The 60cm Laser-Ranging Station in the Sheshan campus of SHAO possess a laser-ranging instrument equipped with a 60cm telescope. Lasers, receiving terminals and laser-ranging control, and software/hardware components with a variety of functions have been installed to carry out all-weather observation of cooperative targets (satellites with reflectors) with cm accuracy within 40,000 km, and observation of non-cooperative targets (space debris) with decimeter accuracy at a maximal distance of 2,000 km. It is a major station in the international laser ranging network. The Sheshan observing station was the first in China to achieve laser ranging in the daytime, dual-wavelength laser ranging, and laser ranging for non-cooperative targets. For the first time in international circles, the station also realized satellite laser ranging with an ultra-high 10kHz repetition frequency, as well as daytime ranging of satellites in 40,000km synchronous orbits with kHz repetition rates. We have successively organized international joint observation missions for Shenzhou-4, Ocean-2 and the Beidou (“Compass”) series of satellites. We have undertaken important tasks such as the National Major Science & Technologies Basic Facilities Project (“The Chinese Continental Structure Monitoring Network”), large-aperture electro-optical telescope facilities, CAS Major Equipment and the “Twelve Five Years” space debris special project supported by the State Administration of Science, Technology and Industry for National Defense, laser-based time comparison, and so on.
