The first ever satellite to be successfully sent to space was Sputnik 1 by the Soviet Union in 1957.
When we look up at the sky, all we can see are stars, the sun, and the moon. What we can not see with our naked eyes are the invisible machines that circle our planet. These are called Satteliter, which make tracking GPS, telecasting live matches, and connecting overseas possible.
We have dug down to explain more about satelliter, their origin, how far satellites have come from Sputnik 1 in 1957 to today, and their contribution to modern living. Read this blog to gain knowledge about the topic!
Sattelitter is commonly referred to as an object that circles another object. Like the moon orbits around the Earth, making it Earth’s natural satellite. Similarly, man-made satellites are installed in space to orbit around and serve various purposes like research, surveillance, navigation, and communication.
These Sattelitters are not just simple machines, they are expert:
Thus, you can say that sattelitters are a small part of a constellation, but the only difference is that they do not move on a fixed orbit, plus, they are more agile and built on advanced technology.
Now that you’re introduced to what sattelitters are, let’s go ahead and understand their evolution in the next section.
The story of satellites came to light after humanity’s quest for innovation and conquering space. The motto was to study space physics, innovate new ways for communication, and observe Earth for the climate crisis.
During the 1950s, every country started inventing satellites, and the first successfully launched satellite was Sputnik 1 by the Soviet Union, which was a simple metallic machine with 58 cm in diameter. Sputnik 1 was sent to space on October 4, 1957, when the new era of modern satellite began.
Following that, Explorer 1 was launched by the United States in 1958, which opened new doors for meteorology and space science for the world.
During the 1970s–1980s, these machines improved weather forecasting and navigation through GPS. TV, internet, and mobile networks were transformed with the help of sattelitters during the 1990s and 2000s.
Talking about the current time, the space tech companies like SpaceX, OneWeb, and Amazon are working on developing mega-satellites to enforce high-speed internet globally.
Every satellite is designed to serve various purposes and comes in various shapes and forms. Mentioned below are the primary types of satellites and their functions:
Satellites are developed and properly installed in a particular region in space. So they don’t just float randomly but follow a path or orbit to serve their purpose of development.
These are the primary orbits where the satellites are installed:
LEO is 160 to 2,000 kilometres above the Earth. Since they are close to the planet, they move fast, circling the Earth in 90–120 minutes and can provide a high-resolution view and strong connectivity.
The main objective of the satellites here is to observe Earth closely for weather forecasting and provide images, navigate constellations, and improve GPS connections.
The altitude for MEO is 2,000 to 35,000 km above the Earth’s surface. The satellites placed here do not move as fast as LEO but cover a larger region. The time taken to circle the planet is around 2–24 hours, and because of more coverage, they offer broader connectivity and range.
GPS, GLONASS, and Galileo are the navigation systems that follow the MEO range. Moreover, MEO satellites can move to Geostationary orbits for adjustments in coverage areas.
Geostationary orbit is considered at 35,786 kilometres above Earth. The satellites here circle at the same speed as the Earth and are mounted at a single spot for continuous coverage of a region.
The major applications are weather satellites, television broadcasting, and long-distance communication.
Polar orbit is 500 to 1,000 kilometers above the Earth’s surface. The satellites mounted here move through the North Pole and South Pole and scan the regions strip by strip. They capture images of every location of the planet, which is helpful in studying changes in forests, ice caps, and the monitory climate.
These orbits combined form the layered satellite’s orbital ecosystem. Thus, no matter whether you are in a city, rural area, or arctic region, you are always monitored and connected.
Each part of the satellite is carefully designed by the engineers, assembled in labs, and tested rigorously to serve the purpose of development. Since the launch of the first one to date, satellites have changed the world for the better.
Here are the powerful benefits of sattelitter technology:
Sattelitter technology is the driving force behind building the new age space machines that are smart to operate and orbit seamlessly.
There’s no doubt that satellites have improved modern living drastically; however, it is important to point out the challenges this technology comes with.
All the powerful nations in the world are working tirelessly to improve and innovate sattelitter technology. So it is safe to say that the future will be exciting as well as challenging.
These are some advancements that we will surely see in the near future:
Satellites or sattelitters are guardians monitoring every move on the earth in this digital age. They are the reason for our climate forecast warnings, overseas communications, and strong defense force. However, these machines had a humble beginning in the 1950s and are now the greatest technology in the world.
We have covered everything from the evolution of sattelitter technology, types and functions, to the future ahead in this blog. Hopefully, the information has given you a clearer perspective on how satellites work.
The first ever satellite to be successfully sent to space was Sputnik 1 by the Soviet Union in 1957.
More than 8000 satellites 2025 are actively orbiting Earth, with thousands of inactive junk.
The modern satellites are AI-powered, eco-friendly designs, and smart to self-destruct after the mission to reduce space waste.
