Key Properties of Information Stability of an Automated Flight Control System for Spacecraft

The level of detail in the characteristics of an automated flight control system for spacecraft, which constitute the integrated property of information stability and therefore determine the system quality, has to be limited to the main properties. This is due to the fact that if the system is specified in great detail, the number of properties will run into hundreds. It will make the task of assessing the information stability indicator difficult to achieve, and important practical results will not be obtained. The main properties of the information stability of an automated control system are defined in the process of hierarchical decomposition of the integrated property. The first level includes three key properties of the automated flight control system for spacecraft: operating-technical level, restorability of the output data preparation process, and information security. The decomposition of the key properties of information stability is performed. The authors present the indicators that allow quantitative estimation of the degree to which the required indicators of the above-mentioned characteristics and the integrated property of information stability of the automated flight control system are achieved.
