China de­vel­ops edge in satel­lite tech­nol­ogy

China Daily European Weekly - - NEWS DI­GEST -

China has be­come a leader in the cut­ting-edge tech­nol­ogy of space-based, high-speed in­for­ma­tion trans­mis­sion thanks to an ad­vanced satel­lite, ac­cord­ing to the Na­tional Space Ad­min­is­tra­tion. The Shi­jian 13 com­mu­ni­ca­tion satel­lite has con­ducted the world’s first ex­per­i­ment on high­or­bit laser com­mu­ni­ca­tion, a tech­nol­ogy cru­cial to en­abling a space­craft to send, re­ceive and trans­mit a large quan­tity of data with ground sta­tions, the ad­min­is­tra­tion said in a state­ment on Jan 23. The ex­per­i­ment was one of the 11 tech­no­log­i­cal demon­stra­tion pro­grams made by Shi­jian 13, which is or­bit­ing nearly 40,000 kilo­me­ters above Earth, since it was lifted atop a Long March 3B car­rier rocket from Xichang Satel­lite Launch Cen­ter in Sichuan prov­ince in April. It proved that the satel­lite is ca­pa­ble of car­ry­ing out steady, high-speed and high-qual­ity trans­mis­sion of in­for­ma­tion with the ground.
