Математические методы, используемые для оценки точности положения и формы крупногабаритного рефлектора космического аппарата

The article considers some mathematical methods used to assess the position accuracy as well as the form accuracy of a reflecting surface of a large-sized spacecraft reflector. The basic points and examples of each method are given. The following mathematical methods: using a kinematic scheme boom-reflector; the method for selecting the control points of the reflecting surface; the method of determining the RMS of reflecting surface; the method of determining the best fit paraboloid are developed by the author of the article.
