Home­grown PNT Sys­tem

Beijing Review - - This Week -

A high-pre­ci­sion na­tional com­pre­hen­sive po­si­tion­ing, nav­i­ga­tion and tim­ing (PNT) sys­tem based on the BeiDou Nav­i­ga­tion Satel­lite Sys­tem will be fin­ished by 2035, of­fi­cial sources said.

With the com­ple­tion of the sys­tem, China will im­prove its ca­pa­bil­ity in space and time in­for­ma­tion ser­vices, said Ran Chengqi, head of the Of­fice for the Man­age­ment of the BeiDou Nav­i­ga­tion Satel­lite Sys­tem. He made his re­marks dur­ing the Ninth China Satel­lite Nav­i­ga­tion Con­fer­ence held in Harbin, cap­i­tal of north­east China’s Hei­longjiang Prov­ince, on May 23-25.

Named af­ter the Chi­nese term for the Big Dip­per con­stel­la­tion, the BeiDou pro­ject was for­mally ini­ti­ated in 1994. It be­gan to serve China in 2000 and the Asia-Pa­cific re­gion at the end of 2012.

By around 2020, when the BeiDou sys­tem is due to go global, it will have more than 30 satel­lites.

The BeiDou sys­tem has been widely used in China for pub­lic se­cu­rity, trans­porta­tion, fish­ing, power sup­plies, forestry and dis­as­ter re­lief.

For ex­am­ple, 33,500 taxis and 21,000 buses in Bei­jing, and 40,000 fish­ing boats off the coun­try’s coast
