> The lasers, which can sustain a 100Gbps connection per link

> Brashears also said Starlink’s laser system was able to connect two satellites over 5,400 kilometers (3,355 miles) apart. The link was so long “it cut down through the atmosphere, all the way down to 30 kilometers above the surface of the Earth,” he said, before the connection broke.

How do these tiny satellites achieve this kind of accuracy and link quality when they're shooting around Earth with 17.000 miles an hour?

(Meanwhile, me on Earth, has link quality issues due to a speck of dust on a fiber connector)

Phased array antennas probably have a lot to do with this. You can aim the signal more accurately and faster than any mechanical system ever could.

Surely the lasers aren't phased arrays.
