2.6 Gibabit\/Saniye H\u0131zda Veri Aktar\u0131m\u0131 Sa\u011fland\u0131<\/b><\/p>\n

Avrupa Uzay Ajan\u0131 (ESA)<\/strong>, Airbus taraf\u0131ndan geli\u015ftirilen bir lazer terminalinin, D\u00fcnya\u2019dan yakla\u015f\u0131k 36.000 kilometre y\u00fcksekte bulunan Alphasat TDP 1 uydusuna ba\u015far\u0131yla kilitlendi\u011fini duyurdu. Jeostatik y\u00f6r\u00fcngede (GEO) konumlanan bu uyduyla kurulan ba\u011flant\u0131, birka\u00e7 dakika boyunca kesintisiz \u015fekilde 2.6 gigabit\/saniye h\u0131z\u0131nda veri aktar\u0131m\u0131 sa\u011flad\u0131<\/strong> ve bu s\u00fcre boyunca tek bir veri paketi dahi kaybedilmedi. ESA\u2019ya g\u00f6re bu h\u0131z, y\u00fcksek \u00e7\u00f6z\u00fcn\u00fcrl\u00fckl\u00fc bir uzun metrajl\u0131 filmi dakikalar yerine saniyeler i\u00e7inde aktarabilecek kapasiteye i\u015faret ediyor.<\/p>\n

Lazer ileti\u015fimde en b\u00fcy\u00fck sorunlardan biri, \u0131\u015f\u0131n\u0131n hedefi tam isabetle bulmas\u0131n\u0131 sa\u011flamak. Radyo dalgalar\u0131 gibi geni\u015f bir \u201ca\u011f\u201d olu\u015fturmayan lazerler, atmosferdeki dalgalanmalardan ve platformdaki titre\u015fimlerden kolayca etkileniyor. Airbus<\/strong> yetkilileri, bu mesafede hareketli hedefler aras\u0131nda lazer ba\u011flant\u0131s\u0131 kurman\u0131n son derece hassas y\u00f6nlendirme ve s\u00fcrekli d\u00fczeltme gerektirdi\u011fini vurguluyor. U\u00e7ak ile jeostatik uydu aras\u0131nda kurulan bu ba\u011flant\u0131, \u00f6zellikle hareket h\u00e2lindeki platformlar i\u00e7in dijital \u201c\u00f6l\u00fc b\u00f6lgelerin\u201d sonunu getirebilecek bir geli\u015fme olarak de\u011ferlendiriliyor. Uzun menzilli u\u00e7u\u015flar, okyanus ortas\u0131ndaki ara\u015ft\u0131rma gemileri ya da \u0131ss\u0131z \u00e7\u00f6llerden ge\u00e7en ara\u00e7lar i\u00e7in<\/strong> kesintisiz, gigabit seviyesinde internet art\u0131k daha ger\u00e7ek\u00e7i bir ihtimal.<\/p>\n

Bu arada Avrupa\u2019n\u0131n bu hamlesinden yaln\u0131zca birka\u00e7 g\u00fcn sonra \u00c7in\u2019den de benzer bir a\u00e7\u0131klama geldi<\/strong>. \u00c7in Optoelektronik Enstit\u00fcs\u00fc<\/strong>, hafta ba\u015f\u0131nda yapt\u0131\u011f\u0131 duyuruda 40.000 kilometrelik bir mesafede 1 Gbps h\u0131z\u0131nda lazer ba\u011flant\u0131s\u0131 kurduklar\u0131n\u0131 a\u00e7\u0131klad\u0131. H\u0131z ESA\u2019n\u0131n gerisinde kalsa da mesafe daha uzundu<\/strong> ve ba\u011flant\u0131 \u00fc\u00e7 saat boyunca s\u00fcrd\u00fcr\u00fcld\u00fc. \u00c7inli ekip, 1.8 metrelik bir yer istasyonu \u00fczerinden, y\u00fcksek mertebeli uyarlamal\u0131 optik sistem kullanarak atmosferik t\u00fcrb\u00fclans\u0131n neden oldu\u011fu sinyal bozulmalar\u0131n\u0131 ger\u00e7ek zamanl\u0131 olarak d\u00fczeltti. Uydu ile yer istasyonu aras\u0131ndaki kilitlenme ise yaln\u0131zca d\u00f6rt saniyede ger\u00e7ekle\u015fti.<\/p>\n

Y\u00fcksek y\u00f6r\u00fcngelerde (GEO) mesafe rekorlar\u0131 k\u0131r\u0131l\u0131rken, al\u00e7ak D\u00fcnya y\u00f6r\u00fcngesinde (LEO) ise h\u0131z yar\u0131\u015f\u0131n\u0131n daha da sertle\u015fti\u011fi g\u00f6r\u00fcl\u00fcyor. <\/strong>\u00c7in, Ocak ay\u0131nda LEO\u2019da 120 Gbps\u2019lik lazer ba\u011flant\u0131 h\u0131z\u0131na ula\u015ft\u0131\u011f\u0131n\u0131 duyurarak \u00f6nceki rekorunu ikiye katlad\u0131. \u00d6te yandan SpaceX<\/strong>, \u00fc\u00e7\u00fcnc\u00fc nesil Starlink uydular\u0131n\u0131 devreye almaya haz\u0131rlan\u0131yor.

E\u011fer bu teknolojiler olgunla\u015fmaya devam ederse, yaln\u0131zca D\u00fcnya \u00fczerindeki en \u00fccra noktalar de\u011fil, gelecekte Ay ve \u00f6tesindeki g\u00f6revler de kesintisiz y\u00fcksek h\u0131zl\u0131 veri ak\u0131\u015f\u0131na sahip olabilir.<\/strong><\/p>\n\n
