The accuracy of this technology directly affects the stability and safety of related applications, so it plays a vital role in improving navigation accuracy, steady-state control and attitude adjustment.

[0003] In the prior art, although the sensor itself can obtain high-precision data, users often face the challenge of not being able to intuitively understand the measurement data during use.
