I-Amazon Imemezela I-Kuiper Antenna Design for Space Internet Constellation Project
Ngokwemibiko yabezindaba yakwamanye amazwe, ngoDisemba 16 ngesikhathi sendawo, i-Amazon yamemezela ukwakheka kwe-antenna yamakhasimende ayo ukuze afinyelele iphrojekthi yenkampani enkulu ye-satellite ye-Kuiper, ehlose ukuhlinzeka nge-inthanethi ye-broadband evela emkhathini. I-antenna ithatha ukwakheka kwamalungu afanayo ngezigaba futhi iye yathuthukiswa futhi yahlolwa kule nkwindla.I-Amazon ithe ithiyo ingamayintshi angu-12 kuphela ububanzi, incane futhi ilula kunomklamo ongokwesiko othi. Ukuhlola kubonisa ukuthi i-antenna ingahlinzeka ngokuphuma okuphezulu okufika ku-400Mbps. Le nkampani iphinde yaveza ukuthi le antenna ingasetshenziselwa ukudlulisa ividiyo ye-4K kusuka kumasathelayithi e-geosynchronous. I-Geosynchronous satellite umkhumbi-mkhathi otholakala endaweni engamakhilomitha angaba ngu-22000 (cishe amakhilomitha angu-32000) ngaphezu komhlaba.Nokho, isathelayithi ye-Amazon Kuiper izoba seduze nomhlaba. NgoJulayi kulo nyaka, i-Amazon ithole imvume ye-Federal Communications Commission (FCC) yase-United States ukuthi yethule iqembu lesathelayithi elakhiwe ngamasathelayithi angama-3236 ephrojekthi iKuiper. Ukuphakama kwendiza yomkhumbi-mkhathi kusuka ku-590 km kuya ku-630 km. Njengoba amasathelayithi amaningi kangaka aseduze nomhlaba, iphrojekthi i-Kuiper izothumela ukumbozwa kwe-inthanethi kwe-broadband ephansi kubasebenzisi ngabanye emhlabeni. Umgomo wayo ukuhlinzeka ngosizo ezindaweni ezikude nezifunda ezingakwazi ukufinyelela ku-inthanethi yendabuko enesivinini esikhulu.
I-Amazon ingenye yezinkampani eziningi ezigxile ekwethuleni umlaza omkhulu we-inthanethi we-inthanethi. Kuyaqapheleka ukuthi uhlelo lwe-SpaceX's Starlink nalo luhlose umgomo ofanayo. Lolu hlelo lwakhiwe amasathelayithi acishe abe ngu-12000 futhi luzohlinzeka nge-inthanethi ye-broadband kusuka kumjikelezo womhlaba ophansi ukuya omaphakathi. Njengamanje, i-SpaceX yethule cishe amasathelayithi e-Starlink ayi-1000 futhi yaqala nokuhlola kokuqala. I-Amazon ayikaqalisi noma yimaphi amasathelayithi, futhi ayizange idalule ukuthi hlobo luni lwamarokhethi lawa masathelayithi azokwethulwa ngawo.I-Amazon ithe ngokunciphisa usayizi wamatheminali abasebenzisi, banganciphisa izindleko zokukhiqiza ihadiwe futhi banciphise iphuzu lentengo amakhasimende akhetha joyina uhlelo. Inkampani ithi ingakwazi ukufeza i-miniaturization ngokuphakamisa kakhulu izakhiwo ze-antenna encane ndawonye.Ngokwezithombe zetheminali yomsebenzisi we-SpaceX ezikhishwe abahloli be-beta ku-reddit, i-antenna ye-Amazon engu-12 inch incane kakhulu kunothi lwe-Starlink. Kubikwa ukuthi ukuze kuhlolwe ihadiwe ye-SpaceX's Starlink, abahloli be-beta kufanele bakhokhe kuqala u-$499 wawo wonke amadivayisi, bese bakhokha enye i-$99 ngenyanga. I-Amazon ayizange idalule intengo yephrojekthi i-Kuiper, kodwa inkampani yathembisa ukutshala imali eyizigidi eziyizinkulungwane ezingu-10 kulo msebenzi.
Isingeniso:
Isiliva le-925, elaziwa nangokuthi isiliva elihle, liyisinqumo esidumile sokwenza ubucwebe obuhle nobuhlala njalo. Idume ngobuhlakani bayo, ukuqina, nokufinyeleleka kwayo,
Isingeniso:
I-925 sterling silver iyinto efunwa kakhulu embonini yobucwebe ngenxa yokuqina kwayo, ukubukeka kwayo okukhazimulayo, kanye nokuthengeka kwayo. Ukuqinisekisa
