The founder of Tesla and SpaceX, Elon Musk, is a man with great ambitions, and among his plans is the construction of a satellite-based network in space to spread the Internet on the Internet. Now this great project has come a step closer to achievement.
As among other reports from Ars Technica, SpaceX recently received approval from the FCC, representing the US communications authorities, to send 7518 broadband satellites into space.
Second round of approval
Musk and SpaceX have already received approval for the launch of 4425 satellites, which happened this spring, and with this new approval, the rest of the project has gained a green light.
In the press release that deals with the new approval, the FCC says that SpaceX now has the guaranteed flexibility to support a broad range of broadband and communications services for private and commercial / professional users worldwide.
The recently adopted 7518 satellites are the so-called very low-Earth (VLEO) satellites that will pave the Earth at a height between 335 and 346 kilometers. They will use the frequency range of 37.5 – 42 GHz for room communication for background stations and 47.2 – 50.2 GHz for communication going to the other side.
The previously approved constellation of 4425 satellites will be higher at an altitude between 1110 and 1325 kilometers.
One gigabyte per second
The satellites will use the so-called phased array solution, which means that antennas can "control" the beams to focus those where the need is greatest, with small receivers in the ground that can continuously track the satellites.
SpaceX said earlier that the satellite system, also called Starlink, will be able to deliver a bandwidth of one gigabit per second per end-user once it has been deployed and optimized.
The idea of the project is to give users more options within the high-speed Internet and spread the network to more parts of the world, including areas where other infrastructure is underdeveloped.
As Reuters reported last month, SpaceX plans to broadcast satellites in different phases by 2024, inclusive, but the goal is for the system to be used by 2020. The way we will benefit from the project continues to be seen.
Facebook also tried to stack a similar project in the legs, then with drones instead of satellites, but this venture was shut down this summer.
