Outline of Final Research Achievements |
The present study aimed at developing method to estimate a detailed shape and dynamics of solar sail without a huge calculation cost by fusing reduced order mathematical model and high reliablility orbit spatio-temporal missing mesurment data. This study has successfully develop the method to the following three problems: (1) Development of a fusing method of orbit measurement data and numerical calculation data, (2) Model reduction of large membrane space structure mathematical model and parallel computation, and (3)Consideration about a desgin method of predictable membrane space structure.
