Aerospace Instrument-Making Annotation << Back CONCEPTUAL MODEL OF THE SOFTWARE COMPLEX FOR ANALYSIS OF THE STATE OF THE ORBITAL GROUP OF SPACE VEHICLES G.A. Zubkov, I.G. Ivanov, K.A. Okhlopkov, N.M. Golovin, M.K. Bondareva The work is devoted to the development of a model of a software package for analyzing the state of an orbital constellation of spacecraft, which is based on an object-oriented approach. The need to create software is due to the lack of a systematic approach to assessing the complex state of the orbital constellation of spacecraft. The proposed software package includes the following modules: assessing the life cycle of the spacecraft, assessing the technical condition along the planes of the orbital constellation, assessing the failures of the orbital constellation, assessing flight tests, modeling onboard equipment malfunctions with their effect on the performance of tasks for the intended purpose, predicting the technical state , the issuance of proposals for replenishing the orbital group, as well as a control unit for the implementation of tasks for the intended purpose. The use of this software package will make it possible to carry out a comprehensive analysis of the state of the orbital constellation, which will make it possible to take timely measures to plan the use of the orbital constellation for its intended purpose. Keywords: modeling, spacecraft, orbital constellation, forecasting, system analysis. DOI: 10.25791/aviakosmos.7.2021.1231 Pp. 36-41.
