A major project to monitor space has been launched in Beijing. The Meridian project will create a network of ground-based observatories. The network will use a line of observatories running north to south along the 120th east longitude. They will be located in Mohe, Beijing, Wuhan, Hainan and the Zhongshan Antarctic Station. In addition, an east to west line of observatories in Shanghai, Wuhan, Chengdu, Lasa will run along the 30th parallel of north latitude.
