Internet for all via satellite: this is The goal of OneWeb Initiative, in which Airbus is involved. With a Soyuz rocket, the first of six satellites to start now. In the end, it should be 600.
With light speed browsing: This suggests the advertising of Internet providers already now, when it comes to a glass fiber connection. In this case, light propagates in the glass fiber is not as fast as you might think. There, 70 percent of the speed of light in a vacuum is just reached. Exactly at this point, Greg Wyler, founder of OneWeb Initiative, sees an opportunity in so-called satellite-mega-constellations.
The OneWeb Initiative wants to shoot 600 satellite into space. You should revolve in about 1000 km height.
The OneWeb Initiative aims to raise 600 satellites in the space, the Space X to be Starlink network even 4500. The satellite erdnah circles. Erdnah about 1000 km means high. This is close enough so that signal reception at the earth’s surface with special devices is possible. In addition, signals need to cross the near-earth space shorter maturities than in the submarine cables that connect the continents.
stock market trading needs a blazing fast Internet
In the worldwide stock exchange trading, it comes down to milliseconds.
For normal Internet users the speed difference is irrelevant. The worldwide stock market trading, for example, is the exchange of data on every fraction of a second time advantage.
For faster Transfer to The Internet by satellite can also be in remote regions of the world receive, if it is possible to cover the entire earth with such a network. The large numbers are necessary. The current number of Satellites in space would double at a stroke.
satellite is a mass-start saving money
Because each rocket launch costs a lot of money, you need to be the satellites are relatively small and slightly built. This is technically possible in the meantime. A Soyuz rocket should be able to blow up to a 40-OneWeb-satellite transport. It is only through this mass starts, the project is even financially feasible.
Multiple OneWeb-satellite-wait for the loading.
The disadvantage of mass production: A design error would be equal to hundreds of satellite copies. Turns out, for example, when operating in world space, in the interior of the satellite battery gas bubbles form, you can only watch, as the gas pressure brings the battery cells to Burst and one satellite after the other destroyed.
So it is just the US environmental protection Agency with an older satellite batch. So the latest technology could be in the worst case, to space junk. The want to avoid the engineers, by directing the Websatelliten at the end of their time-of-use directly into the earth’s atmosphere as an artificial shooting stars burn up.
