Data collecting technique of strapdown inertial measuring unit

In the strapdown inertial measuring unit-123, the precise measurement of angular velocity and acceleration is the basis for mastering exactly the information of navigation and guidance. So it is necessary to have a high precision and little error system to collect and deal with data. To satify this requirement, the data collecting technique was described , which is a groupware of the Srtapdown Inertial Measuring Unit-123.
