Minimum Notions of Models uye Zvirongwa

Marudzi ema satellites - History of Satellites Kuti vawane huwandu hukuru mukushanda kwepamusoro nemari yakaderera kunogona kuwanikwa, tsvakurudzo munharaunda yekutaurirana inomuka. Nokudaro pfungwa yekutengesa materetetiti yakabuda nguva pfupi Hondo Yenyika II ichangopera, nekuda kwekubatanidzwa kwemhando mbiri dzakasiyana-siyana (misoro uye microwaves). The nzvimbo zera yakatanga muna 1957 pamwe pakuparurwa rokutanga chakagadzirwa Satellite Sputnik I of FSU, yakanga akatakura redhiyo bhikoni iyo chaibwinya chiratidzo panguva frequencies 20 uye 40 Mhz. iyi chiratidzo chinogona kugamuchirwa nevakagamuchiri nyore munyika yose vachiita kuedza kwokutanga kwekutumira uye kugamuchira zviratidzo kubva munzvimbo.

Unhu hwema satellites Chinyanya kukosha ndechekusiyana kwemasangano anopiwa neTable telecommunication systems, kuparidzirwa kwakakwana kwemasetelliti kunoshandiswa kusimbisa mararamiro akareba kure. Chimwe chimiro chemasetelliti ndechekuti vane simba rokuunganidza kana kuparadzira zviratidzo kubva kunzvimbo dzakasiyana-siyana pane kutumira kubva pane imwe nzvimbo kuenda kune imwe.

Chii chinonzi satellite? Icho chiitiko chemagetsi chinowanikwa munzvimbo, inogamuchira zviratidzo zvinowanikwa pasi, zvinowedzera uye zvinovatumira kudzokera pasi. A satellite chinhu chipi nechipi chinotenderera kumativi ose kana chinotenderera chimwe chinhu. Semuenzaniso, mwedzi inotenderera pasi, uye nyika inotenderera yezuva.

Shanduro inoshanda sei? Rhidhiyo yemumhanzi "A" inounza chiratidzo chinogamuchirwa nesataneti. Shanduro yacho inoikudziridza uye inoidzorera pakarepo. Iyo ham radio operator "B" inogamuchira iyo uye inopindura nayo. Saka tanga kutaurirana kwepabonde. Kutaurirana satellites kuita seRelay Stations munzvimbo. Zvinoshandiswa kutumira mameseki kubva kune imwe nzvimbo yenyika kune imwe. Iyi mharidzo inogona kunge iri foni, firimu yeTV, kana kunyange kuIndaneti. Kukurukurirana masetelliti akaita seEchoStar ari mumugumo we geosynchronous (geo = pasi + synchronous = kufamba kamwe chete). Izvozvo zvinoreva kuti satara inoramba iripo pane imwe nzvimbo pasi. Nzvimbo iri pasi pano inogona "kuona" inonzi satellite footprint.


Aina dzeSatellites:

Nenzira yayo:

Ø Satellites of geostationary orbit. Kana muchadenga riri Equatorial mundege Nyika, nechokure kweinenge 36000Km (yakaenzana 5,6 iri nharaunda yenyika), uye somugumisiro, zviri orbital nguva chaizvo kuenzana kureva nguva vachishandisa kutenderera kwenyika (, 23 H, 56 Nha uye 4s), rinozivikanwa sidereal zuva, ipapo tinoti muchadenga ndiye geostationary Satellite uye kumhanya kuburikidza muchadenga iri geostationary Satellite. Aya ndiwo mavambo ekukurukurirana kweSatellite, uye zvinenge zvese ma satellites anoshandiswa mazuva ano ekukurukurirana nemakambani emakambani ari GEO. Zvinonyanya kushandiswa kwemasateteni aya ndezvokuti-kusvika-multipoint uye pfungwa-kusvika-pfupa inotumira.

Ø Kureba kwemasetelliti (LEO).Leo satellites dziri munzvimbo yakaderera kutenderera, pamusoro 1.500? Km paavhareji, asi unogona kuva pakati 200 uye 2000 km ari orbital nguva vari pakati 90 uye 120 maminitsi. Izvi kutenderera vanotambura zvaishandiswa mumazuva mabikirwo Satellite kukurukurirana okutanga somumwe matanho kufukidza kusvika pakupedzisira chinangwa panguva, raiva geostationary Satellite, apo asi pakanga kukwana zvinoreva vabudirire kanda simba kunodiwa kuti aise saratani mumuguta we360000 wekukwirirana kwakananga kusvika kumagetsi ekudzivirira.

Nechinangwa chayo:

Ø Nyika yekucherechedza satellites.

Ø Meteorological satellites.

Ø Kutarisa satellites.

Ø Telecommunication satellites.

Ø Masatellite emauto uye vasori.

Ø Ham radio satellites.


Kubatsirwa uye Kukanganisika

Kubatsirwa

Ø Kuparidzirwa kwepamusoro kwenzvimbo dzakawanda, nekusiyana nemasikirwo enyika, ekugadzirisa kushanda.

Ø Kusakwanisa kuzvimiririra pamabhara uye zvipingamupinyi zvepanyama zvakadai sezvikomo, nezvimwewo.

payakaipira

Ø Nhepfenyuro dzemazuva ano dzinofanirwa kuparidzirwa kunonoka, dzinokonzerwa nemvura, chando uye sunspots dzinosanganisira nzvimbo dzepasi, dzinotambura neredhiyo, microwave uye kukanganisa kwenhandare.

Ø High cost.

Ø Upenyu nguva.

Ø Dambudziko rezvemitemo.


Satellite Iyo inomirira nheyo yepamusoro uye inosungirirwa yehutano kuburikidza neboka rezvikwata zvenguva imwe chete zvinopfuura. Nenzira iyi, inogona kuonekwa sechinhu chinonyanyisa chetaneti. Nheyo huru dze saterevhizheni saterendi ndeyotevera: Ø Itai kuti zviratidzo zvinogamuchirwa zvinogamuchirwa zvekudzorerazve pasi. Ø Kuchinja kwemafambiro emitambo yekutakura kunzvenga zvinetso zvekuvhiringidza Ø Dhiabhorosi ine mubhadharo uye chikwata. Ø Mubhadharo unosanganisira kugamuchira uye kutumira antenna, uye yemidziyo yemagetsi inotsigira kutumidzwa kwemashoko ekutakura mashoko. Ø Nzvimbo yacho inosanganisira zvose zvinyorwa zvinoita kuti mubhadharo uite.
