How does the satellite work? Many people want to know how a satellite works, whether it is used to transmit television broadcasts or take pictures from abroad, and we will learn everything about how a satellite works, but first we will learn what a satellite is. industry.
Satellites
Before we get into how this device or this device works, we will get to know it and its components, as many people want to know the details of this device and how this device works, and to know the most important information on this device as follows: –
- It is a piece of iron and wire of a certain type for a specific purpose and is installed and processed on the ground.
- Spaceships are used to assist satellites in space travel, which means they are part of the expedition into space, and satellites are sent into space for many reasons.
- The satellite works during its transition into space under the influence of two main forces, the centrifugal force, and works to pull the satellite circle around the earth without falling, and the satellite by centripetal force, which are the other forces, so that it does not float in the great space, and these two operations take place in parallel.
- The satellite rotates in a circular orbit around the earth, and its speed and movements are determined by the radio link from the ground.
- It works on two main factors, the first to receive broadcast signals that help transmit movements on television and transmit sounds on the radio, and the other to take pictures of the Earth from the outside.

The first satellite
- The idea began with the scientist Isaac Newton, who discovered gravity, and it is one of the most important discoveries, but humanity took a lot to design the first satellite to orbit the Earth.
- The first satellite that came into space was in 1945, and this was the first time that something entered space, because it revolves around the Earth in a circular path, at a certain speed, and has a monthly cycle that is completed every month and has an annual cycle that is completed every year, which is impossible. He bumps into something out of his way.
- It launched the first satellite from the Soviet Union, and the first satellite was called Sputnik 1, and the name of this satellite was a small piece of metal with a circular shape, and it weighed 85 kilograms, as it is completely different from the satellites that exist today around the Earth.

What is in the satellite
The dimensions of the satellites and the internal components of each available satellite vary according to the country that launches the satellite, but here are some parts that never change and we will learn about them in detail as follows:-
- The iron structure is hollow to carry all the internal components of the satellite, and it must be of a certain thickness, solid and strong so as not to burn in the atmosphere and to be strong against any other influence in the atmosphere.
- It must be a source of energy and energy sources differ in two ways, the first method is solar panels, that is, the distance from the earth makes it difficult to charge them, which results in a lack of knowledge of the type of charge, and scientists say that sunlight is considered the best method for renewable energy. If the method succeeds, then it becomes basic, and if it does not succeed or in the event of any malfunction, we move to the other method, that is, in the event of a defect in the batteries and solar panels placed on the satellite, it will work until the error is fixed.
- A computer inside the satellite. This device is connected to a device on the ground. This device controls the rotation and speed of the satellite, the degree of clarity, broadcast signals, and many other settings. If this device fails, the satellite becomes unusable.

How does the satellite work
We will learn a lot of information about how the satellite works, and from the first work steps, how to make this tool fly in the sky, and this is achieved by studying the working speed factor to obtain all the force factors, whether it is centrifugal force or gravitational force. It works at speed which is as follows: –
To overcome the Earth’s gravity in space, the satellite must move at speeds of up to 7.5 kilometers per second.
How do broadcast satellites work?
Many people want to know how to turn on the TV at home, and we will learn how the satellite works on the air and the TV is turned on at home, and this is done through the following steps: –
- After the producing company completes the video or advertisement, it hands over the equipment and the TV broadcasting channel or department to send the signal.
- The film or advertising tape is placed on this device, and the transmitting dish sends many waves to the satellite, which is received by the satellite in space.
- The airborne satellite device sends all the waves back to every dish or receiving station in the real estate, apartments, houses or villas, so the television plays the waves emitted from the satellite.

How do satellite imaging work?
Not only does a satellite device rely on broadcasting TV signals, but it also performs many other tasks which we will learn as follows:-
- Satellites can see many large areas floating above the Earth’s surface.
- It is equipped with high-resolution cameras in different geographical areas.
- It can provide topographic photography, traffic photography, climate photography, weather conditions and many other useful situations in daily life.
- He can also discover many natural resources on Earth.
- It explores many resources in the sea, including gases, oil and coal.
- And all these discoveries work on many advantages that we will learn.
Benefits of the satellite imaging business
There are many achievements that humanity has achieved with the operation of this device, and we will learn about the most important achievements made by satellites around the world as follows:
- Satellites provide a way to catch up on world news on TV and radio and keep up to date for free for anyone.
- Satellites provide many entertainment opportunities by watching TV series, movies, comedy programs, and others, which are among the reasons for entertainment for some.
- She provided many images of the space monster that helped make architectural breakthroughs based on space measurements.
- It works to provide all kinds of comfort and is considered one of the most important and oldest ways in societies.
In this article, we learned how a satellite works and got acquainted with the first satellites, what satellites are inside, how satellites work in broadcasting, how satellites work in imaging, and we talked about the benefits of making satellites in imaging.
