Amasathelayithi

Amasathelayithi ayizinto zokwenziwa ezibekwe ku-orbit ezizungeze izindikimba zasezulwini ukuze kuqoqwe idatha, kunikwe amandla ukuxhumana, futhi kusekele ucwaningo lwesayensi. Badlala indima ebalulekile ekuzulazuleni, ekubikezelweni kwesimo sezulu, ekusebenzeni kwezempi, nasekuhloleni indawo, okuthinta kakhulu ubuchwepheshe besimanje nempilo yansuku zonke.

Yiziphi Izinhlobo Ezihlukene Zesathelayithi Nemisebenzi Yazo?

Amasathelayithi ahlukaniswa ngokusekelwe emsebenzini wawo kanye nohlobo lokuzungeza asebenza kuwo. Izinhlobo eziyinhloko zamasathelayithi zihlanganisa amasathelayithi okuxhumana, amasathelayithi okubuka umhlaba, amasathelayithi okuzulazula, amasathelayithi esayensi, namasathelayithi ezempi. Ngayinye yalezi isebenzela injongo ethile futhi inikela ezimbonini ezihlukahlukene.Amasathelayithi okuxhumana asetshenziselwa ukudlulisa amasignali kamabonakude, umsakazo, ne-inthanethi emhlabeni wonke. Benza ukuxhumana okungenazihibe emhlabeni wonke, baqinisekise ukuthi abantu abasezindaweni ezikude bayafinyelela ezinsizeni zokuxhuma ezibalulekile. Lawa masathelayithi amiswe ku-geostationary orbit, okuwavumela ukuthi amboze indawo enkulu ngaphandle kokubekwa kabusha njalo.Amasathelayithi okubuka umhlaba, aziwa nangokuthi ama-remote sensing satellite, aqapha izinguquko zemvelo, alandelele izinhlekelele zemvelo, futhi asekele ukuphathwa kwezolimo nezinsiza. Zinikeza izithombe ezinokulungiswa okuphezulu ezisiza ohulumeni, abacwaningi, namabhizinisi ukuba benze izinqumo ezinolwazi mayelana nokushintsha kwesimo sezulu, ukugawulwa kwamahlathi, nokuhlela amadolobha.Amasathelayithi okuzulazula, njengalawo aku-Global Positioning System (GPS), anika amandla ukulandelela indawo okunembile kwezokuthutha, ezempi, nokusetshenziswa komuntu siqu. Lawa masathelayithi adlulisa amasignali ngokuqhubekayo avumela amadivayisi asemhlabeni ukuthi anqume indawo yawo enembile, athuthukisa ukuzulazula kwezinkampani zezindiza, izinkampani zemikhumbi, kanye nabasebenzisi abangabodwana.Amasathelayithi esayensi aqaliswa ukutadisha indawo, amaplanethi, nezinye izindikimba zasezulwini. Lokhu kuhlanganisa izibonakude ezifana ne-Hubble Space Telescope, ehlinzeka ngezithombe ezimangalisayo zendawo ejulile, esiza ososayensi baqonde umsuka wendawo yonke kanye nezakhiwo.Amasathelayithi ezempi asekela imizamo yezokuphepha kazwelonke ngokuqoqa ubuhlakani, ukulandelela ukuqhuma kwemicibisholo, nokugada. Lawa masathelayithi ahlukaniswe kakhulu adlala indima ebalulekile kumasu okuvikela kanye nokuzinza kwezwe. Sekukonke, amasathelayithi aguqule umphakathi wesimanje, athuthukisa ukuxhumana, ukuzulazula, ucwaningo, nokuphepha. Ukuthuthuka kwabo okuqhubekayo kuzothuthukisa amakhono abantu emkhathini naseMhlabeni.
