Kina ka hapur nj\u00eb rrug\u00eb t\u00eb re n\u00eb komunikimet hap\u00ebsinore, duke vendosur lidhjen e par\u00eb dypal\u00ebshe me lazer n\u00eb nj\u00eb distanc\u00eb prej m\u00eb shum\u00eb se 400,000 kilometrash.<\/p>\n
Eksperimenti, i kryer midis nj\u00eb stacioni tok\u00ebsor dhe satelitit DRO-A, tregoi se sasi t\u00eb m\u00ebdha t\u00eb dh\u00ebnash mund t\u00eb transferohen me shpejt\u00ebsi shum\u00eb m\u00eb t\u00eb larta se sistemet tradicionale me mikroval\u00eb.<\/p>\n
Testi, i cili u b\u00eb pas m\u00eb shum\u00eb se nj\u00eb viti testimesh n\u00eb orbit\u00eb, \u00ebsht\u00eb nj\u00eb hap i r\u00ebnd\u00ebsish\u00ebm p\u00ebr Kin\u00ebn, nd\u00ebrsa teknologjia e komunikimit me lazer l\u00ebviz p\u00ebrtej aplikacioneve t\u00eb orbit\u00ebs s\u00eb ul\u00ebt t\u00eb Tok\u00ebs n\u00eb mjedisin Tok\u00eb-H\u00ebn\u00eb. Sistemi arriti 1.25 Mbps n\u00eb komunikimin Tok\u00eb-hap\u00ebsir\u00eb \u200b\u200bdhe 100 Mbps n\u00eb drejtimin e kund\u00ebrt.<\/p>\n
Dallimi shihet m\u00eb leht\u00eb kur flasim p\u00ebr imazhe dhe t\u00eb dh\u00ebna shkencore. Sipas Akademis\u00eb Kineze t\u00eb Shkencave, nj\u00eb imazh 8K i sip\u00ebrfaqes h\u00ebnore k\u00ebrkon rreth 4 deri n\u00eb 5 minuta p\u00ebr t\u2019u transmetuar n\u00ebp\u00ebrmjet nj\u00eb lidhjeje konvencionale me mikroval\u00eb 5 Mbps.<\/p>\n
Me nj\u00eb lidhje lazeri 100 Mbps, kjo koh\u00eb mund t\u00eb reduktohet n\u00eb rreth 12 sekonda. Ky \u00ebsht\u00eb nj\u00eb krahasim q\u00eb tregon aft\u00ebsit\u00eb e teknologjis\u00eb dhe nuk do t\u00eb thot\u00eb q\u00eb \u00e7do skedar 8K do t\u00eb transmetohet domosdoshm\u00ebrisht n\u00eb sakt\u00ebsisht 12 sekonda.<\/p>\n
Eksperimenti u krye si pjes\u00eb e programit t\u00eb eksplorimit DRO (Orbita e Distanc\u00ebs Retrograde) t\u00eb Kin\u00ebs. Sateliti DRO-A ishte i pajisur me nj\u00eb ngarkes\u00eb t\u00eb ve\u00e7ant\u00eb komunikimi me lazer, nd\u00ebrsa objektet tok\u00ebsore t\u00eb Akademis\u00eb Kineze t\u00eb Shkencave mor\u00ebn p\u00ebrsip\u00ebr transmetimin, pritjen dhe monitorimin e rrezes.<\/p>\n
Problemi i madh, megjithat\u00eb, ishte vet\u00eb distanca. N\u00eb m\u00eb shum\u00eb se 400,000 kilometra, edhe nj\u00eb devijim i vog\u00ebl n\u00eb drejtimin e rrezes mund t\u00eb shkaktoj\u00eb nj\u00eb gabim t\u00eb madh n\u00eb vendin ku do t\u00eb mb\u00ebrrij\u00eb ajo. Studiuesit duhej t\u00eb llogaritnin orbit\u00ebn e satelitit, shtremb\u00ebrimet e teleskopit, thyerjen atmosferike dhe koh\u00ebn q\u00eb i duhet lazerit p\u00ebr t\u00eb arritur objektivin e tij.<\/p>\n
Nj\u00eb problem i dyt\u00eb ishte dob\u00ebsimi i sinjalit . Pas nj\u00eb udh\u00ebtimi kaq t\u00eb gjat\u00eb, lazeri arrin Tok\u00ebn jasht\u00ebzakonisht i dob\u00ebt, n\u00eb nivelin e fotoneve t\u00eb vetme, nd\u00ebrsa sinjali duhet t\u00eb dallohet nga zhurma, drita e h\u00ebn\u00ebs dhe nd\u00ebrhyrje t\u00eb tjera. P\u00ebr k\u00ebt\u00eb, u p\u00ebrdor\u00ebn detektor\u00eb ultra t\u00eb ndjesh\u00ebm me foton t\u00eb vet\u00ebm dhe algoritme t\u00eb ve\u00e7anta p\u00ebrpunimi.<\/p>\n
Kina thot\u00eb se teknologjia e re mund t\u00eb luaj\u00eb nj\u00eb rol t\u00eb r\u00ebnd\u00ebsish\u00ebm n\u00eb misionet e ardhshme me pilot n\u00eb H\u00ebn\u00eb, stacionet k\u00ebrkimore h\u00ebnore dhe eksplorimin e hap\u00ebsir\u00ebs s\u00eb thell\u00eb, pasi misionet e ardhshme do t\u00eb gjenerojn\u00eb gjithnj\u00eb e m\u00eb shum\u00eb t\u00eb dh\u00ebna nga kamerat, instrumentet shkencore dhe eksperimentet.<\/p>\n
Pra, ajo q\u00eb aktualisht \u00ebsht\u00eb nj\u00eb eksperiment me lazer midis Tok\u00ebs dhe nj\u00eb sateliti mund t\u00eb b\u00ebhet baza p\u00ebr nj\u00eb brez t\u00eb ri t\u00eb komunikimeve hap\u00ebsinore me shpejt\u00ebsi t\u00eb lart\u00eb, nd\u00ebrsa njer\u00ebzimi kthehet n\u00eb H\u00ebn\u00eb dhe rrit pranin\u00eb e tij n\u00eb hap\u00ebsir\u00eb.<\/p>","protected":false},"excerpt":{"rendered":"
