Development of a Module for Calculating a Simulated Scheme with Sparse Matrices

At present, there is a satellite surface electrification problem, caused by an impact of electrons and ions of cosmic plasma on a spacecraft outer covering. Due to such an impact the electrostatic discharge can occur, which can lead to a satellite damages or even to catastrophic hardware failures. To tackle the mentioned issue, the data on a current spreading over a spacecraft shell in a matrix representation are required. Thus, the main goal of the proposed graduation work is Development of a Module for Calculating a Simulated Scheme with Sparse Matrices. This module is created for applying in calculations on getting a pattern of a current distribution over a satellite outer covering. Within this paper an analysis of a spacecraft electrification issue was made as well as the ways of solving this problem and other related questions were discussed. Apart from that, the “Sattellite-MIEM” software and its mathematical background on current propagation was reviewed. Using acquired information from the review speed-drawbacks of a current approach to calculations were found. In order to provide a relevant speed the module based on the sequential implementation method and parallel technologies was created. At the end of the work comparative analysis of the implemented software solutions was held as well as the conclusions concerning rationality of their integration into the “Sattellite-MIEM” program on spacecraft electrification issue researches were made. Report volume on graduation work without appendix – 94 pages. The number of tables - 4, illustrations - 49, references - 27.
