Tesla and SpaceX founder Elon Musk is a man with great ambitions and among his plans is to build a satellite-based network in space to spread the Internet Internet. Now this great project has come a step closer to the realization.
Like other Ars Technica reports, SpaceX recently received approval from the FCC, representing the US communications authorities, to send 7518 broadband satellites in space.
Other approval company
Musk and SpaceX have already received approval to launch 4425 satellites that happened in the spring, and with this new approval, the rest of the project has now received green light.
In the press release on free approval, the FCC writes that SpaceX is now secured flexibility to support a wide range of broadband and communications services for both private and commercial / professional users globally.
The recently adopted 7518 satellites are so-called very low terrain satellites (VLEO), which will run around the globe at a height of between 335 and 346 kilometers. They will use the 37.5 – 42 GHz frequency band for communication from the room to the back stations and 47.2 – 50.2 GHz for the communication as well as on the other.
The previously approved constellation of 4425 satellites will be higher up at an altitude of between 1110 and 1325 kilometers.
One gigabit per second
The satellites will use a so-called facade array solution, which means that the antennas can "control" the beams to concentrate those where the need is greatest, with small receivers on the ground that can track the satellites continuously.
SpaceX has previously said that the satellite system, otherwise called Starlink, will be able to deliver a gigabit per second bandwidth per end user after it has come into place and optimized.
The idea of the project is to give users more options in high-speed internet and to spread the network to more parts of the world, including areas where other infrastructure is poorly developed.
As Reuters reported last month, SpaceX plans to broadcast satellites in different phases up to 2024, but the goal is for the system to be used by 2020. Just how we will benefit from the project remains to be seen.
Facebook has also tried to stack a similar project on the legs, then with drones instead of satellites, but this bet was hit down this summer.
