Amazon najavljuje dizajn Kuiperove antene za projekt svemirske internet konstelacije

Prema izvješćima stranih medija, Amazon je 16. prosinca po lokalnom vremenu najavio dizajn antene svojih kupaca za pristup tvrtkinom nadolazećem velikom projektu satelitske konstelacije Kuiper, čiji je cilj osigurati pokrivenost širokopojasnim internetom iz svemira. Antena ima fazni dizajn rešetke i razvijena je i testirana ove jeseni. Amazon je rekao da je antena promjera samo 12 inča, manja i lakša od tradicionalnog dizajna antene. Testovi pokazuju da antena može pružiti maksimalnu propusnost do 400Mbps. Tvrtka je također istaknula da se ova antena može koristiti za prijenos 4K videa s geosinkronih satelita. Geosinkroni satelit je svemirska letjelica koja se nalazi oko 22 000 milja (oko 32 000 kilometara) iznad Zemlje. Međutim, satelit Amazon Kuiper bit će bliže Zemlji. Amazon je u srpnju ove godine dobio odobrenje Federalne komisije za komunikacije (FCC) Sjedinjenih Američkih Država za lansiranje satelitske skupine sastavljene od 3236 satelita za projekt Kuiper. Visina leta letjelice kreće se od 590 km do 630 km. S toliko mnogo satelita koji rade blizu Zemlje, projekt Kuiper će pojedinačnim korisnicima na Zemlji slati pokrivenost širokopojasnim internetom niske latencije. Njegov cilj je osigurati pokrivenost udaljenim područjima i regijama koje ne mogu pristupiti tradicionalnom brzom internetu.

Amazon je jedna od mnogih tvrtki usredotočenih na lansiranje ogromne svemirske internetske konstelacije. Vrijedno je napomenuti da SpaceX-ov program Starlink također cilja na isti cilj. Program se sastoji od gotovo 12 000 satelita i također će omogućiti širokopojasni internet od niske do srednje orbite. Trenutačno je SpaceX lansirao gotovo 1000 Starlink satelita i čak je započeo početno testiranje. Amazon još nije lansirao nijedan satelit i nije otkrio s kojom će se vrstom rakete ti sateliti lansirati. Amazon je rekao da smanjenjem veličine korisničkih terminala mogu smanjiti troškove proizvodnje hardvera i smanjiti cijenu po kojoj korisnici odlučuju pridružite se programu. Tvrtka tvrdi da mogu postići minijaturizaciju spajanjem mikro struktura elemenata antene zajedno. Prema fotografijama SpaceX korisničkog terminala koje su objavili beta testeri na redditu, Amazonova antena promjera 12 inča puno je manja od Starlink antene. Kako bi testirali SpaceXov Starlink hardver, beta testeri prvo moraju platiti 499 dolara za sve uređaje, a zatim plaćati dodatnih 99 dolara mjesečno. Amazon nije otkrio cijenu projekta Kuiper, no kompanija je obećala uložiti 10 milijardi dolara u projekt.
