I-Starlink yodlula uphawu lwe-satellite ye-10.000: le yindlela ekhangeleka ngayo ikroza

I-SpaceX igqithise isiganeko esibalulekileyo kwi-satellite constellation: ngoku ngaphezu 10.000 Starlink yasungulwa ukususela ngo-2018. Uphawu lwafikelelwa emva kokuba a ukuqaliswa kabini kweeyunithi ezingama-56 yenziwe ngosuku olunye.

Inkqubela phambili inxulumanisa imida yobugcisa kunye nokusebenza, kodwa ikwavula Imibuzo malunga nokuzinza kwe-orbital, ummiselo, kunye nokulinganiswa kwemizi-mvelisoKule migca ilandelayo sijonga kwakhona Amanani aphambili, iinkcukacha zendiza kunye nokulandelayo.

I-10.000 Starlink ephawulekayo

Ngo-Okthobha we-19, imisebenzi emibini ye-Starlink yenziwe, enye isuka ICape Canaveral (eFlorida) kunye nomnye ukusuka EVandenberg, eCalifornia, kunye neesathelayithi ezingama-28 kuphehlelelo ngalunye. Ngabo, inani lilonke liyenyuka ukuya 10.006 satélites ithunyelwe kwi-orbit, ngokobalo lwe-astrophysicist u-Jonathan McDowell.

I-booster yenqanaba lokuqala B1067 Walushiya kwakhona uphawu lwakhe: walugqiba olwakhe Indiza ye-31 kwaye walibuyisela iqonga ngokuma kwinqanawa engenabantu iA Shortfall yeGravitas eAtlantiki. Le rokethi iqokelele imisebenzi eyohlukeneyo njengoko CRS-22, Crew-3, Crew-4, Turksat 5B o I-Koreasat-6A, ukongeza kwiibhetshi ezininzi zeStarlink.

I-SpaceX iqinisekise impumelelo yamaphulo achongiweyo njenge Starlink 10-17 (Florida) y I-Starlink 11-19 (eCalifornia)Ngezi nqwelomoya zimbini zilandelelanayo, inkampani itywine umtsi oqinisekileyo ukuya kumanani amahlanu kwiqela layo le-broadband.

Sifike njani apha

El inkqubo yaqala ngo-2018 kunye neeprototypes UTintin A kunye noTintin BNgo-2019, ukuthunyelwa kokusebenza kwesizukulwana sokuqala kwaqala, Ngo-2020, i-beta yavulwa kwaye ngo-2021 inkonzo yayithengiswa ngokubanzi. kumazwe amaninzi.

Ukusukela ngoko, isantya siye sakhawuleza kuphela: ngaphakathi I-2019 yabona ukuhamba kokuqala ibhetshi yeesathelayithi ezingama-60, ngaphakathi Ngo-2024, uninzi lwemishini yavalwa. kwaye kwi 2025 loo mqulu wagqithwa ngomda ngaphambi kokuphela kuka-OktobhaI-cadence yokuqalisa ibe sisitshixo ekuxininiseni i-orbital mesh.

Bangaphi abasele bekwi-orbit kwaye kwenzeka ntoni kwabo basilelayo?

Ne Iisathelayithi ezingama-10.006 zaphehlelelwa, ezingama-8.860 zahlala kwi-orbit ukusukela nge-20 kaOkthobha., ngokwedatha ekhankanywe ngamajelo akhethekileyo. Umahluko ubandakanya iiyunithi eziye zadla umhlala-phantsi okanye zaphinda zangeniswa, nto leyo ebonisa ngokucacileyo umjikelo wohlaziyo oqhubekayo we-constellation.

Isathelayithi nganye yenzelwe a ubomi obuluncedo malunga neminyaka emihlanu kwaye, ekugqibeleni, ihlawulwe ngendlela elawulwayo ukunciphisa umngcipheko. Inethiwekhi ngokwayo ivuma ilahleko yemihla ngemihla ngenxa izaqhwithi zelanga, ukusilela okanye ukwaluphala; ekungeneni kwakhona, izixhobo zichithakala emoyeni.

Izicwangciso kunye nokukala: I-12.000 egunyazisiweyo kunye nexesha le-V3

I-SpaceX inemvume yokusasaza ukuya kuthi ga 12.000 satélites, kukhuphiswano ne Iprojekthi yeAmazon Kuiper, nangona ulwandiso lusetafileni olunokuthi luzise iqela leenkwenkwezi kumashumi amawaka ngaphezulu, kunye nogutyulo olomeleziweyo inqwelomoya, ulwandle neendawo ezikude.

Indaleko enkulu elandelayo iza kunye Starlink V3, inamandla ngakumbi kwaye iyakwazi. Ngenxa yobukhulu babo, ukuhanjiswa kwabo ngobuninzi kuya kuxhomekeka kwi Starship rocket, eya kuthatha i-Falcon 9 kule ntlawulo iqala ngo-2026, kunye neethagethi ze-bandwidth ezinokufikelela kwi-1 Gbps ngomsebenzisi ngamnye kwiimeko ezifanelekileyo.

Umngeni wokuzinza kwe-orbital

Ukukhula kwee-megaconstellations kuhambelana nenkulu ukugcwala kwe-orbitalI-ESA ilandelela amashumi amawaka ezinto kunye iqikelela ngaphezu kwe-1,2 yezigidi zamaqhekeza ubuncinane ubuncinane be-1 cm, ngokwaneleyo ukwenza umonakalo omkhulu, ingakumbi phakathi kwe-600 kunye ne-1.000 km ukuphakama.

Ngenxa yoko amandla e ulawulo lwetrafikhi kwindawo, kunye nemimiselo yokunciphisa i-deorbiting, ukulungelelaniswa phakathi kweenkwenkwezi, kunye nobuchwepheshe bokunciphisa obugcina ukhuseleko ngaphandle kokucothisa ukwanda kweenkonzo zesathelayithi.

Ne Starlink 10.000 amanqaku sele egqithile enkosi ngokuphehlelelwa kabini kunye nokuphinda kusetyenziswe okuphezulu kweFalcon 9, ikroza liyazomeleza ukugubungela ihlabathi njengoko ijongene nokutsiba okulandelayo ngeV3 kunye neStarshipUmceli mngeni omkhulu iya kuba kukugcina olu hlumo phantsi kwemithetho ecacileyo nesebenzayo enciphisa umngcipheko kwindawo enabantu abaninzi.

I-Starlink ikhawulezisa umqondiso othe ngqo ukuya kwiselfowuni: i-spectrum, izivumelwano, kunye nemephu yendlela

Ndingumntu othanda itekhnoloji ojike umdla wakhe we "geek" waba ngumsebenzi. Ndichithe ngaphezulu kweminyaka eli-10 yobomi bam ndisebenzisa itekhnoloji yokusika kwaye ndikhenkceza ngazo zonke iintlobo zeenkqubo ngenxa yokufuna ukwazi okumsulwa. Ngoku ndiqeqeshelwe ubugcisa bekhompyutha nakwimidlalo yevidiyo. Oku kungenxa yokuba ngaphezu kweminyaka emi-5 ndibhalela iiwebhusayithi ezahlukeneyo kwitekhnoloji kunye nemidlalo yevidiyo, ndisenza amanqaku afuna ukukunika ulwazi oludingayo ngolwimi oluqondakalayo kuye wonke umntu.

Ukuba unayo nayiphi na imibuzo, ulwazi lwam lusuka kuyo yonke into enxulumene nenkqubo yokusebenza yeWindows kunye ne-Android yeefowuni eziphathwayo. Kwaye ukuzinikela kwam kukuwe, ndihlala ndikulungele ukuchitha imizuzu embalwa kwaye ndikuncede usombulule nayiphi na imibuzo onokuba nayo kweli lizwe le-intanethi.
