I-Laser Communication Payload

I-Laser Communication Payload ihlanganisa amanani ayo aphezulu okudluliswa kwedatha, enikeza ukuxhumana okusheshayo nokuphumelelayo uma kuqhathaniswa nezinhlelo ze-RF ezivamile, okuyenza ibe ilungele izinhlelo zokusebenza ezidinga idatha ezifana nesithombe sesathelayithi enesinqumo esiphezulu nokuxhumana okujulile emkhathini. Izici zayo zokuphepha ziyenza imelane nokuphazanyiswa noma ukuminyana, iqinisekisa ukuthi idatha ebucayi ihlala ivikelekile. Idizayini ehlangene yesistimu ivumela ukuhlanganiswa okulula kumikhumbi-mkhathi ekhona nezinhlelo zesathelayithi, kuyilapho ukusetshenziswa kwayo kwamandla okuphansi kuthuthukisa ukusebenza kahle kwemishini. Ukwengeza, ikhono layo lokuhlinzeka ngokuxhumana komkhawulokudonsa ophezulu emabangeni amade kuyenza iguqule umdlalo wokuhlola indawo esikhathini esizayo kanye namanethiwekhi okuxhumana omhlaba.

I-Laser Communication Payload iwuhlelo oluyinkimbinkimbi olwakhelwe ukuhlinzeka ngokudluliswa kwedatha ngesivinini esikhulu, evikelekile, kanye nebanga elide kusetshenziswa imishayo ye-laser. Lo mthwalo okhokhelwayo uqukethe ama-laser transmitters, abamukeli, kanye namamojula okuxhumana okubona, asebenza ndawonye ukuze asungule isixhumanisi esizinzile nesinamandla amakhulu sokuxhumana ngesathelayithi, ukuhlola indawo, kanye nezinhlelo zokusebenza ezisekelwe phansi. Uhlelo lusebenzisa ubuchwepheshe be-laser ye-infrared ukudlulisa idatha ngesivinini esiphezulu kakhulu uma kuqhathaniswa nezinhlelo zokuxhumana zerediyo evamile (RF), okuvumela ukudluliswa kwamavolumu amakhulu wedatha ngokubambezeleka okuncane. Inkokhelo yokuxhumana nge-laser yakhelwe ukuphatha ukudluliselwa okuvikeleke kakhulu, iqinisekisa ubuqotho bedatha kanye nokumelana nokuvinjwa. Ihlanganisa ukunemba okuphezulu kokukhomba kanye nezinhlelo zokulandela umkhondo, iqinisekisa ukuthi i-laser beam ihlala iqondiswe ngokunembile phakathi kwamayunithi okudlulisa nawamukelayo, ngisho nasezindaweni eziguquguqukayo ezifana nokunyakaza kwesathelayithi. Idizayinelwe ohambweni lwasemkhathini, ingasebenza emazingeni okushisa aphakeme futhi imelane nezimo ezinzima zesikhala, inikeze ukuxhumana okuthembekile kumabanga amade.
