ISatellite yefowuni yoKhetho lweMathiriyeli yeRadio: Ukulinganisa ukusebenza kunye nokuqina

Iirediyo zeefowuni zesathelayithi zizixhobo ezibalulekileyo zonxibelelwano lwangaphandle kunye nosasazo olungxamisekileyo. Ukhetho lwezinto eziphathekayo luchaphazela ngokuthe ngqo ukuthembeka kwabo, ukuqina, kunye namava omsebenzisi. Kwiindawo eziphakamileyo (ezifana nokuphakama okuphezulu, imimandla ye-polar, okanye iisayithi zeentlekele), iirediyo zeefowuni zesathelayithi kufuneka zimelane nemingeni efana nokutshintsha kweqondo lobushushu ngequbuliso, ukuguquka kokufuma, ukothuka, kunye nokugqwala. Ke ngoko, ukhetho lwemathiriyeli kufuneka lulungelelanise ukusebenza, ukhuseleko kunye neemfuno ezilula.

Izingxobo zenziwa ngeeplastikhi zobunjineli eziphezulu-ezifana nepolycarbonate (PC)) okanye i-magnesium{1}}i-aluminiyam alloy. I-Polycarbonate inika impembelelo egqwesileyo kunye nokuchasana kwemozulu, ukuxhathisa ngokufanelekileyo ukuhla kunye nokuthotywa kwe-UV, ngelixa ihlala ilula kwaye ifanelekile kwizixhobo eziphathekayo. I-Magnesium-i-aluminiyam ialloy, kwelinye icala, inika amandla amakhulu olwakhiwo kunye nokutshatyalaliswa kobushushu, iyenze ilungele izixhobo zobuchwephesha ezifuna ukomelela okukhulu. Nangona kunjalo, ibiza kakhulu kwaye inokunyusa ubunzima besixhobo.

Ukukhuselwa kweebhodi zesekethe zangaphakathi kuxhomekeke kwi-anti{0}}i-corrosion coatings kunye ne-antioxidant materials. Iirediyo zefowuni zesathelayithi zihlala zisebenza kwindawo -ezinomswakama ophezulu, ngoko ke iibhodi zesekethe zifuna ukugquma okusesikweni ({3}}ukungenwa kokufuma, ukuxhathisa ityuwa{4}}iyaxhathisa, kunye{5}}nokumelana nokungunda) ukukhusela izinto zombane. Ngaphaya koko, iziqhagamshelo eziphambili zihlala zifakwe ngegolide okanye i-nickel ukuphucula i-conductivity kunye nokumelana ne-oxidation.

Iziboniso zihlala zenziwe ngeglasi yeCorning Gorilla okanye ifilimu yepolyimide yokuphucula umkrwelo kunye nokumelana nokuwa. Eminye-imifuziselo ephezulu isebenzisa iteknoloji yesikrini ebhetyebhetye ukunciphisa umngcipheko wokwaphuka kwesikrini.

Izinto ze-antenna zichaphazela ngokuthe ngqo umgangatho wokufumana umqondiso. Izinto eziqhelekileyo zokusebenza eziphezulu-zibandakanya ubhedu-ngocingo lwe-aluminiyam olugqunyiweyo (olulungelelanisa ukuhanjiswa kunye nokukhanya) okanye i-eriyali zentsimbi engatyiwayo, eyokugqibela ikwazi ukumelana nomhlwa{3}}kummandla ogqithisileyo.

Isishwankathelo, ukukhethwa kwezinto eziphathekayo kwii-radio zefowuni ze-satellite kufuna ukulinganisela phakathi kwamandla, ukukhanya, ukukhuselwa, kunye neendleko zokuqinisekisa ukusebenza okuzinzileyo nokuthembekileyo kwiindawo ezinzima.
