Eye of the sky? Its main function is to use the unique natural karst depression site in Guizhou, the largest single aperture and the most sensitive radio telescope in the world. Eye of the sky consists of active reflector system, feed support system, measurement and control system, receiver and terminal, observation base, etc. The 10,000-ton platform is lowered to tens of tons by lifting and supporting the light lock net. It is difficult to meet this standard.
Dawodang, Jinke Village, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province, is located at 25 degrees north latitude and 106 degrees east longitude with a diameter of about 800 meters. It is about 85 kilometers northeast of Pingtang County and 45 kilometers southwest of Luodian County. It is generally located in the inclined zone of Guizhou Plateau and the transition zone to the hills of Guangxi.
Generally speaking, carbonate rocks are widely distributed in areas with high north and low south. The highest ridge is the elevation of 120 1m on the southeast mountain, and the lowest landmark of the depression is 84 1m, with the maximum relative height difference of 360m m. The terrain is undulating, the landform is similar and simple, and some mountains are steep, forming graffiti and cliffs. To sum up, considering the site selection, firstly, the landform is closest to the shape of the eye of the sky, and the development amount of the project is the smallest. Cover the antenna? Some people know that the bigger the aperture of the cover, the clearer the TV picture. For radio telescopes, the larger the aperture, the farther you can see. Radio astronomers all over the world are pursuing the construction of larger caliber? Pot cover? So as to improve that sensitivity of the radio telescope.
The karst geology here can ensure that rainwater seeps into the ground without being damaged and corroded. A large radio telescope needs a pure land. There are no towns and villages within 5km of Fiona Fang near this mountain, so the radio environment is very ideal.
Tianyan, independently developed by China, is the largest and most authoritative single-antenna radio telescope in the world. His design fully embodies China's scientific and technological ability, and can provide opportunities for development and breakthrough in many fields of basic research, such as exploring the deep structure and law direction of cosmic matter.
It is a scientific instrument aimed at 2 1 century, searching for dark matter and dark energy, including searching for extraterrestrial civilization. There is 99% mass and energy in the universe. We know its existence, but we don't know its characteristics. Eye of the Sky not only makes astronomers in China and even the whole world stare at it to solve the mystery of the origin of the universe. Sky Eye has a high-resolution microwave shape, based on the powerful function of Sky Eye. If there are aliens in the galaxy, their signals may be discovered by us. Since the birth of radio telescope, man has discovered about 2500 pulsars. If China Radio Telescope spends all its working time observing pulsars, it is expected that this number will double within one year.
