Each sensor measures a 3-axis signal in the cartesian reference x,y,z. The easiest way to do it is to choose the coordinate system of accelerometer as your reference coordinate system. So the first task (before integrating), is to convert the angular rates from the sensor-body frame to angular rates in the global frame. Rotation is positive in the counter-clockwise direction; that is, an observer looking from some positive location on the x, y or z axis at a device positioned on the origin would report positive rotation if the device appeared to be rotating counter clockwise. If it hasn't yet or is reset, we want to set the origin to the current gyroscope value. Some gyros come in single and dual axis varieties, but the triple axis gyro in a single chip is becoming smaller, less expensive, and more popular.
