The purpose of the study is to develop methods and algorithms for high-precision of the SC attitude by measurements of the AS cluster. Methods of finding the attitude parameters of the SC, which use the aggregate data of direct measurements from the group of the same type of AS, provide more accurate estimates compared to the case of using one AS or orientation estimates obtained by the AS alone. The developed algorithmic software allows to effectively implement the stages of methods from the processing of source data to obtain a vector of estimates of attitude parameters. Research methods - methods of linear algebra, least squares method, optimally weighted least squares method, method based on singular decomposition. The obtained results: methods and algorithms for high-precision estimation of SC attitude using AS cluster measurements, methods for estimating relative SC attitude, methods for estimating SC angular velocity, and appropriate software for numerical modeling and verification of these methods Product Description popup.authors Volosov Victor V Gubarev Vyacheslav F Kuntsevich Vsevolod M Melnychuk Serhii V Salnikov Mykola Mykolaiovych Shevchenko Volodymyr M. popup.nrat_date 2022-03-09 Close
