We need to set up GLONASS ground station in China, and China also needs to set up ground station in Russia. At present, it has entered the operation stage. We very much hope to start the installation in 2021, and we will go all out." < / P > < p > according to the news released on the official website of GLONASS navigation system, At present, there are 46 GLONASS ground stations in Russia, and another 7 ground stations are located abroad, including South America and Antarctica < p > on August 30, 2019, the sixth meeting of the China Russia satellite navigation major strategic cooperation project committee was held in Kazan, Russia. The two sides confirmed that the cooperation agreement between the government of the people's Republic of China and the government of the Russian Federation on the peaceful use of Beidou and GLONASS Global satellite navigation systems will soon enter into force. As an important government document for Sino Russian satellite navigation cooperation, the agreement promises that the two sides will exchange each other's satellite navigation system ground stations in their own territory < p > on June 23 last year, China successfully put the last beidou-3 networking satellite into the predetermined orbit with a long march-3b carrier rocket at Xichang Satellite Launch Center. So far, the deployment of beidou-3 global satellite navigation system constellation has been fully completed < p > at present, China has not yet established Beidou satellite stations in the world, only ground stations have been established in Pakistan and other countries. Last June, ran Chengqi, director of China's satellite navigation system management office and spokesman of Beidou system, told Pakistan United News Agency that China had established a Beidou navigation system ground station network in Pakistan < p > Xinhua News Agency previously said in the press release that because the Beidou system can not establish ground stations around the world like the US GPS. Therefore, in order to set up the data transmission channel of overseas satellites, the beidou-3 development team has conquered the constellation inter satellite link technology, adopted the integrated design of inter satellite and satellite ground transmission functions, and realized the link interworking between satellites and satellites, and between satellites and ground stations < p > at present, Russia is building a new generation GLONASS system. Nikolay jestoyedov, general manager of lesetnev information satellite system company, said at the general meeting of the Russian Academy of Sciences that within the framework of the plan approved in March, the constellation satellites of Russia's GLONASS navigation system will be increased to 30, and the satellite constellation system will adopt high elliptical orbit satellites, similar to China's Beidou system < p > at present, the GLONASS constellation consists of 27 satellites, but due to the particularity of the orbit structure of the system, only 24 satellites can operate < p > this article is the exclusive manuscript of observer.com and cannot be reproduced without authorization
