About IMU Alignment error

Question

大家好，想咨询一下，IMU中的misaligment误差是如何区分Axis to axis与Axis to frame误差的？ 
 Hello,I would like to inquire about how the misalignment error in IMU distinguishes between Axis to axis and Axis to frame errors? Just like ADIS16446 datasheet show:

axis和axis是IMU内部敏感轴之间的，axis to frame是同一轴上传感器敏感轴和封装正交轴的角度偏差

可以，一个是自身的X和Y轴，一个是封装的X轴和实际敏感的X轴

我们的产品我们自己肯定在设计和测试是知道确切角度的，理论上是90度
