Checking the Required Accuracy of Measuring the State of Elastic Aerospace Vehicle Structure

The problem on providing the most accurate measuring information of an elastic aerospace vehicle (AV) state in real time is discussed. Such elastic AV can be large interplanetary spacecraft, a WIG-craft, or an airplane. For this purpose, it is proposed to place a sufficiently large number of inertial measuring modules along the AV body and perform verification and correction of their parameters during the flight. Such measuring modules should provide the necessary accuracy for a long time interplanetary flights. Micromechanical gyroscopes are used as the main measures. The results of digital modeling confirm the effectiveness of the proposed algorithms for verification of such important parameters of micro gyroscopes as the difference in the natural frequencies of primary and secondary oscillations and their Q-factor.
