China completes building the Beidou navigation system, its accuracy will be 10 Smolka Blinkova | 12.06.2020
China plans to bring this month into orbit last satellite navigation system Beidou, completing the project and creating analogue and competitor of the American GPS system (Navstar), the Russian GLONASS and
the European Galileo.
The idea to create Beidou appeared in China in 1990, when China began to tire of dependence on the US in the field of satellite navigation.
The Russian navigation system GLONASS, the recall was expanded to its full constellation in 1993, followed by its degradation because of the extremely small lifetime of spacecraft and their
a small reliability. Currently, the system is restored to normal mode, consisting of 27 satellites (according to 12.06.2020 Information-analytical center
the coordinate-time and navigation support), including 23 satellites are used for the intended purpose, one for maintenance, one at the flight test stage and two in the orbital reserve.
Also the European satellite navigation system Galileo is currently in its composition 22 of the satellite (necessary, recall of 30 satellites), two are in test mode,
two do not work, and the two finally withdrawn from the system for technical reasons. When it quit the EU now, the UK is planning the creation of an independent British
navigation system. Recall that Britain at the time made a substantial contribution (financial and technical) in the creation of Galileo.
And here in China is about to finish the creation of his system. During this time, China has come a long way — the first Beidou satellites were launched in 2000, in 2003, China tried to join Galileo, making
the project truly international and almost global, but not developed, and Chinese engineers focusing on their own project. At first only worked Beidou over China, then over
The Asia-Pacific region. In 2015 the Beidou has covered the whole world.
And recently, the 35-th satellite. It is expected that he will join the orbital segment of the Chinese navigation system in the current month. The total investment for the system is estimated at $10 billion.
According to Reuters, after the completion of the orbital segment, the accuracy of Beidou is 10 cm This is better than the American GPS (30 cm)
