With Starlink Internet, data is continuously transmitted between a ground dish and a Starlink satellite located 550 km above the ground. Plus, the Starlink satellite zooms through the sky at a speed of 17,000 miles per hour! How can the dish and satellite maintain a continuous connection? And how is data sent back and forth? In this video we take a closer look at the inner workings of the ground dish and the Starlink satellites, and see how a data beam is formed, how this beam is swept through the air, and finally what exactly is inside it. beam that makes incredibly fast internet possible! This is an incredible feat of technology and engineering, so stick around!

Erratum:
At 2m50s the trajectories are inaccurate. The TV satellite must be in geostationary orbit and moving in the same direction as Earth. In addition, all Starlink satellites would have to orbit from west to east. Thanks to Paul S.
