A satellite can be defined as an object that keeps revolving (or obits) around specific elements in space. Although some satellites are natural, such as the moon which orbits around the sun, others are man-made. In the modern era, satellites are typically referred to like all the artificial objects that are flown in space. Just like their natural counterparts, these satellites also orbit around the planets, but the only major difference is that man-made satellites are intentionally placed into orbit.
Artificial Satellite’s history stretches back to 1957, when it was launched into space by the Soviet Union – it was named Sputnik 1. Since then, around 9,000 satellites have been launched from over forty countries around the world. Sounds big, right?
Although this article focuses on the overall functionality and mechanism of satellite communication, if you wish to know about any of its other features or origin, then do reach out to some reliable tech-related websites on the internet.

However, before you begin your research, just make sure that you connect to a high-speed internet connection like CenturyLink so that your web pages do not take extra time to load. CenturyLink offers high-coverage internet connectivity round the clock for all types of online activities like gaming, downloading, streaming, etc. Apart from this, CenturyLink internet plans are super-affordable for all types of users – they are starting from only $50 per month.
Artificial satellites are used for several purposes, such as forming star maps, planetary surfaces maps, and also to capture pictures of planets they are sent into for orbiting. Some of its most common types include communications satellites, navigation satellites, civilian and military earth observation satellites, space telescopes, weather satellites, etc. All of these satellites are semi-independent and work through specific computer-controlled systems to carry out a wide range of tasks, like thermal control, power generation, attitude, telemetry, etc.
Now that we have a clear idea of ‘what’ is a satellite, it’s time for us to find out ‘how’ it works.
How Does Satellite Communication Work?
A satellite works through a high-end, self-contained communications network that receives signals from earth and retransmits them back with the help of a transponder. During the communication process, satellites have to withstand the strong effect of being accelerated and processed during launch – its orbital velocity is of 17,500 miles/hour which is obviously huge. The space contains a pretty hostile environment for the satellite where it’s typically subjected to extreme radiation and hot temperatures to carry out the whole communication process. Surprisingly, sometimes its overall operational life can last up to twenty years. Not only that, NASA scientists have to ensure that the artificial satellites are light, as the cost of its launch is extremely expensive since it’s based on their total weight.
So, to meet these standards, an ideal satellite must be small and made up of durable, and lightweight materials. Also, NASA scientists have to ensure that these man-made satellites operate at extremely high-reliability rates of more than 99.9% in the vacuum of space, and have no prospect of any major damage or repair.
Communications satellites amply radio telecommunications network signals via specific transponders. In simpler words, these satellites create a communication channel between a source receiver and transmitter at several locations on earth. Currently, there are over 2,000 artificial satellites being used for telephone, television, internet, radio, and military applications – these serve both government and private organizations.
Besides this, there are numerous other man-made satellites in the geostationary orbit 35,785 km above the equator. Their orbital period is just the same as the rotation period of the Earth – it allows the satellite dish antennas on earth to be aimed perfectly at that spot. Thus, they do not need to track or move along with it.
For example, the satellite internet typically works via geostationary satellites. It provides better network coverage in rural areas where DSL is not accessible. The best part is that the advanced satellites are using the Ku band to provide downstream data speeds to their users, up to 506 Mbit/s. However, we need to remember that satellite internet is still not the first choice for people living in urban areas, as they have fiber-optic and DSL internets, which offer higher speeds than satellite internet. So, satellite internet is particularly useful for people living in remote areas that do not have access to high-quality broadband connections.
If you live in a city, we recommend you opt for a faster internet type like DSL or fiber-optic so that you can enjoy nonstop browsing, streaming, and gaming round-the-clock. Just in case, you are looking for a reliable, and high-speed internet connection in your area, do check out Spectrum internet.
The best part is that Spectrum also offers some amazing TV and internet bundles as well – now you can easily bundle up your internet services with TV plans to enjoy 24/7 streaming and downloading on the go. So, if you are looking for some high-coverage TV plans, then don’t forget to check out the latest Spectrum Select TV package. It offers more than 125 channels to all its users at only $49.99 per month, and that too in HD quality.
For more details, please reach out to Spectrum’s official website, or simply call their official customer services helpline.
Due to the immense development and advancement in the field of satellites communication, we can predict that in the next era satellites are surely going to be a game-changer for the internet world. There are several well-funded organizations across the globe that have already begun their satellite launch campaigns and others are moving in the same direction too. And to be honest, that’s some good news – once the satellite internet manages to supersede the speed of DSL and fiber networks, we’ll see a massive change in the tech industry in various ways.
We hope you enjoyed learning about satellite communications with us. Although we have tried to cover all the basic information about it in the previous paragraphs, if you wish to know more about its functionality, origin, or any other aspect, please feel free to reach out to some reliable NASA or tech-related sites on the internet. They will provide you with a broader view of how satellite communications work, along with its pros, cons, types, and several other specifications.
However, before you begin your research, just make sure that you connect to a high-speed internet connection like Xfinity so that you can enjoy a smooth, and lag-free browsing experience.
