Zida za Satellite

Zomwe Zing'onozing'ono Zamakono ndi Zopangidwa

Mitundu ya satellites - Mbiri ya Satellites Pofuna kupeza ukuwonjezeka kwambiri mphamvu opaleshoni ndi mtengo wotsikitsitsa zotheka, kafukufuku m'dera la aya kutero. Choncho lingaliro la makina kutumiza mauthenga anaonekera atangobadwa Nkhondo Yachiwiri ya World, chifukwa mitundu iwiri umisiri osiyana kwambiri (mivi ndi mayikirowevu). Danga zaka inayamba mu 1957 ndi kukhazikitsidwa kwa woyamba yokumba Kanema Sputnik Ine ya FSU, amene anali kunyamula wailesi chabwino chimene panamveka chizindikiro pa mafurikwense 20 ndi 40 MHz. tenepa akhoza analandira mwa amalandira yosavuta padziko lonse kuchita woyamba mayeso HIV ndi phwando chizindikiro kuchokera mlenga lenga.

Zizindikiro za satellites Chinthu chofunika kwambiri ndizosiyana siyana zomwe zimaperekedwa ndi satellite telecommunication systems, kufalitsa kwakukulu kwa ma satellites kumagwiritsidwa ntchito kukhazikitsa maulendo akutali. Chinthu china cha satellites ndi chakuti amatha kusonkhanitsa kapena kufalitsa zizindikiro kuchokera kumalo osiyanasiyana kapena m'malo osiyanasiyana.

Kodi satesi ndi chiyani? Ndizobwezera zamagetsi zomwe zili m'malo, zimalandira zikwangwani zopangidwa padziko lapansi, zimazikulitsa ndi kuzibwezeretsanso padziko lapansi. Sitaneti ndi chinthu chilichonse chomwe chimayenda mozungulira kapena chikuzungulira chinthu china. Mwachitsanzo, mwezi ndi satana pa dziko lapansi, ndipo dziko lapansi ndi satana.

Kodi sataneti amagwira ntchito bwanji? Radiyo yamasewera "A" imatulutsa chizindikiro chomwe amalandira ndi satana. Satellite imakulimbitsa ndi kuyibwezeranso nthawi yomweyo. Wothandizira ma radio "B" amalandira izo ndikuyankha. Choncho yambani kuyankhulana ndi satana. Ma satellites olankhulana amachitanso ngati malo othawirako. Amagwiritsidwa ntchito kutumiza mauthenga kuchokera ku mbali imodzi ya dziko kupita kwina. Mauthengawa akhoza kuimbira foni, zithunzi za pa TV, kapena ma intaneti. Ma satellites olankhulana ngati EchoStar ali mu orbit geosynchronous (geo = earth + synchronous = kusuntha pamtunda womwewo). Izi zikutanthauza kuti satana imakhala nthawi zonse padziko lapansi. Dera la Padziko lapansi lomwe lingathe "Kuwona" limatchedwa satanic footprint.


Mitundu ya satellites:

Ndi njira yake:

Ø Ma satellites ozungulira magetsi. Pamene kanjira ndi mu ndege kunyanja ya Dziko Lapansi, pa mtunda wa pafupifupi 36000Km (lofanana 5,6 ndi utali wozungulira wa dziko lapansi), ndipo chotero, nthawi yozungulira ndi chimodzimodzi wofanana ndi nthawi kasinthasintha wa dziko lapansi (mwachitsanzo, 23 H, 56 Mph ndi 4s), lotchedwa tsiku sidereal, ndiye tinganene kuti kanjira ndi geostationary Kanema ndi kuthamanga kudutsa kanjira ichi ndi geostationary Kanema. Awa anali kufika kuyambira kwa aya Kanema, ndipo pafupifupi onse makina ntchito lero Intaneti aya makampani ndi Geo. Ntchito yaikulu ya nthambi izi ndi transmissions ndi mfundo ndi multipoint ndi mfundo ndi mfundo.

Ø ma satellites ozungulira omwe amatha kupitilira (LEO).Leo makina zili m'njira otsika, wa 1.500 makilomita pafupifupi koma akhoza kukhala pakati 200 ndi 2000 Km, nthawi yozungulira ali pakati pa 90 ndi 120 Mphindi. ovulala izi zili m'njira ankagwiritsa ntchito mu masiku oyambirira a sayansi ya mauthenga Kanema monga mmodzi wa magawo kuphimba kukwaniritsa cholinga chachikulu pa nthawiyo, zinali ilili geostationary, pamene komabe padali njira osakwanira kukwaniritsa mphamvu Launch chofunika kuika ilili mu 360000 Km phiko kutalika lolingana geosynchronous kanjira.

Cholinga chake:

Ø ma satellites owonetsa dziko lapansi.

Ø Ma satellites.

Ø ma satellites oyenda.

Ø ma satellites a telecommunication.

Ø Ma satellites a asilikali ndi azondi.

Ø ma satellites a ma radio.


Ubwino ndi Kuipa

Phindu

Ø Kugawidwa kwadzidzidzi kwa malo akuluakulu, mosiyana ndi kachitidwe kakang'ono ka nthaka, kazengereza kozengereza.

Ø Kukhoza kukhala wodziimira kutali ndi kutalika ndi zovuta zachilengedwe monga mapiri, ndi zina zotero.

kuipa

Ø Kutumizira satali kumayendedwe kawirikawiri, kufooka ndi mvula, chisanu ndi sunspots zomwe zimakhudza malo osungirako nthaka, zimayambanso kuwonetsa ma wailesi, microwave ndi kusokoneza ndege.

Ø mtengo wapamwamba.

Ø Nthawi ya moyo.

Ø Vuto lalamulo.


Satellite Ili ndilo gawo lalikulu ndi lofunikira la maukonde kudzera mwa gulu lomwe limagwirizanitsa palimodzi. M'lingaliro limeneli, lingathenso kulingalira ngati nthiti yamagetsi. Ntchito yaikulu ya satelesi yotumizirana telefoni ndi yotsatira: Ø Yambitsani zizindikiro zonyamulira zothandizira kubwezeretsanso pansi. Ø Kusintha kwafupipafupi kwa zizindikiro zonyamulira kuti tipeŵe kusokonekera Ø Satellite imakhala ndi malipiro komanso nsanja. Ø Kulipira kumaphatikizapo kulandira ndi kutumiza maina, ndi zipangizo zamagetsi zomwe zimathandiza kufalitsa zizindikiro zonyamula katundu. Ø Pulatifomu ili ndi zinthu zonse zomwe zimapereka malipiro kuti agwire ntchito.
