Conclusion about fulfilling the SC performance task requirements, particularly requirements to linear ground resolution within panchromatic spectrum range, was proved on the basis of voluminous statistical data (more than 900 scannings). Exponential function was chosen as approximating expression of linear ground resolution. Appreciable best image plane travels were detected during normal SC operation.</p>Linear ground resolutiontelescope lensgray filterfocusingoptronic convertercharge-coupled devicepanchromatic rangematrixfineness of scanningЛинейное разрешение на местностиобъектив телескопанейтральный светофильтрфокусировкаоптико-электронный преобразовательприбор с зарядовой связьюпанхроматический диапазонматрицачисло строк накопления
