Niki transponder ya satelite, imbonerahamwe yumurongo

Sisitemu / imiterere ya satelite / imiterere yemeza guhuza no
kohereza ibimenyetso bya satelite byitwa transponder. Igikoresho cyohereza ikimenyetso gisubiza icyakiriwe. Sisitemu nkiyi ituma bishoboka gutangaza umubare wibintu byinshi bitandukanye biva muri satelite iyo ari yo yose kandi bigatanga serivisi zitandukanye. Hariho ubwoko bubiri bwa transponders ya satelite: transponders regenerative transponders hamwe nigituba kigoramye.

Abafilisitiya bamenyereye guhamagara imirongo ya transponder ivugwa kuri satelite, nubwo, mubyukuri, iki ni igikoresho kivuga kuri iyi radiyo yihariye.

Impanuka ya transponders

Ubu bwoko bwa transponder bufata ibimenyetso bya microwave. Ihinduranya inshuro yikimenyetso cyo kwinjiza mumurongo wa RF hanyuma ikiyongera. Igikoresho nkiki gikwiranye no kugereranya ibimenyetso bya digitale.

Transponders

Ibikoresho nkibi nabyo bikora imirimo yose ya tronc tronc tronction, ariko muriki gihe habaho guhinduranya inshuro no kongera imbaraga zerekana ibimenyetso. Usibye iyi mirimo 2, transponder yo kugarura ikora inshuro nyinshi ya demodulation kimwe no kugarura ibimenyetso no guhindura. Transponder ikora imirimo 2. Bakira kandi bakongera kohereza ibimenyetso, mugihe sisitemu zigezweho zisukura cyane bishoboka kubera urusaku rutari rukenewe.

Ihame ry’imikorere

Transponder ya satelite ni urutonde rwibigize rwashyizwe kuri satelite, igenewe guhita yakira no kohereza ikimenyetso kuri radiyo runaka. Irasa na satelite igizwe na antene.

Icyogajuru icyo aricyo cyose gifite numubare runaka wa satelite isakaza umurongo wa radiyo. Bitewe no gutangiza ubu buryo bwo gutangaza amakuru, umubare w’imiyoboro ya satelite kuri satelite imwe wiyongereye bitewe n’ubunini, uhereye ku mwanya umwe wa orbital birashoboka gutangaza imiyoboro igera ku gihumbi. Ihame ryimikorere ya transponder ya satelite niyi ikurikira – ikimenyetso cya tereviziyo ya satelite, yibanda kuri antenne ya transpoder, kandi kubera imiterere yacyo isa, yororoka nkaho kuva mu ndorerwamo ikagera ku ntego runaka – isahani yakira uyikoresha. , yohereza ibimenyetso kubakira, ikabihindura muri TV isomeka. Ibice byingenzi bigize transponder ni:

• antenne yo kwakira ikimenyetso – igikoresho nyamukuru cyo kwakira ibimenyetso byerekanwe;
• imbaraga zongera imbaraga – zongerera imbaraga ibimenyetso byakiriwe kurwego ruhagije;
• duplexer (filteri yo gutandukanya inshuro)  – igikoresho cyagenewe gutunganya itumanaho rya radio duplex ukoresheje antenne imwe isanzwe yo kwakira no kohereza ikimenyetso;
• kugenzura gutunganya – guhitamo no guhindura ibimenyetso byinshyi.

Transponders kumiyoboro ya satelite yo kureba kubuntu TV ya satelite muri 2021

Hano hari imiyoboro ya tereviziyo ushobora kureba kubuntu, hariho imiyoboro ifunze nurufunguzo ruhamye rwa BISS. Imiyoboro muri BISS encryption irakingurwa kubuntu ukoresheje emulator yimbere. Muri ibyo bihe byombi, ugomba kuba ufite imbonerahamwe igezweho ya frequency na transponders hafi kugirango ushireho tereviziyo ya satelite. Imbonerahamwe yubu ya transponders itangwa hepfo, uburyo bwa code, inshuro nayo irasabwa, transponder ifunze cyangwa yubusa irerekanwa. Urutonde rwimiyoboro ya satelite na transponders ya 2021 kuri satelite Eutelsat 36B, 36.0E:

Gushiraho amakuru

Reka tuvuge ko twafashe icyemezo kuri satelite. Kurugero, iyi ni Eutelsat 36B, 36.0E. Birakenewe gushiraho ibiryo bya satelite no gufata ikimenyetso, kumenya ubwiza bwikimenyetso. .
_ _ _ Inkingi yambere ni “Frequency” – dushobora gufata inshuro zisabwa kuva kumeza ya transponders na frequency. Mu ntangiriro, ugomba gusobanukirwa nuburyo iyi frequency irimo. Dutwara muri ngombwa dukoresheje igenzura rya kure.
Ubwoko bwa polarisiyasi bushyirwa mu nkingi imwe (inyuguti iruhande rwayo). Uhagaritse cyangwa utambitse (“H”, “V”). Abakira bose bigezweho bashyigikira hafi yubwoko bwose bwa polarisiyasi. Inkingi ya kabiri ni “Umuvuduko / SR”. Amakuru yinjiye muriyi nkingi – SR (igipimo cyikimenyetso) na FEC (gukosora amakosa). SR – agaciro kangana nigipimo cyikimenyetso uwakiriye ashyigikiye. Ariko icyogajuru cya kijyambere cyakira gishyigikira ubwoko bwose bwibi bintu, bityo rero iyi parameter irashobora gusimbuka. FEC– mugihe ukoresheje icyogajuru kigezweho gishyiraho-agasanduku, iyi parameter nayo irashobora gusimbuka. Inkingi ya gatatu “Izina ry’Umuyoboro” nizina ryumuyoboro wa satelite, ikimenyetso cyacyo kiva kuri transponder runaka. Kurugero, izina ryumuyoboro wa TV cyangwa radio, cyangwa izina rya serivise ya interineti. Inkingi ya kane ni “BISS / ID”. Ubwoko bwa kodegisi no kuba ihari / idahari byerekanwa nuyu murima.
Muyandi magambo, niba hari ubwoko bwa kodegisi muri transponder, noneho iyi serivisi irishyuwe. Kugirango ushireho ibikoresho bya satelite mubyukuri bigezweho, ugomba kumenya indangagaciro eshatu – inshuro, ubwoko bwa polarisiyasi, ubwoko bwa kodegisi. Ni he nshobora kubona imirongo ya none na transponders kumiyoboro ya satelite? Ibigezweho muriki gihe (hagati ya 2021) hejuru no hepfo mumyandiko, niba ukeneye ibishya, noneho hariho amahitamo abiri. Kuva mubitabo byacapwe byifuzwa, cyangwa kuri enterineti. Niba uburyo bwa mbere bukwiye cyane, kurugero, kubaturage, noneho birakenewe kugenzura ko ikinyamakuru cyatinze bishoboka, kuko imiyoboro ya satelite ihindura imirongo na transponders buri gihe. Kuri interineti, birahagije gutwara muri icyo cyifuzo “imbonerahamwe ya transponders”.Kuramo imbonerahamwe

Satellite TV transponders kuva MTS

Inshuro na transponders za TV ya satelite kuva MTS . Umuyoboro wa MTS kuri satelite ABC-2:

Gushiraho imiyoboro ya TV kuri MTS TV birashobora gukorwa mu buryo bwikora cyangwa, niba ubishaka, ibi bikorwa nabiyandikishije muburyo bwintoki. Mugihe cyanyuma, ugomba gutwara mumashanyarazi wenyine. .
_

• Shyira antenne yatanzwe kurukuta rwinyubako kuburyo imitwe iri kumurongo ukenewe kuri transponder.
• Shyira clamp kugirango isahani iri ku mfuruka ya 30 ° kugera kuri horizontal.
• Azimuth ya tilte ya “antenna” igomba gushyirwaho kuri vertical kuri 1 °.
• Shira isahani kuri 137 °.
• Fungura TV hanyuma urebe ubwiza bwibimenyetso.
• Niba ubuziranenge busabwa budahari, birakenewe kuzunguruka antene kuri dogere 1 no kugenzura ubuziranenge bwibimenyetso kuri buri ntambwe.
• Niba warabonye “TV kuva MTS”, noneho imiyoboro ya TV igomba gushyirwaho mu buryo bwikora.
• Niba ukeneye guhuza TV wenyine, koresha amakuru ya transponder yatanzwe hejuru.

Amabwiriza arambuye yukuntu washyiraho ibiryo bya satelite kuva MTS.

Intangiriro

Mbere yo kugura ibikoresho bya TV bya satelite muri MTS, ugomba. Reba uburyo bushoboka bwo gushiraho ibikoresho. Kubwiyi ntego, birashoboka gukoresha progaramu ya terefone yubuntu ishobora gukururwa mububiko bwa App cyangwa Isoko ryimikino (https://play.google.com/store/apps/details?id=com.esys.satfinder&hl=en&gl = Amerika). Porogaramu yitwa “SatFinder”, nyuma yo kuyishyira kuri terefone yawe, bizashoboka kumenya satelite iboneka mukarere runaka.
Porogaramu igufasha kumenya neza aho satelite iherereye, kandi izakwereka uburyo washyira neza antene. [ibisobanuro id = “umugereka_3101” align = “aligncenter” ubugari = “660”]
Igice cyibikoresho bya MTS byo guhuza no gutangiza isakaza imiyoboro ya satelite [/ caption] Nyuma yo kwishyiriraho, ugomba kugenzura ko ntakintu kibangamira kwakira ibimenyetso. Ibiti, inyubako nizindi nzitizi bizagoreka cyane ibimenyetso. Kugirango ushyire ibikoresho bya satelite, ukeneye ibi bikurikira:

1. module cyangwa umugereka.
2. Ikarita ya SIM niba bikenewe.
3. Isahani.
4. Umubare w’amasahani.
5. Umugozi .
6. Guhindura.
7. Dysec.
8. Igikoresho cyo gushiraho.
9. Gucomeka guhuza umugozi na TV.
