The correction mirror is installed in a biaxial suspension, which ensures its rotation for precise guiding. A diagonal mirror is flat, elliptical in shape. Its purpose is to move the focal plane to an area convenient for the location of detectors. Four detectors are installed on a turntable, <\/span>with the help of which the corresponding detector is installed. This platform has the ability to move along the optical axis within \u00b11.5mm for focusing.<\/span><\/p>\nThe diagonal mirror is placed in a biaxial suspension with piezo actuators for precise guiding. The telescope has a built-in star sensor for offset guiding. The peripheral part of a telescope’s field of view in which reference stars are selected for guiding, <\/span>is constructed using a small diagonal mirror located at a distance of 160 mm from the focal surface.<\/span><\/p>\nThe guidance sensor is equipped with a movement mechanism that allows it to be aimed at the selected reference star.<\/span><\/p>\n\nTwo options for placing the ASHOT telescope were studied. In one of these options, the telescope was installed in a rotating support device at the MIR orbital station. In the second version, the telescope was placed on a special spacecraft.<\/span>
\nIt operated in autonomous flight mode and periodically docked with the orbital station to carry out routine or repair work.<\/span><\/p>\n <\/p>\n
