Intanethi ye-Intanethi ngee-Antennas eziLwazi ngokuZenzekelayo



Yintoni i-Satellite?

Iingcamango ezisisiseko malunga ne-satellite

Imibuzo Eyisiseko ngeSatellites

Zivela njani i-satellites? Ukunxibelelana ngothungelwano lwe-intanethi yiphumo lophando kwiindawo zonxibelelwano, ukwenzela ukuba ufumane ukwanda okukhulu kwamandla okusebenza kwindleko ephantsi kakhulu.

Ezinye iinkonzo ezinikezelwa ngama-satellites? Kwiinkqubo zokunxibelelana nge-satellite, kwiindawo ezinokude, nazo zinokukwazi ukuqokelela okanye ukusabalalisa iimpawu ukusuka kwindawo okanye kwiindawo ezahlukeneyo kunokuba zithunyelwe ukusuka kwenye indawo ukuya kwenye.

Yintoni i-satellite kwaye isebenza njani? I-repeat ye-elektroniki ehlala kwindawo, ifumana iimpawu eziveliswa emhlabeni, ziyakhulisa kwaye zibuyisele emhlabeni. Kwaye isebenza ngenxa yokuba umsakazo onomculo "A" uthumela uphawu olufunyenwe yi-satellite. I-satellite iyakwandisa kwaye ibuyise kwakhona ngokukhawuleza. Umnxeba we-radio "B" uyamkela kwaye uyiphendule. Ngoko qalisa uqhagamshelwano lwe-satellite.

Ziziphi ii-satbiti ezisetyenziswa kakhulu? Ngokuqhelekileyo onke ama-satellites asetshenzisiweyo namhlanje ukunxibelelana ngamanethiwekhi ezinkampani yi-GEO. Izicelo eziphambili zezi satellites zibonisa ukutshintshwa kweengongoma.

Ezinye iingenelo zokusebenzisa ama-satellites aphakathi kwe-orbital (MEO) Ama-satellites aphakathi kwe-Earth orbit aphakamileyo phakathi kwe-10075 kunye neekhilomitha ze-20150. Ngokungafani ne-GEO (Geosynchronous Earth Orbit) isikhundla sabo esifanelekileyo ngokubhekiselele kumhlaba asilungisiweyo. Ukuba kwindawo ephantsi, kukho inani elikhulu lama-satellites ukuze kufumaneke ukukhawulwa kwehlabathi, kodwa i-latency iyancitshiswa kakhulu.

Ukwahlula ama-satellites ngenjongo okanye kwi-satellite observation. Satellites zeMeteorological. Satellites zokuhamba. Satellites. Ama satellites aseMpi kunye neentlola. Satellites zeHam.

Imisebenzi ephambili ye-satellite telecommunications Ukutshintshela iimpawu zephatha zokufumana ukubuyisela kwakhona kwi-downlink. Kanye nokutshintsha ubukhulu beempawu zokuthintela ukukhusela iingxaki zokuphazamiseka

Olunye lwezakhiwo ze-satellite I-satellite iquka umrhumo wokuhlawula kunye neqonga. Ukuhlawula umrhumo kubandakanya ukufumana kunye nokuthumela i-antenna, kunye nezixhobo zecomputer ezixhasa ukuhanjiswa kweenkcukacha ezithwala iimpawu. Iqonga liquka zonke iissystem ezenza ukuba umrhumo wokuhlawula usebenze.

I-satellite iyinkqubo eyinkimbinkimbi ehlanganiswe neenkqubo ezincinane ezincinci. Ezinye zazo ... Amanqaku okuLawula Inkqubo yokuPhathwa kweeNgcaciso igcina isalathiso kwixesha le-satellites rhoqo. Inkqubo isebenzisa iicensors (njengamehlo), ngoko i-antenna ye-satellite "ibona" ​​apho ibonisa khona. I-satellites eyenza ukuba uphando lwezenzululwazi ludinga inkqubo yolawulo oluchanekileyo ngakumbi kune-satellite satellite. I-Command and Data Subsystem Iinkqubo zolawulo zokucwangciswa kwedatha kunye nemiyalelo yilabo abaphethe yonke imisebenzi ye-spacecraft (i-brain satellite). Ishini seshini Inkqubo yokunxibelelana ine-transmitter, receiver, kunye nee-antenn eziliqela ukuthumela imiyalezo phakathi kwe-satellite kunye nomhlaba. Ulawulo lomhlaba ulisebenzisa ukuthumela imiyalelo yokusebenza kwikhomputha ye-satellites. Le nkqubo iphinda ithumele imifanekiso kunye nedatha efunyenwe yi-satellite ukubuyela kwiinjineli emhlabeni. Ukunikezelwa kwamandla Wonke ama-satellites asebenzayo ayadinga amandla okusebenza. Ilanga linikeza ukuba amandla kwiindawo ezininzi zasesatellite zihamba ngokujikeleza emhlabeni. Le nkqubo isebenzisa i-solar arrays ukwenza ugesi kwi-sun, ibhetri ukuze igcine amandla, ize isasaze kwizixhobo kuzo zonke i-satellite. Umrhumo wokuhlawula umvuzo I-Payload zonke izixhobo ze-satellite kufuneka zenze umsebenzi wazo. Kuhluke kumsebenzi ngamnye. I-satellite satellite kufuneka idinga i-antenna ebonisa ukuthumela i-TV okanye i-Phone. I-satellite yokuthatha iifoto zomhlaba idinga ikhamera yedijithali ukuthatha imifanekiso yoMhlaba. I-satellite yesayensi yenzululwazi idinga i-telescope kunye neentlobo zengqondo ukurekhoda ukubukwa kweenkwenkwezi nezinye ieplanethi.

Ikamva ekuphuhliseni ama-satellites Ukulindeleka kokuphuhliswa kwama-satellites okuhlaziywa ngokutsha, okuya kuba ne-sampler yokufakelwa kwezixhobo ezifakwe kwi-satellite ngokwayo kwaye ziza kuphucula izibonakaliso eziphathekayo. Izixhumanisi ze-inter-satellite, eziza kunciphisa ixesha lokusasaza phakathi kwamaqhagamshelwano apho amaninzi amaninzi angenelela khona. Ukusetyenziswa kwamaziko aphakamileyo (30 / 20 Ghz. Kunye ne-50 / 40 Ghz.); Okwangoku, ezi zikhulu zibangelwa iingxaki eziphezulu kakhulu zokunakekelwa, ikakhulu ngenxa yemvula.


I-Anatomy yeSatellite:

Iillar Arrays Izixhobo zelanga zizakhiwo ezinkulu ezenziwe ngamawaka amancinci elanga elanga. Iselinye ngasinye sivelisa umbane kwilanga. Xa zonke iiseli zixhunyiwe kunye, zivelisa amandla amaninzi eziza kuvula izixhobo ze-satellite kwaye zikhuphe iibhetri ze-satellite.

Blanquet eshushu Ingubo ye-thermal iyinxalenye yeseshishini yolawulo lwe-thermal. Ingubo yenziwe ngumbumba omncinci obandakanya i-satellite yonke, kwaye wenza imisebenzi elandelayo: igcina i-satellite efudumele efudumele kwaye ipholile ekushiseni. Ama-satellites abonakaliswe kwiqondo lokubanda kakhulu kwaye kushushu kakhulu (-120 ukuya ku-180). Ngaphandle kwengubo ye-thermal, into ebuthakathaka yecomputer iya kubonakaliswa.

Batery Ibhethri inxalenye yeshini sessystem. Gcina umbane wamandla owenziwe yimizila yelanga ukuze isetyenziswe zonke izixhobo zombane ze-satellite.

Izakhiwo zeBhasi Isiqabana esibalulekileyo sesathelayithi yisakhelo esilugcina ndawonye. Isakhiwo sebhasi sivame ukuba senziwe ngezinto ezibonakalayo ezikhanyayo kwaye ezinqabileyo kakhulu eziya kuzinzela ngokwaneleyo ukuxhasa zonke iziqwenga, kodwa zingenzima kangangokuthi i-satellite ayikwazi ukuphakanyiswa kwi-orbit.

Abaqhubi beenkwenkwezi Abaphandle inkwenkwezi bayinxalenye yeshini sessystem. Ziyi-telescopes encinci efuna indawo kwaye ifunde indawo yeenkwenkwezi. Ama-satellites asebenzisa indawo yeenkwenkwezi ukuhamba, njengokuba sisenza emhlabeni.

Amasondo afanayo Amasondo asabelayo nawo ayinxalenye yeshini sessystem. Ezi zijikeleza i-satellite kwiindlela ezahlukeneyo. I-Force yayo ibangela ukuba i-satellite ihambe kwaye ibhekiselele kwiindlela ezithile ezithile.

I-O Inkqubo Inkqubo yenkxaso-mphulo yinkqubo yenkcazelo yedatha kunye nomyalelo wesiseko. Balawula ukuhamba kweedatha ngaphakathi nakubakhompyutha.

Omni Antennas I-omni antenna inxalenye yenkqutyana yeshini. Zisetyenziselwa ukuhambisa imiyalezo phakathi kokulawulwa kwe-satellite kunye nomhlaba.

Ikhomputha yekhompyutha Ikhompyutheni yendiza inxalenye yedatha kunye nomyalelo wesiseko. Le ngongoma yesatellite esilawula yonke imisebenzi kwi-satellites.

Umthumeli / umamkeli Umthumeli / umamkeli uyinxalenye yessystems yoqhagamshelwano. Xa ama-satellites adinga ukuthumela ifreyimu yomhlaba, umtshintshi utshintsha idata yesithombe kwisibonakaliso esinokukhishwa phantsi. Xa iinjineli zithumela umyalelo kwi-satellite, i-satellite receiver ikhetha uphawu kwaye ithumela utshintsho kwisigidimi ukuba ikhompyutha ye-satellite iyakwazi ukuyiqonda.

Icandelo lomhlaba Iqukethe zonke izikhululo zomhlaba; Ezi zinto zihlala zixhunyaniswe nomsebenzisi wokugqibela ngokusebenzisa inethiwekhi yomhlaba, okanye kwimeko yezitishi ezincinci, ezixhomekeke ngqo kwisixhobo somsebenzisi wokugqibela.
