В работе предложена концепция управляемого предапертурного зеркала для быстрого перенаведения широкоугольного телескопа с полем зрения 3.75 ◦ и апертурой 30 см для космической системы обнаружения декаметровых астероидов (проект СОДА). Область наведения составляет 50 ◦ × 120 ◦ , время перенаведения между соседними площадками не более 3 с. Рассмотрены ближайшие российские и зарубежные аналоги, даны рекомендации по использованию управляемого зеркала в проекте СОДА. We propose a conceptual design of a controlled pre-aperture mirror for the fast repositioning of a wide field telescope with a field of view of 3.75 ◦ and an aperture of 30 cm for a space system to detect decameter sized asteroids (the SODA project). The pointing area is 50 ◦ × 120 ◦ and the repointing time between the adjacent fields is less than 3 seconds. Similar systems, equipped with a pre-aperture mirror, from different Russian and foreign projects have been considered, as well as recommendations on the use of a controlled mirror in the SODA project.
