Anyone want to help clarify this for me?

In robotics, it is properly called a yaw rate sensor. It's output is proportional to the velocity if angular rotation rather than the acceleration of other G sensors. This means that there is one less integration required to determine angle versus the double integration of an accelerometer required to give Cartesian coordinate position.

The reason that a YRS give velocity rather than acceleration is that is uses the Coriolis effect in its design.

Having said all this, you have enough info to Google away. If you have more questions after some investigation, fire away...
