China’s BeiDou satellite navigation system is going to cover the whole world, starting with the two BeiDou-3 satellites launched yesterday.

The China-developed system has been providing navigation services in the Asia-Pacific region since 2012, and the new third-generation system will provide even better service. It uses the widely-adapted B1C signals, making it easier to communicate with other countries’ satellites.
“We will start evaluating the satellites once they get into their target orbits,” said Yang Changfeng, chief designer of the system. “It will be available to the public.”
China’s Sat-Nav Progress
China is the third country in the world to own a self-developed sat-nav system, after GPS in the US and GLONASS in Russia.
The country intends to launch an additional 18 BeiDou-3 satellites next year, which will cover all the Belt and Road countries.

The finished system will contain more than 30 satellites, and cover the whole world by 2020.
There are currently three systems that can provide global coverage. In addition to the US and Russian ones, there’s Galileo, made by the European Space Agency.
The rocket used in the launch was the Long March-3B, which was launched from Xichang Satellite Launch Center in southwest China’s Sichuan Province.
“The success rate of BeiDou satellite launches remains 100 percent,” said Lin Yunan, head of HR in the launch center.
