Laser Unxibelelwano Payload

Intlawulo yoNxibelelwano lweLaser ibandakanya amazinga aphezulu okudluliswa kwedatha, inika unxibelelwano olukhawulezayo nolusebenzayo xa kuthelekiswa neenkqubo zeRF eziqhelekileyo, nto leyo eyenza kube yinto efanelekileyo kwizicelo ezinzulu zedatha ezifana ne-high-resolution satellite imaging kunye nonxibelelwano olunzulu lwendawo. Iimpawu zayo zokhuseleko ziyenza imelane nokukhawulelwa okanye ukuxinana, iqinisekisa ukuba idatha ebuthathaka ihlala ikhuselwe. Uyilo oludityanisiweyo lwenkqubo luvumela ukudityaniswa lula kwiziphekepheke ezisele zikho kunye neenkqubo zesathelayithi, ngelixa ukusetyenziswa kwayo kwamandla aphantsi konyusa impumelelo yobuthunywa. Ukongezelela, ukukwazi ukubonelela ngonxibelelwano oluphezulu lwe-bandwidth kumgama omde kwenza ukuba kube ngumtshintshi womdlalo wokuhlola indawo yexesha elizayo kunye nothungelwano lonxibelelwano lwehlabathi.

I-Laser Communication Payload yinkqubo ephucukileyo eyenzelwe ukubonelela ngesantya esiphezulu, esikhuselekileyo, kunye nokuhanjiswa kwedatha okude usebenzisa imiqadi yelaser. Lo mthwalo wokuhlawula uqukethe i-laser transmitters, abamkeli, kunye neemodyuli zonxibelelwano lwe-optical, ezisebenza kunye ukuseka ikhonkco elizinzileyo kunye nomthamo ophezulu wonxibelelwano lwesathelayithi, ukuhlola indawo, kunye nezicelo ezisekelwe emhlabeni. Inkqubo iphakamisa itekhnoloji yelaser ye-infrared ukuhambisa idatha ngesantya esiphezulu kakhulu xa kuthelekiswa neenkqubo zonxibelelwano zikanomathotholo zesiqhelo (RF), ezivumela ukuhanjiswa komthamo wedatha enkulu kunye nokulibaziseka okuncinci. Intlawulo yonxibelelwano lwelaser yenzelwe ukuphatha uthumelo olukhuseleke kakhulu, iqinisekisa imfezeko yedatha kunye nokuchasana nokungenelela. Ibonisa ukuchaneka okuphezulu kunye neenkqubo zokulandela umkhondo, ukuqinisekisa ukuba i-laser beam ihlala iqondiswe ngokuchanekileyo phakathi kweeyunithi zokudlulisa kunye nokwamkela, nakwiindawo eziguquguqukayo ezifana nokunyakaza kwesathelayithi. Yenzelwe imisebenzi yendawo, inokusebenza kumaqondo obushushu aphezulu kwaye imelane neemeko ezinzima zendawo, ibonelela ngonxibelelwano oluthembekileyo kwimigama emide.
