    Estimation of zero offset components of modern gyroscopes using Allan dispersion
    (National Aviation University, 2024-06-14) Sharandak, Oleksiy Ruslanovych; Шарандак, Олексій Русланович
    Modern high-precision gyroscopes are essential components in various technical systems that require high stability and measurement accuracy. They are extensively utilized in contemporary aviation systems, space research, robotics, and other high-tech industries. The accuracy in determining the zero offset components is a critical measure of their efficiency and dictates their applicability in critical environments where navigation and orientation accuracy is paramount. Therefore, investigating these components and developing methods for their evaluation is a pressing scientific and technical challenge with significant practical potential for advancing control and navigation technologies. Scientific and technical issues related to the evaluation of the zero offset components of high-precision gyroscopes are addressed across a broad spectrum of applications, including navigation systems, aviation technologies, space research, and industrial applications. The current state of research in this field underscores the importance of gyroscope accuracy and reliability for modern technologies and scientific advancements. The primary foundational data for developing this topic includes an understanding of the principles of high-precision gyroscopes, methods for estimating their parameters, and knowledge of the Allan variance method and its application to gyroscope analysis. The necessity for this study lies in enhancing the accuracy and reliability of high-precision gyroscopes, which are pivotal components in numerous modern control and navigation systems. Evaluating the zero offset components will enable the identification and correction of deviations that occur under real operating conditions. Research on the evaluation of zero offset components has already yielded some practical results, highlighting an active interest in this issue and the potential for using the obtained data to improve technical systems. At the world level, there is a constant development of methods for evaluating and correcting the zero offset components of gyroscopes. This indicates the relevance of the topic and the need to constantly update knowledge in this area. The aim of this work is to evaluate the components of the high-precision gyroscopes bias using the Allan variance method, as well as to determine their impact on the accuracy and reliability of control systems. The feasibility study is to identify opportunities to apply the results obtained to improve the efficiency of technical systems and reduce the cost of their operation.
