Amazon will be launching 3,236 satellites into low Earth orbit. They will be at an orbital altitude of 367 miles to 391-miles. This will be an Amazon project and not a Jeff Bezos Blue Origin project.
SpaceX is trying to raise another $500 million for its Starlink satellites. They should be placing near production ready prototypes starting next month. There will be about 75 satellites in prototype configuration of the planned 4425 satellites. SpaceX will likely have to raise several billion more. They could start an operating satellite business with an initial 800 satellite constellation and could provide coverage for the northern hemisphere with 1600 satellites. SpaceX had filed for a license for another 7518 satellites using the V band.
