        Beijing TopView Technology Co., Ltd. is a professional institution which is able to provide the KeyHole full range of products and value-added services. With the powerful data management system, TopView is able to provide users with data query and production services accurately and quickly. 

        The launch time and distribution of KeyHole production can be roughly ascribed as:
        Between 1960 and 1972, 860,000 gray images are shot by KH-1 to KH-4 CORONA, KH-5 ARGON and KH-6 LANYARD. It covers all over the world, especially Eastern Europe and Asia.
        Between 1963 and 1980, about 50,000 gray images are shot by KH-7 GAMBIT and KH-9 HEXAGON. It covers most major cities and some important areas.At last 60s, a series of KH satellites is used for reconnaissance in United States, included KH-1, 4, and 5,6,7,9.
        KH-1 is the first generation of photo reconnaissance satellites, launched in October 1960, the working time is 3-28 days, the ground resolution is 3-7 meters; KH-4 is a detailed investigation of the first generation of photo reconnaissance satellites, launched in March 1962, working time is 3-5 days, the ground resolution is 2-3 meters; KH-5 which produced relatively low-resolution images compared to other spy satellites, was to provide imagery for mapmaking, launched in February 1963, working time is 20-28 days, the ground resolution is less than 3.6 meters; KH-6 is a high-resolution optical reconnaissance satellite, launched in July 1963, the working time is 4-10 days, the ground resolution is 0.6 m; KH-7 is a reconnaissance satellite which is the third-generation, launched in August 1966, the working time is 14-36 days, the ground resolution is 0.6 meters; KH-8 is the third-generation photo reconnaissance satellites, launched in July 1966, the working time is 9-90 days, the ground resolution is less than 0.6 m; KH-9 is the fourth generation of photo reconnaissance, launched in June 1971, the working time is 5-220 days, the ground resolution is 6 meters.
