Altogether 18 BDS satellites have been sent into space in 2018, making this year the most intensive launch of the BDS satellites.They improved their work efficiency by reforming the management process.The number of satellite staff at the launch center has been reduced by nearly half, and the testing time before launch has been shortened by nearly a third.In the CAST production base in Beijing, several BDS satellites are being manufactured at the same time.They try to improve intelligent manufacturing capability, and cut down production times.Construction of the BDS­3 system has accelerated. Once the BDS is fully completed, it will be the fourth global satellite navigation system after the US GPS system, Russi
