How does the MEMS gyro detect angular velocity? Also, note that the acceleration or linear velocity of the aircraft does not affect the measurement of the gyro. By detecting these small changes gyros help stabilize the flight of the aircraft. Instead they rotate a few degrees on each axis. Gyros are often used on objects that are not spinning very fast at all. 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. Is it clockwise around the axis, or is it counter-clockwise?Ī triple axis MEMS gyroscope, similar to the one pictured above ( ITG-3200), can measure rotation around three axes: x, y, and z. The spinning direction of the wheel is also important. It would have an angular velocity of 360 degrees per second. Imagine if the wheel spins once per second. The other two axes would not measure any rotation. If you attach the sensor to the wheel shown above, you can measure the angular velocity of the z axis of the gyro.
