Automatic rotary device for verification of the accuracy characteristics of strapdown inertial navigation system

The report focuses on the experience of creating an automatic biaxial rotary test bench for verification of the accuracy characteristics of strapdown inertial navigation systems (SINS). Attention is given to construction solutions adopted in the design process and to the methods of controlling the parameters of SINS. Features of the tracking drive performed on the basis of a stepping motor are considered, the associated controlling algorithms are studied. A mathematical model of the rotary bench is formed, the results of the prototype testing are presented.
