Tesla and SpaceX founder Elon Musk is a man of great ambition, and among his plans is building a space satellite in space to spread the Internet over the Internet. Now this great project has come a step closer to achievement.
Like other Ars Technica reports, SpaceX recently received FCC approval, representing US communications authorities, to send 7518 broadband satellites to space.
Second round of approval
Musk and SpaceX have already received approval to launch 4425 satellites that took place this spring, and with this new approval, the rest of the project has gained green light.
In the press release on fresh approval, the FCC writes that SpaceX is now guaranteed flexibility to support a broad range of broadband and communications services for both private and commercial / professional users globally.
Satellites recently adopted by 7518 satellites are so-called very small satellites in the Earth's orbit (VLEO), which will open the ground at a height of 335 to 346 kilometers. They will use the 37.5 – 42 GHz frequency band for communications from the room to the back stations and 47.2 – 50.2 GHz for communication going in the other direction.
The constellation previously approved of 4425 satellites will be higher at an altitude of 1110 to 1325 kilometers.
One gigabit per second
Satellites will use a so-called phased array solution, which means that the antennas can "control" the beams to focus on where they need it most, with small field receivers that can track the satellites continuously.
SpaceX has previously said that the satellite communications system, hereafter referred to as Starlink, will be able to deliver an end user with a bandwidth of one gigabit per second after it enters into force and has been optimized.
The idea of the project is to offer users more options in the high-speed Internet and to spread the network in many parts of the world, including in areas where other infrastructure is underdeveloped.
As Reuters reported last month, SpaceX plans to run satellites in different phases by 2024 inclusive, but the goal is to use the system by 2020. We need to see how we will benefit from this project.
Facebook also tried to stack a similar project on its feet, then with drones instead of satellites, but this action was put on this summer.
