What you're learning today is good, but tomorrow you're going to need something else.
你今天在学的东西是好的，但明天你还会需要别的东西。
We need something else. Let's look at an example, and we will see how that leads us to the method.
我们需要来点别的，先看一个例子，然后通过这个例子，一起把那个方法推导出来。
Do you only need this? If you need something else, could you make a detailed list?
你只需要这个吗？如果还需要其他的可以列个明细出来吗？
For yaw, which is orthogonal to gravity, the accelerometers can't help you, so you need something else to correct your drifting yaw gyro.
对于偏航角度，由于偏航角和重力方向正交，无法用加速度计测量得到，因此还需要采用其他设备来校准测量偏航角度的陀螺仪的漂移值。
