The Federal Communications Commission today approved SpaceX’s proposed revisions in its plan to put thousands of satellites in low Earth orbit to provide global broadband connectivity, clearing the way to start launching satellites next month.

SpaceX already had authorization for 4,425 Starlink satellites that would use Ku- and Ka-band radio spectrum to beam internet data, but last November, the company asked the FCC to sign off on a plan that would put more than a third of the satellites in 550-kilometer-high (340-mile-high) orbits rather than the previously approved 1,150-kilometer (715-mile) orbits.

Eventually, SpaceX plans to add another wave of more than 7,500 satellites in even lower orbits to enhance the constellation’s coverage.
