SpaceX’s laser system for Starlink is delivering over 42 petabytes of data for customers per day, an engineer revealed today. That translates into 42 million gigabytes. Each of the 9,000 lasers in the network is capable of transmitting at 100Gbps, and satellites can form ad-hoc mesh networks to complete long-haul transmissions when there are no ground towers nearby (like when they’re going across oceans).
That’s when there’s a ground station in view of the Starlink satellite. The laser links add latency, but it’s still a hell of a lot faster than GEO satellites.
