    NameScopeTechnical featuresDomestic and foreign development
    Horizontal installationNormally, the diameter does not exceed 1.5 mBy quantitatively controlling and adjusting the relative position between the optical component and the structure, the RMS change of the optical component is no more than 0.02λDomestic remote sensor horizontal installation and adjustment technology is already very mature, and some technologies can reach the world's advanced level
    Vertical installationUsed for large-diameter and ultra-large-diameter remote sensors, it has been successfully applied to 6.5-meter aperture remote sensors abroadThe lens is adjusted vertically, and error removal technology is mainly used to remove gravity error, with an accuracy of up to 10%European and American countries have conducted research earlier and have already applied it in the development of multiple cameras such as GEOEYE and Kepler. The Beijing Institute of Space Mechanics and Electronics has established a vertical assembly production line and has successfully applied it to the development of remote sensors with excellent on-orbit performance
