting will be in the frame of the rotating sensor, NOT with respect to the fixed global frame. By default, the filter names the sensors using the format 'sensorname_n', where sensorname is the name of the sensor, such as Accelerometer, and n is the index for additional sensors of the same type.
