30 More Satellites to Make China’s Beidou GPS Centimeter-grade AccuratePosted: May 24, 2017 | |
Mil.huanqiu.com says in its report today that China will launch 6-8 satellites this year and more than 20 from 2018 to 2020 to make its Beidou navigation system centimeter-grade accurate.
In order to attain that goal, in addition to its efforts in space, China has completed the first step to intensify Beidou’s ground system with 150 base stations in its framework network and 1,200 base stations in its network of enhanced density.
Supported by the ground network China’s 15 satellites stably operating in the system can provide meter-grate navigation services covering 11 million square kilometers including entire China and centimeter-grade accurate navigation services for an area of 2.6 million square kilometers in China. There are five new satellites being fine-tuned on their orbits.
The nearly 30 new satellites to be launched in the coming 4 years will enable the system to have global coverage and China will complete the second step of the intensification of Beidou ground network by 2018 to enable Beidou to provide centimeter-grade accurate navigation services all over the world by 2020.
