The content and structure of tasks of diagnosing anomalies in spacecraft onboard systems operation

Abstract

The paper substantiates the possibility of the automated solution to the problems of detecting anomalies in the operation of onboard systems of a spacecraft, identifying and predicting deviations in the process of spacecraft operation based on changes in the values of telemetric parameters. The study provides insight into the content and structure of the tasks of diagnosing anomalies in the operation of onboard spacecraft systems, and analyzes the current state of the spacecraft flight control process. Within the research, we point out the drawbacks of the existing methods for monitoring telemetric information on the state of a spacecraft, and introduce possible solutions. We describe the principle of solving these problems of analyzing telemetric information using the wavelet transform method, and propose a method for automating the analysis process based on the special mathematical apparatus being developed. The paper gives a brief description of the mathematical transformations on which the proposed method for diagnosing anomalies in the operation of onboard systems is based.
