2065438+September 2006 Where did the 500m spherical surface finish and start?

2065438+In September 2006, a 500-meter spherical radio telescope was built and started in Pingtang, Guizhou.

The 500-meter spherical radio telescope is located in Dawodang, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. This project is a major national science and technology infrastructure. The "Eye of the Sky" project consists of an active reflector system, a feed support system, a measurement and control system, a receiver, a terminal and an observation base.

The 500-meter spherical radio telescope took 22 years to build and was put into use on September 25th, 2006. It is the largest single-aperture and most sensitive radio telescope in the world, which is led by the National Astronomical Observatory of Chinese Academy of Sciences and has independent intellectual property rights in China. The comprehensive performance is ten times that of the famous radio telescope Arecibo.

Extended data

The 500-meter spherical radio telescope has important application value in the country's major demand. Extending China's space TT&C capability from geosynchronous orbit to the outer edge of the solar system will increase the downlink rate of deep space communication data by 100 times.

The measurement accuracy of pulsar arrival time is improved from 120 nanoseconds to 30 nanoseconds, making it the most accurate pulsar timing array in the world and making pulsar clocks for the prospective research of autonomous navigation. Carry out high-resolution microwave patrol, diagnose and identify weak spatial signals with a resolution of 1Hz, and serve national security as a passive strategic radar.

As a "meridian project", the receiving system of incoherent scattering radar provides high resolution and high efficiency ground observation; Tracking and detecting coronal mass ejections serve the space weather forecast.
