Hello everyone, since I am a lover of innovative technology by leafing through one of my favorite magazines Focus, I found an article about internet and satellites that in the space of a few years, the Earth will be filled with at least 13,000 new telecommunications satellites. such as to cover also now difficult to reach areas!
Consider that over 12 years, the number of people in the world with access to the Internet has increased from about one billion to about 3.5 billion: 🤔 15% to half the world’s population … incredible! It is estimated that over the next ten years the Internet will reach 5 billion people, or 70% of the (current) population of the planet. In order to support this continuous growth, however, the main communication companies will have to increasingly take into account satellite networks. It is in fact in the coming months that we will start with the launch in orbit of new “constellations” of telecommunications satellites, capable of bringing the Internet to a capillary level in every corner of the world.
I will try to summarize what I have read also because he read a lot of pages and I do not want to go long 😂.
First of all, in order to obtain an Internet network at a global level, we need to take into account 3 basic things
• a considerable amount of satellites so you can create
a capillary connection.
• a large number of ground stations called NOCs
(Network Operations Center: the systems that make up
link between web content and satellite infrastructure)
• each user must have a parable (to receive the
signal) and a modem (to transmit to the NOCs).
And the big companies are also investing in “sleeping” satellites these to keep the connection constant and to never leave any areas absent in the event of a satellite failure these “sleepers” would automatically activate, thus ensuring a smooth connection!
Very interesting is the world of satellites of this in the constellations Satellitar in 2019 will be ready already 8 new constellations these will have 2 different orbits that are distinguished by low orbit and medium orbit:
• low orbit named with LEO (low-earth orbit) with a surface distance between 160 and 2000 km!
• medium orbit denominated with MEO (medium-earth orbit) which distances from 2000 up to the geostationary limit which is approximately 35,000! There is to be specified what new to me that the more the constellation is close to the surface, the less signal power is needed to communicate, but the less time is available for an operator to remain connected to a single satellite (as they move very fast): to guarantee quality and the continuity of communication, a network located in low orbit must therefore be composed of many satellites, even a few thousand.More higher is the minor orbital odds is the total number of satellites of that constellation and the longer remains “visible” a single satellite to the individual operator, but, of course, the energy required for communication is greater.
Well by 2021 it is estimated an amount of about 15000 satellites scattered in these two orbits so that they can be spaced from each other even 20 km and in this case the probability of clash between them would rise significantly even if they claim that the satellites have a displacement margin falling within the limits ..
Well, it will not wait for us to wait until 2021 to observe our planet sprinkled by these spacecraft which, moreover, will allow thanks to the advanced technology of never feeling alone even in the middle of the ocean and the desert!
I hope the post has been to your liking☺
