Starlink satelitski internet: put podataka od tla do orbite

Dokumentarni film prati jedan DNS upit kroz svaki korak satelitske mreže — od fazno-polje antene na tlu, kroz laserske međusatelitske veze na 550 km visine, do gateway stanice i natrag. Objašnjava kako DVB-S2 standard kodira signal da preživi svemir i zašto GEO satelit neizbježno donosi kašnjenje od 600 ms. Globalni kvar Starlinka u srpnju 2025., koji je prekinuo komunikaciju ukrajinskim postrojbama 150 minuta, okvir je za središnje pitanje: tko kontrolira taj put?
