Broadband setiraiti Internet inowanikwa kune chero mugari wePasi chero kupi zvako papasi chiroto chiri kuitika zvishoma nezvishoma. Satellite internet yaimbodhura uye ichinonoka, asi zvave kuda kuchinja.
Ivo vari kuita mukuita kwechishuwo chirongwa nenzira yakanaka, kana kuti, mapurojekiti emakambani SpaceX, OneWeb. Uye zvakare, panguva dzakasiyana Facebook, Google uye mubatanidzwa wehurumende Roscosmos yakazivisa kusikwa kwetiweki yavo yeInternet satellite. Kune vakawanda, nyaya yacho haina kupfuura fungidzirowo zvadzo kana kuti matanho ekutanga ekugadzirwa kwesatellite.
Chii chakatoitwa?
SpaceX Elon Musk
Zvinhu zvakawanda. Nokudaro, SpaceX corporation yakaronga kuunza 4425 satellites muEarth orbit, zvino zvakasarudzwa kuwedzera nhamba yavo kusvika ku 12 000. Zvingave kuti izvi hazvisi zvose, asi boka racho richawedzerwa kusvika kune makumi ezviuru zvezviuru.
Mari yeprojekti inenge madhora mabhiriyoni gumi. Muna May gore rapera, kambani yaElon Musk yakatanga kupinda mumhepo. uchishandisa Falcon yekutanga mota. Masisitimu akati wandei akabva adzorwa kuti aedze zvakasiyana-siyana zvepurojekiti.
Vamwe vose vakasara vachishanda. Muna Mbudzi 2019, mamwe makumi matanhatu masetellite akatangwa. Uye zvadaro, muna Ndira wegore rino, kambani yakatanga mimwe michina makumi matanhatu, yakaunzwa ku orbit panzvimbo yakakwirira ye60 km pamusoro pePasi. Parizvino, masatelliti mazana matatu kubva paanofungidzirwa 60 290 akatangwa. 300 acho anoshanda sezvaanofanira kuita.
Mukutanga kwaKurume, nhau dzakabuda dzekuti SpaceX yaive ichivaka masatellite nekukurumidza kupfuura zvayaigona kuavhura. Zvino, kana iwe ukagovanisa huwandu hwemasetelliti akatangwa nenhamba yemwedzi yapfuura kubva masatellite ekutanga akatumirwa mu orbit, zvinoitika kuti paavhareji kambani inotumira 1,3 satellite pamwedzi.
Dambudziko nekutangwa nderekuti dzimwe ndege dzekutangisa mota dzinofanirwa kudzokororwa nekuda kwemamiriro ekunze, kukanganisa kwehunyanzvi uye mamwe matambudziko. Naizvozvo, akawanda ema satellite akatogadzirira, ari paPasi uye akamirira mumapapiro. Iyi haisi fungidziro, asi chirevo chepamutemo kubva kukambani. Zvekuti zvese zvichashanda sei, .
Musk: Starlink satellites ari kugadzirwa nekukurumidza kupfuura isu tinogona kuvatanga. Tinoda Starship kuti mari yekutangisa idzike

SpaceX inogona kunge iri yekutanga kambani yezvichadenga kugadzira akawanda orbiters kupfuura yaanogona kuvhura. Iyo SpaceX fekitori iri kushanda zvakanaka.
Nenzira, kare uye ikozvino nhamba yevazivi venyeredzi kubva kuRussian Federation uye kunze kwenyika vakapomera SpaceX kuti zviuru zvakawanda zvemasatelliti ari kutenderera pasirese zvichakanganisa kutarisa kwechadenga kana kuita kuti kuongorora kwakadaro kusagoneke. Asi SpaceX yakataura kuti kana ese satellite ave munzvimbo, anozove mashoma kuoneka. Munguva pfupi iri kutevera, vazivi venyeredzi havakwanisi kumisa chirongwa ichi. IInternet ichatanga kushanda mushure mekunge nhamba yemidziyo iri muorbit yadarika 800.
OneWeb
Kubudirira kweanokwikwidza SpaceX kune mwero, asi kukosha kweOneWeb purojekiti hakufanirwe kudzikiswa. Iyo kambani ichaunza anenge mazana matanhatu emasatelliti mu orbit, ayo achapa mukana kune Broadband Internet mune chero, kunyangwe kona iri kure kwazvo yepasi.
Wireless kutaurirana kuchawanikwa kwete kune isu chete pamusoro penyika, asiwo kune avo vari mundege.
Sekureva kwemukuru wekambani yeBritish, mugore nehafu ma satellite ese anofanirwa kuendeswa mu orbit. Ivo vanotangwa nerubatsiro rwekutanga opareta Arianespace, iyo, zvakare, yakapinda muchibvumirano neRoscosmos.
Maseneti matanhatu ekutanga eOneWeb akatumirwa mukutenderera muna Kukadzi gore rapfuura kubva kuKourou spaceport. Vasara makumi matatu nemana vakasvika muna Kukadzi wegore rino vachibva kuBaikonur.

Iye zvino OneWeb inoronga kutanga zvishandiso zvayo kamwechete pamwedzi - hongu, kwete imwe panguva, asi muboka. Kwemakore akati wandei ikozvino, kambani iyi yanga ichiedza kutaurirana mubatanidzwa neRussia mukuwedzera kune kutangwa kwema satellite neRoscosmos. Asi, zvinosuruvarisa, kune mamwe matambudziko pano kupfuura kubudirira - zvese maererano nekupa mafambiro uye maererano nemutemo mutemo wekutaurirana, izvo zviri "kwese." Iwo masevhisi ehungwaru haana kunyanya kufara nesarudzo iyi.
Vatsigiri vekambani iyi vaisanganisira SoftBank, Mhandara, Qualcomm, Airbus, Mexican Grupo Salinas, hurumende yeRwanda, pamwe nevamwe, saka hapana chikonzero chekunetseka nezveramangwana reOneWeb satellite network kunyangwe tichitarisa zvitsva zviri kuitika. mumunda wehupfumi.
Zvakadini nemutengo wekukurukurirana?
Parizvino, maverengero anozivikanwa chete maererano nemutengo, pasina markups kune vatengi. Munguva pfupi yapfuura, mumwe wevashandisi veViasat forum akaenzanisa (haisi mukwikwidzi kuStarlink kubva kuSpaceX uye OneWeb, pamwe nemamwe maviri akurukurwa pamusoro).
Akaverenga mutengo wegigabit imwe pasekondi kune akasiyana network (iyo unit yekuyera ndeye $ / GBps, sezvakaratidzwa paforamu).
Hezvino zvakaitika:
- $2,300,000 Viasat 2
- $700,000 Viasat 3
- $300,000 OneWeb chikamu chekutanga
- $25,000 Starlink
- $10,000 Starlink w/Starship
Pamusoro pezvo, akaverengerawo mutengo wekugadzira uye kutangisa masatellite emakambani aya muEarth orbit:
- Viasat 2 - $600 miriyoni.
- Viasat 3 - $700 miriyoni.
- OneWeb - $500 zviuru.
- Starlink - $500 zviuru.
Kazhinji, iyo Internet inowanikwa pachena yepasirese inofanirwa kuoneka mukati megore nehafu. Zvakanaka, mumakore 3-5, mapurojekiti ese ari maviri, StarLink neOneWeb, achasvika pakukwanisa kwavo kwakagadzirwa uye, pamwe, kuwedzera mamwe masatellite kumanetiweki avo. Mufaro wava pedyo, %usasrname%.
