Impambaniso libalele. Sun kokulungisa. ukuxhumana satellite

Abanikazi satellite dishes izohlanganiswa ngesinye babhekene eside ezifana "ukuphazamiseka welanga". ngokuvamile Lokhu kwenzeka ngonyaka wokuqala wokusebenza we-antenna lapho umhlinzeki ngokwalo liyaxwayisa abasebenzisi mayelana nokwenzeka isignali ukulahlekelwa, nje ngenxa yalesi sizathu. Asizwise lokhu ukuthi kuyini nokuthi kungani ukudluliswa isignali yomsakazo kahle noma baphelelwa.

Uyini ukuphazamiseka solar

Noma yimuphi izinkanyezi, kuhlanganise Sun yethu likhipha ukukhanya amandla hhayi kuphela ebonakalayo, kodwa futhi amagagasi omsakazo in the uhla isentimitha. Lapho ilanga emgceni locondzile kusukela satellite kanye antenna satellite TV, isiginali reception akunakwenzeka. Zonke ngenxa yokuthi ilanga akakubangeli ukuphazamiseka okuyingozi, futhi amasignali transponder kuyendlulela imisindo banal ukusuka elangeni.

Uma lokhu kwenzeka

Lesi simo esiyingqayizivele sibangelwa senzeka izikhathi 2 ngonyaka - entwasahlobo and ekwindla. Kuyinto kulezi zonyaka ukuphazamiseka solar kungenzeka. Ngokuvamile lokhu kwenzeka amasonto 3.5 kusukela ezinsukwini entwasahlobo and ekwindla nelanga. Ngalesi sikhathi, ilanga kwenza umgwaqo yonyaka kokuwela indiza yenkabazwe.

Ngo-February no-March, ukuphazamiseka lokuqala kuthinta iziteshi emhlabeni, okuyinto zitholakala kule zindawo enyakatho, eminye ihlanganisa iziteshi eyamukelayo eningizimu. Enkabazwe, iyona isiqongo lokhu mkhuba uwela ngo-September 21 (ngesikhathi sokulingana kwemini nobusuku). Khona-ke esifundeni ushukumiseleka ukuba Nenkabazwe oseningizimu. Kuyinto iziteshi eningizimu ethola uhlangabezana umthelela yakamuva ukuphazamiseka elanga, okuyinto uphela ngemva kwamasonto 3.5 ngemva sokulingana kwemini nobusuku entwasahlobo.

Agasti, Septhemba, Okthoba has ahoxise isithombe, ngoba ilanga uqala ukunyakaza kolunye uhlangothi - e Nenkabazwe aseningizimu eNyakatho. Phakathi nale nkathi, ngoba inkathi esiteshini ukuphazamiseka ngamunye uyaqhubeka ngeviki. Nsuku zonke kuphazamisa ukusebenza phakathi nalesi sikhathi. Futhi ekuseni ithonya empumalanga ukuxhumana amenable iziphuphutheki, kusihlwa - eNtshonalanga.

Kanjani ukuthi kuziveza

Okokuqala, ngesikhathi umthelela ababuthakathaka esikrinini TV zingavela umsinjwana, okuyinto buyaqina emini. Sesinamandla ukuphazamiseka elanga akunasiginali kusukela satellite nhlobo. Ngakho ungakhathazeki ngakho ucabange ukuthi unayo kukhona into ephukile noma sehla bebheke antenna. Okufanele oda, futhi lesi simo kuyinto evamile.

Okufanele ukwenze

Ngo iningi isiqongo isignali phakathi libalele, kuyinto efiselekayo buyisela-antenna enentambo satellite nhlobo. Lokhu kwenziwa ukuze izingxenye plastic irradiators hhayi ancibilike. Kungaba ukubhekana ukuwohloka ephelele electronics converters. Ngenxa yalokhu, i-aluminiyamu reflectors kakhulu "yimpumelelo" ukugxilisa ingqondo yelanga endaweni eqondile.

Ngakho kwaba njalo endabeni ka ukuphazamiseka eqinile noma ukulahleka ingqikithi isignali satellite, ubuze ISP yakho ukuthi Ilanga laphuma ukuphazamiseka noma isignali kulahleka nganoma isiphi esinye isizathu. Uma lokhu umphumela ukuphazamiseka, bese uya ophahleni (noma lapho ozifakile antenna) bese ukuhambisa ngakuwe. Bese makahlale kufanele kabusha ngqo satellite. Lokhu ungcono kokuchitha imali ku entsha electronics converters. Nakuba zikhona izindlela kulula. Ngokwesibonelo, ungakwazi nje amboze lutho antenna opaque, engayivumeli imisebe yelanga.

Solar ukuphazamiseka umonakalo

Ngokuyinhloko ngenxa ukuphazamiseka solar kuthinta nomsakazo nomabonakude iziteshi, okuyinto retransmit le yengeza izitshengiselo ezivela kwamanye ukusakaza satellite. Ngenxa yalokho zalesi simo, balahlekelwa isiginali, okuyinto igcwele umshado emoyeni futhi ukulahlekelwa simo. Ngakho-ke, zonke inkampani self-ukuhlonipha ukulungiselela imithombo isignali futhi ushintshe kuzo phambi ukuphazamiseka kwelanga ukuza ngokugcwele phakathi force.

Nanenkinga iziteshi ukuthi ukwamukela isignali yomsakazo kusuka kumasathalayithi "Express" futhi "Horizon". Isici lezi iziphuphutheki kuyinto ngokunyakaza ku-orbit ezintweni ezingafanele. Ukwamukela isignali abamukelayo asetshenziswa Pansat XR4600D, Drake ESR-700 futhi ESR2000XT-plus. Ngenxa yalokho we ukuphazamiseka yalezi abamukelayo kungaba "aphelelwe 'iziphuphutheki futhi baqala ethungatha ilanga. Ngakho-ke kubalulekile ukuba pre-hlelo abamukelayo lezi iziphuphutheki ekhatshana futhi khubaza sokulandela phezu okuvela into enjalo. Lapho ukuphazamiseka sihamba, abamukelayo zidinga uhlelo lezi izinyanga njengoba iziphuphutheki nge ukuthambekela esemkhathini. Zonke lezi zenzo kumele kwenziwe izikhathi 2 ngonyaka, kanti izindleko esingeziwe umzamo. Nokho, uma isamukeli owamukelayo akusetshenziswa, ungavele basibeka Stanby isikhathi isiphazamiso welanga.

Iziteshi Okokugcina abathintekayo ethola amasignali kusuka iziphuphutheki "Express" futhi "Horizon" nge omise ezintweni ezingafanele. Ngezinye izikhathi, ngesikhathi ukuphazamiseka singenzeka isheke amatafula kokulandela idatha. Uma ngalesi sikhathi isilawuli uyakuletha phezu ilanga, kuyoba konakalisa lonke irowu kwethebula. Ngenxa yalokho eziphindaphindiwe ukwehluleka reception akunakugwenywa ngisho uma Impambaniso ungayibona kuhle useqede ngosuku lwesibili. Ngakho-ke, isilawuli is inqanyuliwe kunethiwekhi kusengaphambili futhi, ngemva kokubuyiselwa kwezimo ezivamile reception ulifake futhi. Into esemqoka - ungaphuthelwa kube yilo mzuzu.

abasebenzisi avamile abasebenzisa ezinkulu-ububanzi antenna, nabo bangase bahlupheke. Ngo lisile imisebe yelanga bagxile Converter yilo antenna uqobo. Converter heats futhi kungaba ancibilike. Ngakho liyashona, umsebenzisi kuyodingeka esikhundleni salo esisha. Ngakho hlala ubukele ukuphazamiseka solar nesenzakalo yayo noma naba antenna bebheke, noma alisibekele amakhadibhodi noma ifilimu opaque. Kungenjalo, emisebeni kwelanga ngo-antenna ancibilike abamukelayo.

Isikhathi ukuphazamiseka

Kukhona izinhlelo ekhethekile sithole isikhathi nesenzakalo ukugxambukela welanga. Omunye wabo okuthiwa Bheka, futhi basakaza mahhala kuwebhu. Uhlelo ilula futhi ngisho bakudala, kuvele sikhombisa usuku oluqondile lapho zinsimbi ngesikhathi esiphezulu. Futhi, kungakusiza ukwazi ngezinsuku zokuqala nezokugcina we "Iseshini" we ukuphazamiseka. Ukuze wenze lokhu, kusukela ngalolo suku kufanele ubale inani izinsuku emuva naphambili. Inani lezinsuku njengoba kunqunywe hlelo, kuye wathi ubukhulu ezahlukene kanye antenna. Kodwa kuyafaneleka ukuthi lolu hlelo lusebenza kuphela iziteshi kokuthola yeNyakatho Nenkabazwe.

Calculator sokunquma ukuphazamiseka

Uma ungakwazi ukuthola noma ungafuni ukuba kuzamazame uhlelo ngenhla, ungasebenzisa i wokubala inthanethi. Yena limelelwa PanAmSat indawo. Nokho, ukusebenza ke udinga ukuthi ube enye idatha.

Ngokwesibonelo, kubalulekile ukwazi ukuthi isikhundla satellite esemkhathini (ungakhetha usesho, noma ngesandla oyifakile), izixhumanisi esiteshini eyamukelayo (ungakhetha uhlu ecacisiwe umuzi wabo), imvamisa ububanzi, ububanzi antenna kwesizini. Uma yonke idatha onayo, kufanele ayifake i wokubala inthanethi bese uchofoza "Bala". Lolu hlelo luzo luzosiza siqala futhi siphele ngesikhathi isiphazamiso. Yonke idatha uzobe esibekiwe ku-HTML format, ukuze ukwazi ukuphrinta nabo babamba odongeni njalo ukhumbule lokhu.

Ukusebenza wokubala

Qaphela ukuthi nakuba lolu hlelo futhi useyakwazi ngokwezinga elikhulu e-US, lusebenza zonke iziteshi kokuthola. Nokho, zikhona ezinye izici lolu hlelo:

1. Lapho bengena ubukhulu antenna kumele ufake amanani elinezinhlamvu idesimali usebenzisa iphuzu, kunokuba comma. Kungenjalo, lolu hlelo luyoba hang futhi akukho ukubala ngeke.
2. Isethelayithi izikhundla akhonjiswa ngokwamazinga entshonalanga-longitude yakho ukusuka 0 360 W (entshonalanga we Greenwich Meridian). Ngakho-ke, i-iziphuphutheki e-Eastern Nenkabazwe kumele ufake ukubaluleka uphawu "lokususa".
3. Futhi-ke ungayididanisi nezinsuku. E-US, bhala usuku kanje: ". Oneminyaka engu sezinsuku ezingu-ngenyanga" Thina zisetshenziselwa ukhombise usuku ngokuthi "-nyaka ngenyanga-suku."

Ngokuvamile, lokhu wokubala kwanele ukuba sinikele ngokunembile ukuqala ukuphazamiseka futhi akwaziwa nokuthi liyophela. Kodwa uma ungayiqondi ke vakashela izinkundla thematic kumabonakude satellite. Kukhona ngokuvamile iyitimu ekutholweni ukuphazamiseka ngenxa emadolobheni ahlukene. Ngaphezu kwalokho, abanye abahlinzeki ukuxwayisa abasebenzisi mayelana okuvela kuyo le nkathi, ngisho ukunikeza amathiphu kanjani ukukulungisa "ukusinda."
