Ukusetshenziswa kwamadivayisi we-RF kubuchwepheshe besikhala
Amadivayisi we-Radio Frequency adlala indima ebalulekile kubuchwepheshe besikhala, ngoba asetshenziswa kabanzi emikhakheni efana nokuxhumana, ukuzulazula, kanye nokuzwa okukude. Ekuhlolweni kwesikhala nokusetshenziswa, iqhaza lamadivayisi we-Radio Frequency alinakufinyeleleka.
Okokuqala, amadivayisi we-RF adlala indima ebalulekile ekuxhumaneni kwesikhala. Ezinhlelweni zokuxhumana se-satellite, amadivaysi avamisile weRadio asetshenziselwa ukwamukela, andise, futhi adlulise amasiginali omsakazo, aqinisekise ukuhanjiswa kolwazi okuthembekile. Ukuxhumana kwe-satellite kudinga ukubekezelela izivivinyo ezedlulele zemvelo, futhi amadivaysi e-RF kumele abe nokuqina, ukumelana nemisebe, kanye nezimpawu eziphakeme kakhulu ukuqinisekisa ukuqina kanye nokwethenjwa kokuxhumana. Isibonelo, i-RF Amplifier ku-Satellite Payload inesibopho sokuthuthukisa amandla esiginali ukuqinisekisa ikhwalithi yokuxhumana igcinwa kumabanga amade; Ngasikhathi sinye, izihlungi ze-RF zisetshenziselwa ukukhetha amasiginali wemvamisa ethile ukuqinisekisa ukwamukelwa okunembile kanye nokudluliselwa kwezimpawu zokuxhumana.
Okwesibili, amadivayisi wemvamisa weRadio abuye adlale indima ebalulekile ekuzulazuleni kwesikhala. Izinhlelo zokuzulazula njenge-Global Positioning System (GPS) zisebenzisa amadivaysi avamisile weRadio ngokuthola iziginali, ukucubungula, kanye nokudlulisela, ukufeza isilinganiso esiqondile se-spacecraft isikhundla kanye nesivinini. Izihlungi ze-RF zisetshenziselwa ukukhetha amasiginali athunyelwe ama-satellite athile, kanti ama-RF amplifiers asetshenziselwa ukuthuthukisa amasiginali ukwenza ngcono ukunemba okuma. Endaweni yesikhala, izinhlelo zokuzulazula zidinga ukunemba okuphezulu nokuqina kwamadivayisi we-RF ukuqinisekisa ukunemba nokwethenjwa kokuzulazula kwe-satellite.
Ngaphezu kwalokho, amadivayisi we-Radio Frequency abuye adlale indima ebalulekile emkhathini ukuzwela okukude. Ukubukwa okukude kwe-satellite kusetshenziselwe ukubonwa komhlaba, ukuqapha imvelo, kanye nokuhlola izinsiza, futhi lokhu kulayishwa kwe-satellite kudinga amadivaysi e-radio radio ukucubungula amasiginali atholakele futhi adlulisele idatha emuva eziteshini zomhlaba. Ukusebenza kwamadivayisi wemvamisa yomsakazo kuzothinta ngokuqondile ukutholwa nokusebenza kokudluliswa kwedatha yedatha yokuzwa okukude, ngakho-ke izidingo eziphakeme zibekelwe phambili ngokuqina kwazo, ukuzwela, nekhono lokulwa nokulwa.
Sekukonke, ukusetshenziswa kwamadivayisi weRadio Frequency In Technology kufaka phakathi ukuxhumana, ukuzulazula, kanye nokuzwa okukude, ukudlala indima ebaluleke kakhulu ekusebenzeni okujwayelekile, ukuhanjiswa kwemininingwane, kanye nokutholwa kwedatha ye-spacecraft. Ngokuthuthuka okuqhubekayo kobuchwepheshe besikhala ngokuzayo, isidingo samadivaysi afudumele eRadio sizokhuphuka, futhi ukuqina kwabo kuzoqhubeka nokuthola okuphezulu ukuze kuvumelane nezimo ezinzima futhi ezinzima isikhala, ukubonwa komhlaba, ukuxhumana nokuzula, njll.
