China is about to launch a positioning satellite

North Dau-3 satellites could be put into orbit later this month. According to developers, the latest North Dau system has 10 times the accuracy of US GPS.

According to the South China Morning Post, a Chinese aerospace website, the country has its most recent North Dau-3 launcher , satellite navigation and navigation later this month. Manufacturers claim the technology that satellites use "exactly millimeters".

The 91fly.cn website said the two North Dau-3 satellites are expected to be launched on September 29. Evidence of the launch of the satellite is also released by PLA Daily on September 11. According to the official Chinese military channel, a surveillance ship left the military port in Jiangsu Province last Sunday to monitor satellites.

91fly.cn had accurately predicted the launch date of satellites. According to the site, from a launch site in Sichuan province, two North Dau-3 satellites will be brought into the orbit by CZ-3B Long March .

Yang Yuanxi, vice president of satellite systems design North Korea, stated in advance that the new satellites are 10 times more accurate than the models available, because North Dau-3 has an atomic clock. can reduce errors to only a few millimeters.

According to Li Min, a researcher at Wuhan University GNSS Center, North Dau-3 is the most advanced navigation and navigation satellite in the world. However, he also warned that only the effectiveness of Bac Dau-3 could be assessed after a period of use."In fact, accuracy is not only affected by atomic clocks but also by the magnitude and complexity of the space."

The North Dau-3 operation is hardly noticeable for civilian users. Only military or government-approved organizations have access to this ultra-high-precision positioning service for special tasks.

The two satellites were originally scheduled to launch in late July, but the event was postponed after two successive failures of the Long March missile in missions carrying other satellites.

The most recent launch of the heavy-duty CZ-5 rocket has destroyed China's largest satellite and forced authorities to postpone the next launches.

The North Dau-3 is a new generation satellite developed by China , providing global positioning and navigation services. China started the Bac Dau program, also known as Compass, in the early 1990s to compete with the GPS global positioning system developed by the US.
