Chii chinonzi Satellite?

Nheyo dzepamusoro pamusoro peSatellite

Basic Questions pamusoro peSatellites

Ma satelliti anomuka sei? Satellite radio inoshuwaridzana inokonzerwa nekutsvakurudza munharaunda yekutaurirana, kuitira kuti iwedzere kuwedzerwa kukuru kwekushanda kwepamusoro pane mari yakaderera yakakwana.

Mamwe mazano anopiwa nema satellites? Mu satellite telecommunication systems, muzvikwata zvemarefu, vanogonawo kuunganidza kana kuparadzira zviratidzo kubva kunzvimbo dzakasiyana-siyana pane kutumira kubva pane imwe nzvimbo kuenda kune imwe.

Chii chinonzi satellite uye chinoshanda sei? Icho chiitiko chemagetsi chinowanikwa munzvimbo, inogamuchira zviratidzo zvinowanikwa pasi, zvinowedzera uye zvinovatumira kudzokera pasi. Uye inoshanda nokuti rhidhiyo yemumhanzi "A" inounza chiratidzo chinogamuchirwa ne satellite. Shanduro yacho inoikudziridza uye inoidzorera pakarepo. Iyo ham radio operator "B" inogamuchira iyo uye inopindura nayo. Saka tanga kutaurirana kwepabonde.

Ndeapi maitiro emasetelliti akawanda anoshandiswa? Zvinenge zvese ma satellites anoshandiswa nhasi nekuda kwekutaurirana nemakambani emakambani ari GEO. Zvinonyanya kushandiswa kwemasateteni aya ndezvokuti-kusvika-multipoint uye pfungwa-kusvika-pfupa inotumira.

Zvimwe zvinobatsira zvekushandisa mashizha ane mashizha (MEO) Ma satellites emidenga yepasi pepanyika anotenderera ari pakakwirira pakati pe10075 nemakiromita 20150 Kusiyana neGeo (Geosynchronous Earth Orbit) nzvimbo yavo yakatarisana nepamusoro pepamusoro haisati yagadziriswa. Kuva panzvimbo yakaderera, nhamba yakawanda yetikateteri inodiwa kuti inotarisirwa pasi rose, asi latency inopera zvishoma.

Kuenzanisa kwemasetelliti nechinangwa chavo kana pasi pekucherechedza satellites. Meteorological satellites. Navigation satellites. Telecommunication satellites. Ma satellite ehondo uye vasori. Ham radio satellites.

Basa guru rekutengesa terevhizheni Itai kuti zviratidzo zvinogamuchirwa zvigadziriswe zvekudzorerazve pasi. Uyewo nekushandura nguva dzinowanikwa mazita ekutakura kudzivirira zvinetso zvinopindira

Zvimwe zvekuvakwa kwetaneti Nhare yacho inosanganisira mubhadharo uye nzvimbo. Iyo payload inosanganisira kugamuchira uye kutumira antenna, uye yemagetsi ehurumende inotsigira kutapurirwa kwemashoko anotakura zviratidzo. Nzvimbo yacho inoumbwa nehutsika dzose dzinobvumira mubhadharo kuti uite.

A satellite is complex system consisting of several smaller systems ... Zvirongwa Zvokudzora Control Points system inochengetedza mutungamiri muma satellites nguva dzose. Nzira yacho inoshandisa zvivharo (semaziso), saka antenna satellite "inoona" iyo iri kureva. Shanduro inoita kuti masayenzi ekucherechedza awane yakanyatsogadziriswa shanduro pane shanduro yekutaurirana. Mutemo uye Dhiyabhorosi Subsystem Maitiro ekudzora ekugadziriswa kwemashoko uye mirairo ndeaya anobata mabasa ose echadenga (brain brain). Kukurukurirana Subsystem Inyanzvi yekutaurirana ine mumiririri, anogamuchira, uye antennas akawanda kuti adzorere mharidzo pakati peti satellite uye pasi. Kudyiswa kwevhu kunoshandisa iyo kutumira mazano ekushanda kumakombiyuta epa satellite. Iyi sarudzo inotumirawo mifananidzo uye nedzimwe nhepfenyuro yakatorwa necheteretta kumashandisi pasi pano. Simba rekushandisa Sendika dzose dzinoshanda dzinoda simba kuti dzishande. Zuva rinopa kuti simba kune mashetera mazhinji anotenderera mumativi ose pasi. Iyi sarudzo inoshandisa magetsi ezuva kuti iite magetsi kubva kunezuva, mabhatiri kuti ichengetedze simba, uye ichigovera iyo kune zvishandiso munzvimbo yose. Basa rekubhadhara Payload ndiro iyo midziyo ye satellite inoda kuita basa rayo. Izvo zvakasiyana pamusangano mumwe nomumwe. Shanduro inoshandiswa nekutaurirana inoda mazhenesheni makuru ekutumira kutumira TV kana kuti Telefoni. Shanduro yekutora mapepa epasi inoda kamera ye digital kuti inotora mifananidzo yePasi. Shanduro yekutsvakurudza yesayenzi inoda teresikopu uye zvifananidzo zvekunyorera kutora maonero eredzi nemamwe mapuraneti.

Nguva yemberi mune kukura kwemasetelliti Kubva kwekuvandudzwa kwemasetellitete kunotarisirwa, izvo zvichave nezvine sampler yekugadzirisa midziyo inowanikwa mu satellite pachayo uye ichavandudza zviratidzo zvekutakura zvakare. Inter-satellite optical links, iyo inogona kuderedza nguva yekuparidzira pakati pezvikwata apo ma satellite akawanda anopindira. Kushandiswa kwemafirimu akakwirira (30 / 20 Ghz uye 50 / 40 Ghz.); Parizvino, izvi zvinokonzera zvinetso zvakanyanya zvekudzivirira, kunyanya nemhaka yemvura.


The Anatomy of Satellite:

Solar Arrays Solar arrays zvivako zvakakura zvinoumbwa nezviuru zvemasero mashoma ezuva. Sero rimwe nerimwe rinobudisa magetsi kubva kunezuva. Apo ose aya masero akabatanidzwa pamwe chete, anoumba simba rakawanda rinozoshandura pane zvigadzirwa zvepa satellite uye kubudisa mabheti e sataneti.

Blanquet Inopisa Iyo yefuti yehutsi inoumba chikamu chetsika yekudzivirira pasi. Girazi rinoumbwa nemucheka wakaisvonaka unobatanidza rese satellite, uye unoita mabasa anotevera: inochengetedza satana ichidziya kubva kunotonhora uye kunotonhora mumhepo. Ma satellites anoratidzirwa kunotonhora uye kutonhora kunotyisa (-120 kusvika + 180). Pasina bhandi yehutu, ichocho chinonyangadza chemagetsi chinogona kuparadzwa.

Batery Bhati iri chikamu chemasimba epasi. Chengetedza simba remagetsi rakagadzirwa nemagetsi ezuva kuitira kuti rigone kushandiswa nezvose zvemagetsi yemichina ye satellite.

Bus Structures Chikamu chinokosha chetaneti ndechekugadzirisa pamwe chete. Chimiro chebhazi chinowanzoitwa chakajeka uye chakanyanya kusagadzikana zvinhu chichave chakasimba zvakakwana kutsigira zvimwe zvidimbu, asi kwete zvakanyanya kuitira kuti satana irege kukwidziridzwa mumutsetse.

Nyeredzi nyeredzi Vateveri venyeredzi ndivo chikamu chekutonga pasi. Izvo zvidiki zvidhesiko zvinoda nzvimbo uye kuverenga nzvimbo yeredzi. Ma satellites anoshandisa nzvimbo yenyeredzi kufamba, sezvatinoita pasi pano.

Reaction wheels Izvo zvinoita mavhiri acho ndeyewo chikamu chekutonga pasi. Izvi zvinoshandura shanduro nenzira dzakasiyana. Simba rayo rinokonzera satellite kuti iende uye inotarisa munyaya dzakananga.

I / O Processor Iko inowanikwa-yakabuda purogiramu chikamu che data uye murairo wechirongwa. vanodzora kuyerera kwedheta mukati uye kubva kumakombiyuta anomhanya.

Omni Antennas Iko omni antenna chikamu chemashoko ekukurukurirana. Iyo inoshandiswa kutumira mameseji pakati pekutarisa satara uye pasi.

Makombiyuta anomhanya Iyo kombiyuta inobhururuka inhengo ye data uye mirayiridzo yehutano. Iyi iropi hwetabhenekeri inotarisira basa rose pama satellites.

Transmitter / receiver Iyo inotumira / inogamuchirwa chikamu chemuviri wechirangaridzo. Kana ma satellites achida kutumira fomu yevhu, mutumira anotamisa dhidhiyo yemufananidzo muchiratidzo chinogona kubudiswa pasi. Apo injini dzinotumira mutemo kune satellite, mutambi wemapuraneti anotora chiratidzo uye anotumira kuchinja mumashoko ayo kakombiyuta inonzi satellite inogona kunzwisisa.

Chikamu chenyika Iyo inosanganisira nzvimbo dzose dzepasi; idzi dzinowanzobatanidzwa kumushandi wekupedzisira kuburikidza nehutano hwepasi, kana pane zviteshi zviduku, zvakanamana zvakananga kumidziyo yomugumi yekupedzisira.
