Kugena imirongo, azimuth hamwe nuburebure bwibiryo bya satelite

Kwerekana icyogajuru “isahani” kuri satelite ni inzira yoroshye, ariko bisaba ko umuntu agira byibura ubumenyi bwibanze mugukorana nibikoresho bya antene. Mubihe byinshi, birasabwa guha inzira umuhanga winzobere, ariko niba kubwimpamvu iyo ari yo yose (ikintu gifite umutekano, ahantu kure, nibindi) bidashoboka gukoresha serivisi ze, noneho urashobora kugerageza guhindura antenne wenyine .
Gushiraho impande ya azimuth nuburebure bwibiryo bya satelite ukoresheje gahunda ya SAA [/ caption]

Nigute washyiraho impagarike yuburebure ku isahani ya satelite na azimuth kuri satelite

Mbere yo gukomeza hamwe nubuyobozi butaziguye kuri satelite, birakenewe gushakisha no kwandika indangagaciro zibipimo bisabwa. .

1. Ikibanza cya Antenna kirahuza . Urashobora kumenya guhuza muburyo bumwe muburyo butandukanye – ukoresheje GPS igendanwa, ukoresheje porogaramu nka GoogleMaps nibindi bisa, ukoresheje ikarita ya geografiya cyangwa mubundi buryo buboneka. Niba ufite terefone kandi ukaba uri mukarere kegeranye numuyoboro wa selire, kugena imirongo ntigomba kugorana.
2. Uburebure na azimuth kuri satelite . Umwanya wingenzi cyane muburyo bwose bwo guhuza antene. Niba aya makuru atazwi neza muburyo bwambere, hanyuma kugirango ayimenye, birasabwa gukoresha imwe muri serivise za interineti, kurugero, kubara kubuntu kumurongo “Satcalc”.

Kubara azimuth nuburebure bwo kwishyiriraho ibiryo bya satelite urashobora kubisanga kuri https://www.satcalc.ru/angle.php?s=&s_min=&s_sec=&d=&d_min=&d_sec=&d_0=140e&n_0=140e

Urugero rwo kubara icyerekezo kuri satelite ukoresheje calculatrice

Reba inzira yo kumenya icyerekezo cya antenne yerekana ukoresheje urugero rwa satelite Express AM3 mumujyi wa Vladivostok. Tumenye guhuza ibikorwa bya antenna yo gushiraho nuburyo ubwo aribwo bwose buboneka. Umujyi wa Vladivostok, abahuzabikorwa bazagira indangagaciro zikurikira – uburebure: 43 ° 06′20 ″, uburebure: 131 ° 52′24 ″ E. Jya kurupapuro rwo kubara kumurongo.
Satkalk [/ caption] Mu idirishya rifungura, kanda kumurongo “Kubara azimuti nuburebure”.
Kimwe mu byiza byiyi calculatrice kumurongo nigikorwa cyo guhita ugena imirongo ihuriweho nizina ryumudugudu, ukurikije geolokisiyo ya terefone cyangwa na aderesi ya IP yibikoresho (terefone, mudasobwa igendanwa, PC) urubuga rwavuyemo kugerwaho. Injira imirongo.
Mu idirishya ridasanzwe, hitamo icyogajuru kizakorerwa ubuyobozi, muritwe Express AM3.
Kanda ahanditse pop-up “Kubara Azimuth n’Uburebure”.
Twabonye amakuru asabwa.
Hariho ikindi kintu kimwe mubice byamakuru – “Guhinduranya kuzenguruka”, iyi ni ikintu cyingenzi, byinshi kubyerekeye bizasobanurwa mugice cyo kwishyiriraho antene.

Guhitamo aho ushyira

Mugihe ushyira antenne, ugomba kwibanda kubintu bitatu byingenzi.

1. Ahantu hafunguye cyane mu cyerekezo cya satelite , nibyiza ko umurongo ugaragara, utabujijwe ninyubako, ibiti, imisozi nyaburanga. . _
2. Kwizerwa kwa antenne . Nkuko bisanzwe, indorerwamo yibiryo bya satelite, bitewe nuburyo bwo gushushanya, ifite umuyaga mwinshi kandi, niba bidafunzwe neza, bizahungabana biturutse kumuyaga.
3. Komeza intera kuva antenne kugeza kuri satelite yakira mugihe gito gishoboka . Ikigaragara ni uko insinga iyo ari yo yose itangiza coefficient yayo – ni ukuvuga, igabanya urwego rwibimenyetso byingirakamaro. Ni muri urwo rwego, nubwo ukoresha umugozi wo mu rwego rwohejuru, ntibisabwa kwimura antenne kure yakira kuri metero zirenga 20-25.

Ahantu hatoranijwe hagomba kandi gutanga ubushobozi bwo kuzenguruka indorerwamo ya antenne kuri dogere 10-14 uhereye kuri azimuth. Niba hari inzitizi karemano (artificiel) mu cyerekezo cya satelite intera ntoya, urashobora kugerageza kumenya urugero rwingaruka zishobora kuba kumiterere yakirwa.
Kubara, birakenewe kumenya hafi intera yikintu nuburebure bwacyo (urugero, mugereranije uburebure bwibintu byegeranye nuburebure bwabyo bizwi), hanyuma ukoresheje kubara trigonometric cyangwa serivisi iyo ari yo yose ya interineti, kubara inguni y’uburebure ku kintu. Niba agaciro kabonetse katarenze agaciro k’uburebure (hejuru), noneho ntakintu nakimwe cyo guhangayika, bitabaye ibyo ukeneye guhitamo ahandi hantu kugirango ushyire antene cyangwa ukoreshe inkunga kugirango wongere uburebure.

Kugena imirongo yaho uherereye kugirango ushyireho icyogajuru – aya makuru arakenewe kugirango ubare azimuth nuburebure bwibiryo bya satelite ukoresheje calculatrice cyangwa software idasanzwe:

Gushiraho ibikoresho bya antenne

Igikorwa cyo gushiraho antene gitangirana ninteko yacyo. Mugihe cyo guterana, ugomba kwibanda kubyifuzo byabashinzwe. Nibisanzwe, antenne izana amabwiriza arambuye yo kuyateranya, yerekana ibipimo nyamukuru. .
_ indorerwamo ya antenne mu ndege ihagaritse kandi itambitse ntabwo ikomera inzira yose. Kwishyiriraho uhindura bikwiye amagambo yihariye. Ihindura ryashyizwe kumurongo wa antenne yuzuye kandi ikazunguruka ku gaciro kangana yabonetse muri gahunda ya Satcalc murwego rwo kubara azimuth nuburebure. Agaciro muri LNB Kuzenguruka inkingi yerekana ko LNB igomba kuzunguruka dogere 46 kuruhande rwisaha uhereye kumurongo. Kugirango byoroherezwe gushiraho inguni, ibimenyetso bikoreshwa imbere yimpinduramatwara yerekana “umwanya wa Zeru” nubunini buringaniye. Intambwe yanyuma mugushiraho antene ni uguhuza umugozi na label ihindura.

Antenna

Ibyokurya bya satelite bigabanijwemo “Direct Focus” na “Offset”. Urashobora kubitandukanya byombi mugusoma inyandiko zometseho, kandi muburyo bugaragara – butaziguye-bwibanze bufite ibizunguruka, indorerwamo ya antenne ya offset ifite ishusho ya ellipse (irambuye cyane yerekeza mu cyerekezo cya axe ihagaritse). Buri antenne ifite ibimenyetso byayo byerekana – indege yindorerwamo ya antenne yibanze-yerekeza kuri satelite mugihe cyo guhuza ukurikije amakuru yo hejuru. Antenna ya offset ifite ikindi kintu cyongeweho – “offset angle”, agaciro kayo murashobora kugisanga mubyangombwa bya antenne.Iyo ushyizeho antenne ya offset, umwanya ukenewe windege yindorerwamo ubarwa na formula – ƛp = ƛm – ƛs. Aho ƛp ni umwanya ukenewe wa offset antenna indorerwamo ugereranije na horizontal, ƛm ni impagarike yuburebure ibarwa nuburyo bwa software, ƛs ni inguni ya offset igaragara muri pasiporo ya antenna. Bibaho ko nyuma yo kubara, agaciro kabonetse hamwe nikimenyetso cyo gukuramo, bivuze ko indorerwamo ya antenne ya offset igomba kugororwa nigiciro cyimpande zabonetse.
Inguni ya azimuth nuburebure bwibiryo bya satelite irashobora kubarwa idafite calculatrice – binyuze mumikorere:

“Shakisha” icyogajuru

Kwerekana neza antene kuri satelite birashobora kugabanywamo ibice bibiri. Ku cyiciro cya mbere, hahinduwe “bikabije”, ku cya kabiri birarangiye. Guhuza neza bivuga kwerekana antenne kuri satelite muri azimuth no murwego rwo hejuru. Kugirango ukore ibi, indorerwamo ya antenne yazamuwe nuburinganire bwabazwe (ukurikije inguni ya offset ya antene ubwayo). Kuri iki cyiciro, goniometero ifatanye nindege ya antenna izaza ikenewe.
Ubuyobozi bwa Azimuth bukorwa hakoreshejwe compas. Hariho kandi uburyo bwo kwerekana “ukurikije izuba”, butanga ibisubizo byiza, ariko mubikorwa abantu bake barabikoresha bitewe nubushobozi buke bwabyo (igicu, ntibishoboka buri gihe kubara umwanya nyawo wizuba mugihe gikwiye , n’ibindi). Ihinduka rya nyuma rikorwa ushizemo metero idasanzwe – “SatFinder” mu cyuho cya kabili hagati yimihindagurikire niyakira. Ibipimo birashobora kuba imvugo yoroshye kandi igoye cyane. Ibyo ari byo byose, umwe muri bo akora imikorere yazo.
Kugirango uhindure neza, fungura antenne hanyuma uyizenguruke buhoro muri azimuth, ugerageze kutarenza umuvuduko wa dogere 1 kumasegonda. Nyuma yo gufata ibimenyetso, uburyo bwo guhinduranya buto (ibumoso / iburyo) bugomba kugera kurwego rwo hejuru rwibimenyetso no gukosora antene. Niba ikimenyetso kigaragaye, ariko mubyukuri ntigire icyo gihindura ku ndorerwamo cyangwa ubuziranenge budahungabana, birasabwa guhinduranya antenne kuri dogere 1-2 ukurikije umurongo uhagaze ugereranije nu mpande ndende. Ibisubizo byiza mugihe gito gishoboka birashobora kugerwaho ukoresheje isesengura rya spekiteri nka metero, ariko iki gikoresho gihenze cyane kandi kugura kubwikibazo kimwe cyangwa bibiri bidasanzwe byo guhuza antenne ntibishoboka. Niba ari nkenerwa rwose, urashobora gushiraho icyogajuru kitagira ibikoresho na gato. Kugirango ukore ibi, imashini ya satelite hamwe na TV (mudasobwa igendanwa ifite module ya TV) ishyirwa hafi yisahani ubwayo, kandi ibimenyetso byakiriwe bikurikiranwa ku gipimo cya porogaramu yakiriye wenyine. Igihe kimwe, byanze bikunze, ntibishoboka kugera ku rwego rwo hejuru rushoboka, ariko ubu buryo burakwiriye gukoreshwa murugo.
