Kutsimikiza kwa ma coordinates, azimuth ndi ngodya yokwezeka ya mbale ya satellite

Kuloza “mbale” ya satellite pa satelayiti ndi njira yosavuta, koma pamafunika kuti munthu akhale ndi luso lofunikira pogwira ntchito ndi zida za mlongoti. Nthawi zambiri, tikulimbikitsidwa kuyika ndondomekoyi kwa katswiri wodziwa bwino, koma ngati pazifukwa zilizonse (chinthu chotetezeka, malo akutali, ndi zina zotero) sizingatheke kugwiritsa ntchito ntchito zake, ndiye kuti mukhoza kuyesa kusintha mlongoti nokha .

1. Kulumikizana kwa malo a antenna . Mutha kudziwa zolumikizira m’njira zingapo – kugwiritsa ntchito GPS navigator, kugwiritsa ntchito mapulogalamu monga GoogleMaps ndi zina zotero, pogwiritsa ntchito mapu a malo kapena njira ina yomwe ilipo. Ngati muli ndi foni yam’manja ndipo muli pamalo ochezera pa intaneti, kudziwa zolumikizira sikuyenera kukhala kovuta.
2. Kukwezeka ndi azimuth kupita ku satellite . Mphindi wofunikira kwambiri pakukonza mlongoti. Ngati izi sizikudziwika bwino poyambirira, ndiye kuti muwadziwe, ndi bwino kugwiritsa ntchito imodzi mwama intaneti, mwachitsanzo, chowerengera chaulere pa intaneti “Satcalc”.

Chitsanzo chowerengera njira yopita ku satellite pogwiritsa ntchito chowerengera

Ganizirani za njira yodziwira komwe mlongoti akuloza pogwiritsa ntchito chitsanzo cha satellite ya Express AM3 mumzinda wa Vladivostok. Timazindikira makonzedwe a malo oyika antenna ndi njira iliyonse yomwe ilipo. Kwa mzinda wa Vladivostok, zolumikizira zidzakhala ndi izi – latitude: 43°06′20″, longitude: 131°52′24″ E. Pitani patsamba lowerengera pa intaneti. [id id mawu = “attach_3482″ align=”aligncenter” wide=”595″]

Kusankha malo oyika

Mukayika mlongoti, muyenera kuganizira kwambiri zinthu zitatu.

1. Malo otseguka kwambiri kumayendedwe a satana , moyenera mzere wolunjika, osatsekedwa ndi nyumba, mitengo, mapiri amtundu. [id id mawu = “attach_3472” align = “aligncenter” wide = “450”] Kusankha malo oyenera oyikamo mbale ya satellite ndi ntchito yoyamba[/caption]
2. Kudalirika kwa kukwera kwa mlongoti . Monga lamulo, galasi la satellite mbale, chifukwa cha mapangidwe ake, imakhala ndi mphepo yowonjezereka ndipo, ngati sichimangirizidwa bwino, idzachoka ku mphepo.
3. Sungani mtunda waufupi kuchokera ku mlongoti kupita ku cholandirira satellite mwachidule momwe mungathere . Chowonadi n’chakuti chingwe chilichonse chimayambitsa coefficient yake yochepetsera – ndiko kuti, imachepetsa mlingo wa chizindikiro chothandiza. Pachifukwa ichi, ngakhale mutagwiritsa ntchito chingwe chapamwamba, sikulimbikitsidwa kusuntha mlongoti kutali ndi wolandila ndi mamita oposa 20-25.

Malo osankhidwa okwera ayeneranso kupereka mphamvu yozungulira galasi la mlongoti ndi madigiri 10-14 kuchokera ku azimuth axis. Ngati pali chopinga chachilengedwe (chopanga) polowera satelayiti patali pang’ono, mutha kuyesa kudziwa kuchuluka kwa zomwe zingakhudze pamtundu wolandila.
Kuwerengera, ndikofunikira kudziwa pafupifupi mtunda wa chinthucho ndi kutalika kwake (mwachitsanzo, poyerekeza kutalika kwa zinthu zomwe zili pafupi ndi kutalika kwake komwe kumadziwika), kenako pogwiritsa ntchito mawerengedwe a trigonometric kapena mautumiki aliwonse a intaneti, kuwerengera ngodya ya kukwera kwa chinthu. Ngati mtengo womwe wapezedwa sudutsa mtengo wa ngodya yokwera (kukwera), ndiye kuti palibe chodetsa nkhawa, apo ayi muyenera kusankha malo ena kuti muyike mlongoti kapena kugwiritsa ntchito chithandizo kuti muwonjezere kutalika.

Kuzindikira makonzedwe a malo anu kuti muyike mbale ya satana – izi ndizofunikira kuti muwerenge azimuth ndi kutalika kwa mbale ya satana pogwiritsa ntchito chowerengera kapena pulogalamu yapadera:

Kuyika zida za mlongoti

Njira yokweza mlongoti imayamba ndi kusonkhana kwake. Mukamasonkhanitsa, muyenera kuyang’ana kwambiri zomwe wopanga amapanga. Monga lamulo, mlongoti umabwera ndi malangizo atsatanetsatane osonkhanitsa, kusonyeza magawo akuluakulu. [id-caption id = “attach_3466” align = “aligncenter” wide = “540”]
Kuyika mbale ya satelayiti[/ mawu] Mlongoti wolumikizidwa bwino umayikidwa pamaziko okhazikitsidwa kale ndi olimbikitsidwa, pomwe zolumikizira zomata zimagwira ntchito pozungulira. galasi la mlongoti mu ndege zowongoka ndi zopingasa sizimangirira njira yonse. Kuyika kwa chosinthira kumayenera mawu apadera. Chosinthiracho chimayikidwa poyang’ana mlongoti wosonkhanitsidwa kwathunthu ndikuzungulira pamtengo wopezeka mu pulogalamu ya Satcalc pagawo lowerengera azimuth ndi ngodya yokwera. Mtengo womwe uli mugawo la LNB Rotation ukuwonetsa kuti LNB ikufunika kuzunguliridwa ndi madigiri 46 motsatana ndi koloko kuchokera koyima. Kuti mukhale wosavuta kukhazikitsa ngodya, zolembera zimayikidwa kutsogolo kwa chosinthira kuwonetsa “Zero position” ndi sikelo ya angular. Chomaliza pakuyika mlongoti ndikulumikiza chingwe ku chosinthira cholembedwa.

Kusintha kwa antenna

Zakudya za satellite zimagawidwa kukhala “Direct Focus” ndi “Offset”. Mutha kuwasiyanitsa onse powerenga zolembedwa zomwe zaphatikizidwa, ndipo zowoneka – zolunjika mwachindunji zimakhala ndi masinthidwe ozungulira, kalilole wa tinyanga tating’onoting’ono tokhala ndi mawonekedwe a ellipse (yotalikirapo molunjika ku nkhwangwa zowongoka). Iliyonse ya tinyanga ili ndi zolozera zake – ndege yagalasi ya mlongoti wolunjika mwachindunji imalunjikitsidwa ku satelayiti panthawi yokonzekera molingana ndi kukwezeka kwa data. Mlongoti wothandizira ali ndi zowonjezera zowonjezera – “offset angle”, mtengo wake ukhoza kupezeka muzolemba za mlongoti.Mukakhazikitsa antenna yochotsera, malo ofunikira a ndege yagalasi amawerengedwa ndi ndondomeko – ƛp = ƛm – ƛs. Kumene ƛp ndi malo ofunikira a kalirole wa mlongoti wotsatizana ndi chopingasa, ƛm ndi ngodya yokwera yowerengedwa ndi njira ya mapulogalamu, ƛs ndi mbali yolumikizira yotchulidwa mu pasipoti ya mlongoti. Zimachitika kuti mutatha kuwerengera, mtengowo umapezeka ndi chizindikiro chochotsera, zomwe zikutanthauza kuti galasi loyang’ana mlongoti liyenera kupendekera pansi ndi mtengo wa ngodya yomwe yapezeka.
Azimuth ndi ngodya yokwera ya mbale ya satellite imatha kuwerengedwa popanda chowerengera – kudzera munjira zotsatirazi:

“Sakani” satellite

Kuloza molunjika kwa mlongoti ku satelayiti kumatha kugawidwa m’magawo awiri. Pa gawo loyamba, kusintha “kovuta” kumapangidwa, pachiwiri kumakhala komaliza. Kuwongolera kolimba kumatanthauza kuloza mlongoti pa satelayiti mu azimuth ndi kukwera. Kuti tichite izi, galasi la mlongoti limakwezedwa ndi ngodya yowerengeka yokwera (potengera mbali yochepetsera ya mlongoti wokha). Panthawi imeneyi, goniometer yolumikizidwa ku ndege ya mlongoti idzakhala yothandiza.
Kuwongolera kwa azimuth kumachitika pogwiritsa ntchito kampasi. Palinso njira yolozera “molingana ndi dzuwa”, imapereka zotsatira zabwino, koma pochita anthu ochepa amagwiritsa ntchito chifukwa cha kuchepa kwake (mtambo, sikutheka nthawi zonse kuwerengera malo enieni a dzuwa pa nthawi yoyenera. , ndi zina). Kusintha komaliza kumapangidwa ndi kuphatikiza mita yapadera – “SatFinder” mumpata wa chingwe pakati pa chosinthira ndi cholandila satana. Mamita amatha kukhala oyimba osavuta komanso ovuta kwambiri digito. Mulimonsemo, aliyense wa iwo amachita ntchito zawo.
Kuti mukonze bwino, masulani mabawuti a mlongoti ndikuzungulira pang’onopang’ono mu azimuth, kuyesera kuti asapitirire liwiro la 1 digiri pa sekondi iliyonse. Pambuyo pojambula chizindikirocho, njira zokhotakhota zazing’ono (kumanzere / kumanja) ziyenera kukwaniritsa mlingo waukulu wa chizindikiro ndikukonza mlongoti. Ngati chikwangwani chikuwoneka, koma sichimakhudzidwa ndi kutembenuka kwagalasi kapena mtundu wake ndi wosakhazikika, tikulimbikitsidwa kupotoza mlongoti ndi madigiri a 1-2 motsatana ndi mayendedwe okwera. Zotsatira zabwino mu nthawi yaifupi kwambiri zitha kupezeka pogwiritsa ntchito spectrum analyzer ngati mita, koma chipangizochi ndi chokwera mtengo kwambiri ndipo kugula kwake chifukwa cha imodzi kapena ziwiri zosowa za mlongoti sikungatheke. Ngati kuli kofunikira, mutha kukhazikitsa dishi la satellite popanda zida zilizonse. Kuti muchite izi, wolandila satana ndi TV (laputopu yokhala ndi gawo la TV) amayikidwa pafupi ndi mbaleyo, ndipo chizindikiro cholandilidwa chimayang’aniridwa pamlingo wa pulogalamu yokhazikitsira wolandila. Panthawi imodzimodziyo, ndithudi, sizingatheke kukwaniritsa khalidwe lapamwamba kwambiri, koma njira iyi ndi yoyenera kugwiritsidwa ntchito kunyumba.
