Zida za Satellite ndi Antennas



Kodi Satellite Ndi Chiyani?

Mfundo zazikulu zokhuza satana

Mafunso Ofunika pa Satellites

Kodi ma satellite amayamba bwanji? Mauthenga a pawailesi ya satana ndi zotsatira za kafufuzidwe mmalo mwa mauthenga, kuti athandizidwe kuwonjezeka kwakukulu pa ntchito zogulira pa mtengo wotsika kwambiri.

Ntchito zina zoperekedwa ndi satellites? Mu satellite telecommunication systems, mu maulendo akutali, amatha kusonkhanitsa kapena kulengeza zizindikiro kuchokera kumalo osiyanasiyana kapena m'malo osiyanasiyana.

Kodi satellite ndi chiyani? Ndizobwezera zamagetsi zomwe zili m'malo, zimalandira zikwangwani zopangidwa padziko lapansi, zimazikulitsa ndi kuzibwezeretsanso padziko lapansi. Ndipo imagwira ntchito chifukwa radiyo yamatsenga "A" imatulutsa chizindikiro chomwe chimalandira ndi satellite. Satellite imakulimbitsa ndi kuyibwezeranso nthawi yomweyo. Wothandizira ma radio "B" amalandira izo ndikuyankha. Choncho yambani kuyankhulana ndi satana.

Kodi ndi njira ziti za satellites zomwe zimagwiritsidwa ntchito kwambiri? Momwemonso ma satellites onse amagwiritsidwa ntchito lerolino kuti mauthenga ndi magulu a makampani ndi GEO. Zomwe zimagwiritsa ntchito ma satellite ndizofotokozera-mfundo-to-multi-point-to-point transmissions.

Zopindulitsa zina zogwiritsira ntchito mapulogalamu apamwambidwe apamwamba (MEO) Ma satellites a Earth Earth orbit ali pamtunda wa pakati pa 10075 ndi makilomita a 20150. Mosiyana ndi GEO (Geosynchronous Earth Orbit) malo awo apadera poyang'ana pamwamba sali okonzedwa. Pokhala pamtunda wotsika, pakufunika ma satellite ochulukirapo kuti athandizidwe padziko lonse, koma latency yachepa kwambiri.

Chiwerengero cha satellites ndi cholinga chawo kapena ma satellites omwe amawonetsa dziko lapansi. Mafunde a satellites. Ma satellites oyenda. Ma satellites. Satelite ndi azondi. Ham radio satellites.

Ntchito yaikulu ya satelesi yotumizirana telefoni Onetsani zizindikiro zonyamulira zothandizira kuti mubwererenso ku downlink. Komanso kusintha mafupipafupi a zizindikiro zonyamulira pofuna kupewa mavuto osokoneza

Zina mwa zomangidwe za satellite Satellite imakhala ndi malipiro komanso nsanja. Kulipira kumaphatikizapo kulandira ndi kutumiza ziphuphu, ndi zipangizo zamagetsi zomwe zimathandiza kufalitsa uthenga wonyamula zizindikiro. Pulatifomu ili ndi zinthu zonse zomwe zimapereka malipiro kuti agwiritse ntchito.

A satellite ndi dongosolo lopangidwa ndi machitidwe ang'onoang'ono. Ena mwa iwo ... Mfundo Zogwiritsa Ntchito Poyendetsa Mapulogalamu amachititsa kuti maulendo a satellites azikhala nthawi zonse. Njirayi imagwiritsa ntchito zizindikiro (monga maso), kotero satellita satell "amawona" kumene ikulozera. Sandeti yomwe imapangitsa sayansi kuwona ikufunikira kayendedwe ka kayendedwe kowonjezereka kusiyana ndi satelati. Malamulo ndi Mauthenga Azinthu Machitidwe oyendetsa ma data ndi malemba ndi omwe amagwira ntchito zonse za ndege (satellite). Njira Yothandizira Mauthenga Othandizira mauthengawa ali ndi zotumiza, ovomerezeka, ndi maina angapo kuti atumize mauthenga pakati pa satana ndi nthaka. Kulamulira kwa nthaka kumagwiritsa ntchito kutumiza malangizo opangira kompyuta yanu. Ndondomekoyi imatumizanso zithunzi ndi deta zina zomwe satana amapita kwa akatswiri pa Earth. Mphamvu za satana Zonsezi zimagwiritsa ntchito mphamvu zogwira ntchito. Dzuŵa limapereka kuti mphamvu kwa satellites ambiri ikuyendayenda padziko lapansi. Njirayi imagwiritsa ntchito mphamvu za dzuwa kuti zipange magetsi kuchokera ku dzuwa, mabatire kuti asunge mphamvu, ndi kuzigawira kwa zipangizo zonse mu satellite. Kulipira kwaumishoni Kulipira ndizomwe zipangizo zomwe satana amafunika kuchita. Ndi zosiyana pa ntchito iliyonse. Sandeti ya mauthenga amafunika ziwonetsero zazikulu zazikulu kuti zitumize TV kapena telefoni. Sandeti yojambula zithunzi za Dziko lapansi imafuna kamera ya digito kuti imvetse zithunzi zapansi pa dziko lapansi. Sandeti yowunikira sayansi imakhala ndi ma telescope ndi zithunzi zojambula zojambula nyenyezi ndi mapulaneti ena.

Tsogolo labwino pakukula ma satellites Kupititsa patsogolo ma satellite oyenera kusintha, omwe ali ndi zida zogwiritsira ntchito sampler zomwe zimaphatikizidwa mu sateleni zokhazokha ndizokhazikitsa zizindikiro zonyamulira. Kugwirizana kwa ma-inter-satellite, zomwe zingachepetse nthawi yofalitsa pakati pa maulumikizi omwe ma satellita angapo amalowererapo. Kugwiritsa ntchito maulendo apamwamba (30 / 20 Ghz.) Ndi 50 / 40 Ghz.); Pakalipano, maulendowa amachititsa mavuto otsekemera kwambiri, makamaka chifukwa cha mvula.


Anatomy of Satellite:

Dzuwa Zojambula za dzuwa ndizitali zazikulu zomwe zimapangidwa ndi maselo ambirimbiri a dzuwa. Selo lirilonse limapanga magetsi kuchokera ku dzuwa. Maselo onsewa atagwirizanitsidwa palimodzi, amapanga mphamvu zambiri zomwe zidzatsegula zipangizo za satana ndi kutulutsa mabatire a satellite.

Blanc yotentha Kabulangete yotentha ndi gawo la mawonekedwe a kutentha. Chovalacho chimapangidwa ndi zinthu zochepa zomwe zimaphimba satana, ndipo zimagwira ntchito zotsatirazi: zimapangitsa satana kutentha kuchokera kuzizizira komanso kuzizira kutentha. Ma satellites amadziwika kuti amazizira kwambiri (-120 mpaka + 180). Popanda bulangeti yotentha, chinthu chophweka chamagetsi chingawonongeke.

Batery Battery ndi gawo la mphamvu. Sungani mphamvu zamagetsi zomwe zimapangidwa ndi dzuwa kuti zigwiritsidwe ntchito ndi zipangizo zamagetsi zonse za satellita.

Mabungwe a Mabasi Chigawo chofunikira cha satana ndi chimango chomwe chimagwirizanitsa pamodzi. Kapangidwe kabasi kawirikawiri kamapangidwa ndi zinthu zowala kwambiri komanso zosagwira ntchito zomwe zingakhale zolimba kuti zithandize mbali zonse, koma osati zolemetsa kotero kuti satana silingakhoze kukwezedwa mu mphanda.

Otsatira nyenyezi Otsatira nyenyeziwo ali mbali ya gawo lolamulira. Ndife telescopes yaing'ono yomwe ikusowa malo ndi kuwerenga malo a nyenyezi. Ma satellites amagwiritsa ntchito malo a nyenyezi kuti aziyenda, monga momwe timachitira padziko lapansi.

Magudumu okhudza Magudumu amachitiranso ndi mbali ya mphamvu yoyang'anira. Izi zimatulutsa satanazo m'njira zosiyanasiyana. Mphamvu yake imachititsa kuti satanayo isunthidwe ndi kutchula zina mwachindunji.

Owonetsa O / O Chowongolera-zotuluka pulojekiti ndi gawo la deta ndi kulamulira gawo. Iwo amayendetsa kutuluka kwa deta mkati ndi kuchokera ku kompyuta yopulumukira.

Omni Antennas The omni antenna ndi gawo la mauthenga. Zimagwiritsidwa ntchito pofalitsa mauthenga pakati pa satellite ndi dziko lapansi.

Ndege ya ndege Kompyuthamanga yopanga ndege ndi mbali ya deta komanso malamulo. Uwu ndiwo ubongo wa satellita womwe umalamulira ntchito zonse pa satellites.

Kutumiza / kulandira Kutumiza / kulandila ndi mbali ya machitidwe a mauthenga. Pamene ma satellita amayenera kutumiza fomu, nthaka imasintha chiwonetsero cha fano kukhala chizindikiro chomwe chikhoza kugwiritsidwa pansi. Pamene injini imatumiza lamulo ku satellite, satelesiyo imatenga chizindikiro ndikutumiza kusintha kwa uthenga umene kompyuta yanuyo imatha kumvetsa.

Gawo la padziko lapansi Icho chimapangidwa ndi malo onse apadziko lapansi; izi nthawi zambiri zimagwirizanitsidwa ndi wogwiritsa ntchito yomaliza kudzera pazithunzithunzi zapadziko lapansi, kapena pa malo ochepa, ogwirizana kwambiri ndi zipangizo za wogwiritsira ntchito.
