Многоуровневое системотехническое обеспечение функциональной работоспособности систем управления движением и навигации малогабаритного космического аппарата

Abstract

Here we present one of the possible solutions to the scientific and applied problem of ensuring the functional stability of the small-sized spacecraft stabilization and orientation systems. Our research resulted in unification of the proposed models and methods of diagnostics, as well as presentation of a scheme for development of the algorithmic support for diagnostics of the functional condition of the movement and navigation control system (MNCS). The proposed approach organizes the development process and ensures a reduction of labor costs and quality improvement, i.e. an increase of the efficiency of the diagnostic software engineering. Application of the modified FDM developed to restore the functional state of a dynamic object provided opportunities to unify the proposed models and to adapt the known methods, as well as to form a scheme for development an algorithmic support for the situational restore of the functional condition of the MNCS. The proposed scheme systematizes knowledge, tools and specific experience in the development of algorithms obtained from the studies. The use of such a scheme in real projects can improve the quality of functioning of the recovery modules and save time and resources for their development.
