With Starlink internet, data is continuously being sent between a ground dish and a Starlink satellite orbiting 550km above. Furthermore, the Starlink satellite zooms across the sky at 27,000km/hr! How can the dish and satellite maintain a continuous connection? And then how is data sent back and forth? Well, in this video we’re going to dive into the inner workings for the ground dish and Starlink satellites, and see how a beam of data is formed, how this beam is swept across the sky, and then finally what exactly is in that beam that allows for incredibly fast internet! This is an incredible feat of technology and engineering, so stick around!

Erratum:
At 2m50s, the orbits are inaccurate. The TV satellite should be in geostationary orbit moving in the same direction as the Earth. Furthermore, all the Starlink satellites should be orbiting West to East. Credit to Paul S.
