2018年11月19日2時7分,我國在西昌衛星發射中心用長征三號乙運載火箭(及遠征一號上面級),以“一箭雙星”方式成功發射第四十二、四十三顆北斗導航衛星,這兩顆衛星屬于中圓地球軌道衛星,是我國北斗三號系統第十八、十九顆組網衛星。北斗三號向“一帶一路”國家和地區提供基本導航服務,邁出從國內走向國際、從區域走向全球“三步走”戰略的“關鍵一步”。
北斗之路,來之不易。從奮起追趕到并跑超越,中國北斗人在短短20余年里實現了衛星導航領域的“驚人飛躍"。北斗之光,惠及全球。從“中國奇跡”到“中國分享”,快速發展的中國北斗工程,為世界上渴望科技改善生活的人們帶來巨大機遇。
China has successfully sentry win BDS satellites into space?by a Long March- 3B launch vehicle(with an Expedition-1 upper stage)from the Xichang Satellite Launch?Center at 02:07 a.m. on November19th, 2018. The twins, both MediumEarth Orbit (MEO) satellites, are?the 42nd and 43rd of the Bei?Dou?Navigation Satellite System (BDS), and?the 18th and 19th of the BDS- -3 family.BDS-3 is designed to provide basicnavigation services for countries and?regions participating the Belt and RoadInitiative, which will be a "key step" forBDS- 3 in pursuing the "three- -step"strategy that aims for an increase from domestic?to international presence, and?from regional to global coverage.
China' s achievements in BDShave certainly not come easily.Twenty-odd years ago, China was?still exerting itself to catch up with the?best, while today, twenty- odd years?down the line, China is running neck?and neck with the best. Without the devotion?of our Chinese BDS people,China wouldn't' have made such a"striking leap-forward" in satellite navigation?within such a short timespan. By delivering services, BDS will benefit?people all over the world. From"Chinese miracle" to Chinese sharing",China's BDS project has achieved rapid?progress, opening up a world of opportunities?for people all over the world?who are eager to ameliorate their?livelihood through technologies.
