SpaceX has received approval to change the satellite circuit Starlink

Federal Communications Commission (FCC) approved the SpaceX company's request to start a large group of its own telecommunication satellites in a lower than stated in the original plans, low-Earth orbit. The absence of the authorization for the company stood the wall before you start the first part of the total mass of the satellite constellation scheduled to be held next month.

SpaceX has received approval to change the satellite circuit Starlink

In November last year, SpaceX has filed a request for a partial revision of plans for its future satellite groups, which it intends to use to cover the entire earth's broadband technology. The project, as we called Starlink. According to an earlier agreement with the FCC, the company received permission to launch satellites Starlink 4425, and planned to place them at different heights from 1110 to 1,325 kilometers above the planet's surface. However, tests of two already withdrawn before the test satellites A and TinTin TinTin B, which will also be part of the future of the satellite grouping, SpaceX has forced to reconsider its decision. Now the company aims to conclude in 1584 the satellite at a different height. Instead of 1150 kilometers SpaceX plans to place them at a height of 550 kilometers.

As pointed out in SpaceX, Starlink possible to place satellites in the lower orbit will reduce the signal transmission delay time with devices up to 15 milliseconds. In addition, a lower orbit allows it to use 16 satellites smaller, which in turn will reduce the risk of potentially debris. This is explained by the fact that at an altitude of 550 kilometers above the Earth satellites will be more affected by the planet's atmosphere, and the their output to the desired height in this case will be carried out much faster. Thus, in the case of satellite failure, they will be able to go much faster orbit and burn up in the atmosphere, rather than join the ranks of the already huge amounts of near-Earth space debris. However, with such a decision agreed SpaceX were not all. Oneweb British company, which is also going to bring into orbit a large group of their online satellites and satellite operator Kepler Communications filed a petition for denial of Elon Musk on making corrections and FCC approvals replace the working height SpaceX satellites. Both companies are focused on the commission that since Starlink satellites use similar frequencies with their companions, they may interfere with their equipment if they are at a lower orbit. Audited, FCC problems not found.

"After reviewing the technical revisions SpaceX, we came to the conclusion that Starlink satellites should not pose significant problems for other satellite operators and the public interest", - says the FCC explanation.

have also expressed concerns about the increased risk of collision SpaceX satellites with the satellites of other operators, since they are working on similar orbits. However, here the Federal Communications Commission has not found any problems, pointing out that the danger of Starlink satellites are not as equipped with engines with which, in the event of a collision hazard, they will be able to change their location.

Recall that SpaceX plans to put into orbit a total of nearly 12 000 satellites with which it is going to cover all corners of our planet broadband internet. In these endeavors, the company Elon Musk is not alone. For example, the above OneWeb company has already launched its 6 satellites of the 650 planned. Recently, Amazon has also announced plans to create 3236 and the conclusion of satellites in the framework of Project Kuiper project, which will be used for the same purposes. Received permission from the FCC will allow SpaceX to launch within the next six years at least half of its planned satellites.
