This isn't going to let them jump past national regulatory agencies. It will help them avoid local regulations and right-of-way issues that helped kill Google fiber.
Where did you get the $10 billion number from?
- 167k per sat construction cost
- 20 mill per launch (at-cost WAG)
- 333k launch costs per sat
- 500k per sat total cost
these numbers give a final 12000 sat constellation cost of 6 billion. The initial 1600 sat constellation comes to 800million
But if my assumptions are off, it could be way less or more. If they make the satellites even cheaper, or at cost launches are less, or they end up being able to launch on Starship, it's significantly less. If sats cost more, or launches are more, then the cost goes through the roof.
