What is the opening time of the origin of the earth

Opening hours of the geodetic origin: 9: ~ 18:

Introduction of the geodetic origin scenic spots:

The Chinese people * * * and the geodetic origin are located in Shijisi Village, Yongle Town, Jingyang County, Xianyang City.

Geodetic origin is also called geodetic datum point, which is the starting point for calculating geodetic coordinates in the national horizontal control network. At the beginning of the founding of the People's Republic of China, the geodetic coordinate system used in China was measured from the former Soviet Union, and its coordinate origin was the Bolkov Observatory of the former Soviet Union. This situation is extremely disproportionate to China's construction and development. To this end, the relevant state departments decided to establish an independent geodetic coordinate system in China. Since 1975, we have organized manpower, collected and analyzed a large amount of data, and made on-the-spot investigation and comprehensive analysis of topography, geology, geotectonics, astronomy, gravity and geodesy in Zhengzhou, Wuhan, Xi 'an and Lanzhou according to the requirements of the origin, and finally determined the origin of China's earth in Shijisi Village, Yongle Town, Jingyang County.

The whole facility of Geodetic Origin consists of four parts: central sign, instrument platform, main building and projection platform. The three-dimensional building more than 25 meters above the ground has seven floors, and the top floor is the observation room, with an instrument table; The top of the building is an integral semi-circular roof made of glass fiber reinforced plastic, which can be opened electronically to observe celestial bodies; The central sign is buried in the center of the basement of the theme building. Shortly after its completion, the national basic gravity point and astronomical basic point were added and measured at the origin of the earth.
