Mawallafi na tauraron dan adam

Ƙananan Bayanai game da samfurori da zane

Irinin tauraron dan adam - Tarihi na Satellites Domin samun ƙarin haɓaka a cikin karfin aiki tare da farashi mafi ƙasƙanci, bincike a wurin sadarwa ya taso. Don haka ne ra'ayin tallan tauraron dan adam ya bayyana jim kadan bayan yakin duniya na biyu, saboda haɗuwa da fasaha guda biyu (missiles da microwaves). A sarari shekaru fara a 1957 tare da ƙaddamar da farko wucin gadi da tauraron dan adam Sputnik na daga cikin FSU, wanda aka ɗauke da rediyo mashirya wanda ake jefarwa wata sigina a mitoci 20 da 40 MHz. wannan siginar za a iya karɓa ta hanyar masu karɓa mai sauƙi a ko'ina cikin duniya yin gwajin farko na watsawa da karɓar sakonni daga sarari.

Halaye na tauraron dan adam Siffar da ta fi dacewa ita ce rarrabuwa na hidimomin da aka bayar ta hanyar sadarwa ta hanyar tarho ta hanyar sadarwa, ana amfani da adadin sararin samaniya don kafa tsattsauran nisa. Wani nau'i na tauraron dan adam shine cewa suna da ikon tarawa ko yada sigina daga ko zuwa wurare dabam dabam maimakon a aika daga wani aya zuwa wani.

Menene tauraron dan adam? Yana da na'urar lantarki wanda ke cikin sararin samaniya, yana karɓar sakonni da aka haifa a cikin ƙasa, yana ƙarfafa su kuma ya aika da su zuwa duniya. Wani tauraron dan adam shine duk wani abu wanda yake motsawa a kewaye ko yayi wa wani abu wasa. Alal misali, watã wata tauraron dan adam ne na duniya, kuma ƙasa tana tauraron tauraron rana.

Ta yaya aikin tauraron dan adam ke aiki? Rundunar rediyo ta "A" ta tura siginar da ta karɓa ta hanyar tauraron dan adam. Sararin tauraron dan adam ya fadada shi kuma ya sake dawo da shi nan da nan. Kamfanin radiyo mai suna "B" yana karɓar shi kuma ya amsa. Don haka fara sadarwa ta tauraron dan adam. Satellite sadarwa suna aiki a matsayin Relay Stations a sarari. Ana amfani da su don aika saƙonni daga wani ɓangare na duniya zuwa wani. Wadannan saƙonni zasu iya zama kiran wayar, hotuna hotuna, ko ma Intanit. Sararin tauraron sadarwa kamar EchoStar suna cikin haɗari na geosynchronous (geo = duniya + synchronous = motsi a daidai lokacin). Wannan yana nufin cewa tauraron dan adam ya kasance a kowane wuri a ƙasa. Yankin a duniya wanda zai iya "Dubi" ana kiransa layin saitunan tauraron dan adam.

Ø Satellites na hawan geostationary orbit. Lokacin da sararin samaniya ne a Equatorial jirgin sama na duniya a nesa na kimanin 36000Km (daidai 5,6 da radius daga ƙasa), kuma saboda haka, da orbital lokaci ne daidai da daidai lokacin da juyawar duniya (ie, 23 h, 56 min da 4s), da aka sani da sidereal rana, sa'an nan mu ce cewa kewayewa ne geostationary da tauraron dan adam da kuma guje, ta hanyar wannan kewayewa ne geostationary tauraron dan adam. Wadannan sune farkon mafita don sadarwa ta hanyar sadarwa, kuma kusan dukkanin tauraron dan adam da ake amfani dashi a yau don sadarwa ta hanyar kamfanoni na kamfanonin GEO ne.
