SpaceX received approval for a change in the scheme of installation of the satellites Starlink

The Federal communications Commission (FCC) approved the request of the company SpaceX to launch large groups of its own Telecom satellites in a lower than indicated in the original plans, orbit. The absence of this permission, stood by the wall for the company before starting the first part of the total weight of the planned constellation of satellites, scheduled to be held next month.

In November last year, SpaceX filed a request for a partial revision of plans for groups of its future satellites, which it plans to use to cover the whole Earth with broadband Internet. Project, we recall, called Starlink. According to an earlier agreement with the FCC, the company received permission to launch satellites 4425 Starlink, and planned to place them at different heights from 1110 to 1325 kilometers above the planet’s surface. However, tests of two already derived earlier test satellites TinTin TinTin A and B, which will also be part of the future of the satellite constellation, the company has forced SpaceX to rethink its decision. Now the company is focused on the output 1584 satellites in different altitude. Is 1150 kilometers SpaceX plans to place them at an altitude of 550 kilometers.

As pointed out in SpaceX, the ability to place the Starlink satellites in a lower orbit will reduce the delay time of signal transmission of up to 15 milliseconds. In addition, the lower orbit will allow it to use less than 16 satellites, which in turn will reduce the risk of potential volumes of debris. The reason is that at the height of 550 km above the Earth’s surface the satellites will be more susceptible to the atmosphere of the planet, and their output to the desired height in this case will be carried out much faster. Thus, in the case of satellites down, they can go much faster with orbit and burn up in dense layers of the atmosphere, not to join the ranks of the already huge amounts of near-earth space debris.

However, with this decision I agree SpaceX was not all. The British company OneWeb, which is also about to bring into orbit a large group of its online satellites and satellite Communications operator Kepler petitioned for the failure of the company Ilona Mask on making edits and FCC permits to change the working height of the satellites SpaceX. Both companies drew the Commission’s attention to the fact that as the Starlink satellites use the same satellites with their frequencies, they can interfere with their equipment if they are to be in a lower orbit. After the test, the FCC issues this is not found.

“After reviewing the technical edits SpaceX, we came to the conclusion that the Starlink satellites should not pose significant problems for other satellite operators and meet the public interest,” reads the explanation from the FCC.

There was also concerns about the increased risk of collision of satellites, SpaceX with the satellites of other operators as they operate on similar orbits. But here, the Federal communications Commission of the USA found no problems, said the dangers satellites Starlink not present, as they are equipped with engines, which, in the event of a collision risk, they will be able to change its location.

Recall that SpaceX plans to bring into orbit a total of almost 12,000 satellites, of which she is going to cover all corners of the world with broadband Internet. In these endeavors, the company Elon musk is not alone. For example, the above company OneWeb has already launched its 6 satellites of the 650 planned. Recently, Amazon also announced plans to build and withdraw 3236 satellites in the framework of the project Kuiper, to be used for the same purpose.

Received permission from the FCC will allow SpaceX to launch over the next six years at least half of its planned satellites.
