Video narration
How can ordinary internet come from satellites flying overhead, instead of one satellite staying above your home? Like your phone switching between cell towers while traveling. Your home’s user terminal—the Starlink dish—sends a request to a satellite in low Earth orbit, much closer than traditional high-orbit satellites. The satellite sends it toward ground infrastructure connected to the internet. On some routes, inter-satellite laser links pass it between satellites. The reply returns through the network, down to your terminal, and to your device. The key: it does not stay with one satellite. Your dish electronically tracks fast-moving satellites and switches as one moves away. So Starlink keeps a moving relay going, rather than waiting for one spacecraft to hover overhead. Service still depends on visibility, weather, traffic, and links to the wider internet. It’s a relay: your dish switches satellites, sending data to and from the internet.
