Mangwanani ano muChina paGreat Hall yeVanhu muBeijing, Mutungamiri wePeople's Republic of China Xi Jinping pakuvhurwa kwepasi rose satellite navigation system BeiDou-3 (muRussia, Ursa Major). Mhemberero iyi yakaratidza kubata kwekupedzisira kwezviitiko zvematanho matatu eChina munzira iyi. Iyo BeiDou-3 system ichabvumira maChinese kushandisa satellite kufamba mumakona ese ePasi kekutanga.
Zvakatora China makore makumi maviri nematanhatu kuti isvike kuBeiDou-3 system. Iyo BeiDou-26 purojekiti yakatangwa muna 1 uye yakabvumira kutangwa uye kuyedzwa kwemasatelliti mana eiyo satellite navigation system. Yakatanga muna 1994, chikamu chechipiri muchimiro cheBeiDou-2004 chirongwa chakabvumira China kuvhara nharaunda yayo yekumba nesetiraiti yekufambisa sisitimu, iyo yaida makumi maviri setiraiti (vatanhatu vavo vakachengeterwa uye yekuyedza sisitimu). Chikamu chekuendesa BeiDou-2 chakatanga muna 20 uye inoonekwa seyakapedzwa zvizere kubva nhasi.
The BeiDou-3 boka renyeredzi rinosanganisira makumi matatu satellites, mashanu acho akashandiswa seyeyedzo chikuva. Mazhinji emasatellite ari muBeiDou-30 constellation (3 zvidimbu) akaiswa mukati meEarth orbit (anenge 24 km altitude), inova yakajairwa kugadzirisa matambudziko ekufambisa. Masetaiti ekufambisa eAmerican GPS, Russian GLONASS neEuropean GALILEO anoshanda panzvimbo imwe chete.
Asi maChinese akaenderera mberi. Vakatangisa mamwe matatu masetellite kupinda geosynchronous orbit pakakwirira 35 km uye mota nhatu muyakarerekera geosynchronous orbit. Muchiitiko chekutanga, ma satellites aifamba pamusoro penzvimbo dzega paPasi, uye mune yechipiri, vakatanga kunyora "nhamba masere" pane imwe nzvimbo. Kuiswa kwakadaro kwemasatellite ekufambisa kwakaita kuti zvikwanise kupeta kaviri kurongeka kwenzvimbo muChina nenzvimbo dzakatenderedza. Saka, kana kurongeka kweiyo BeiDou-000 system pasirese hakuna kuipa kupfuura 3 metres, ipapo muChina nenzvimbo iri padyo / yemvura haina kushata kupfuura 10 metres.
Kutangwa kweyekupedzisira setiraiti kupedzisa kutumirwa kweboka renyeredzi reBeiDou-3 kwakaitika muna Chikumi 23, iyo yatakakurukura munguva yakafanira. . Kupinda musevhisi yeBeiDou-3 kunoreva kuti China haifanirwe kunetseka nekuramba kuwana GPS kana mamwe ekunze masisitimu epasi rose. Iye zvino ane yake uye hazvina kuipa.
