Ngale ntsasa eTshayina kwiHolo eNkulu yaBantu eBeijing, uMongameli weRiphabhlikhi yabantu baseTshayina uXi Jinping ekuqalisweni kwenkqubo yokukhangela ngesathelayithi yehlabathi i-BeiDou-3 (ngesiRashiya, i-Ursa Major). Lo msitho uphawule ukubamba kokugqibela kwemisebenzi yaseTshayina yamanqanaba amathathu kule ndawo. Inkqubo ye-BeiDou-3 iya kuvumela amaTshayina ukuba asebenzise i-satellite navigation kuzo zonke iikona zomhlaba okokuqala.
Kwathatha i-China iminyaka eyi-3 ukuya kwi-BeiDou-26 inkqubo. Iprojekthi ye-BeiDou-1 yasungulwa kwi-1994 kwaye yavumela ukuqaliswa kunye nokuvavanywa kwee-satellites ezine kwinkqubo yokuhamba nge-satellite. Iqaliswe kwi-2004, isigaba sesibini ngendlela yeprojekthi ye-BeiDou-2 yavumela i-China ukuba igubungele ummandla wayo wasekhaya ngenkqubo yokuhamba ngesathelayithi, eyayifuna ii-satellites ze-20 (ezintandathu zazo ezigciniweyo kunye nokuvavanya inkqubo). Inqanaba lokuthunyelwa kwe-BeiDou-3 laqala ngo-2009 kwaye lithathwa njengeligqitywe ngokupheleleyo njenganamhlanje.
Iqela leenkwenkwezi le-BeiDou-3 libandakanya iisathelayithi ezingama-30, ezintlanu zazo zasetyenziswa njengeqonga lovavanyo. Uninzi lweesathelayithi zeBeiDou-3 constellation (iziqwenga ezingama-24) zibekwe kwi-medium-Earth orbit (malunga ne-20 km altitude), nto leyo eqhelekileyo ekusombululeni iingxaki zokuhamba. Iisathelayithi zokukhangela zeGPS yaseMelika, iGLONASS yaseRussia kunye neGALILEO yaseYurophu zisebenza kwindawo enye.
Kodwa amaTshayina aqhubela phambili. Bazise ezinye iisathelayithi ezintathu kwi-geosynchronous orbit kumphakamo oyi-35 km kunye nezithuthi ezintathu kwi-geosynchronous orbit. Kwimeko yokuqala, iisathelayithi zahamba phezu kwamanqaku ngamnye eMhlabeni, kwaye okwesibini, baqala ukubhala "umzobo wesibhozo" kwindawo ethile. Ukubekwa okunjalo kweesathelayithi zokuhamba kwenze ukuba kube lula ukuphinda kabini ukuchaneka kokumisa e-China nakwindawo engqongileyo. Ngoko ke, ukuba ukuchaneka kokubekwa kwenkqubo ye-BeiDou-000 emhlabeni jikelele akukho kubi ngaphezu kweemitha ezili-3, ngoko e-China nakwindawo ekufutshane / kwindawo yamanzi akukho kubi ngaphezu kweemitha ezi-10.
Ukuqaliswa kwesathelayithi yokugqibela ukugqibezela ukuthunyelwa kweqela leenkwenkwezi i-BeiDou-3 kwenzeka nge-23 kaJuni, esiye saxoxa ngayo ngexesha elifanelekileyo. . Ukungena kwinkonzo ye-BeiDou-3 kuthetha ukuba i-China ayinakukhathazeka malunga nokwala ukufikelela kwi-GPS okanye ezinye iinkqubo zokubeka amazwe ngamazwe. Ngoku uneyakhe kwaye akukho worse.
