China's new GPS tracking system is much more accurate than current US systems

Asia Times:

China is building a military-grade navigation system called BeiDou-3 that will have global coverage through more than 30 satellites, according to an academic speaking on the sidelines of the 19th National Congress of the Communist Party of China.

In 1995, China started to develop its first BeiDou Navigation Satellite System as an alternative to the Global Positioning System in use by the United States, Dr Wang Feixue, a professor at the College of Electronic Science and Engineering, National University of Defense Technology, said at a media briefing on Sunday evening.

“Our satellite program kicked off 20 years later than foreign countries’. We have not yet achieved full global coverage at the moment,” Wang said. “There is still a long way for us to go.”

As China only had the resources to launch six satellites two decades ago, its scientists could only use two satellites to track an object, he said. However, they faced a problem with “fast capture”, a key technology for navigation, he said.

“At that time, my team and I were interested in taking the challenge, and finally tackled the problem by using some new technologies,” he said. Based on their achievements, China now has BeiDou-2, which can connect to more than 10 satellites, and is developing BeiDou-3, he said.

“Even if our satellite system can achieve full global coverage by 2020, we should not slow down, as technology is improving every day,” he said. His team will continue to help equip the People’s Liberation Army with new technologies.

Previous media reports said BeiDou-3 would be able to achieve an accuracy “within millimeters”, 10 times as precise as GPS.

This could greatly improve the accuracy of their precision-guided munitions.  It shows theri commitment to war technology.
