Hello friends, today we are going to talk about satellite , in which we will tell, what is a satellite or satellite (what is a satellite) , how does a satellite work, types of satellites, uses of satellites and satellites .. What is the definition? To know the information about all these topics in detail, let's start the satellite ?
Satellites provide services in a variety
of areas, such as broadcasting TV programs around the world, remote phone calls, weather information, news reports, Ola/Uber taxi booking , Google Maps , vehicle tracking, and monitoring the location or hostile country. Through a navigation through GPS global positioning system ( the GPS ) and much, go all of them with the help of the satellite to get different types of information. In this post, let's find out what a satellite is, and understand the
characteristics and types of a satellit
.
The meaning of the satellite
Meaning of the satellite : The satellite is called a "satellite" . The word "satellite" means an object orbiting the Earth or a planetary object in space. There are two types of satellites, the first is natural satellites and the second is artificial satellites .
Natural satellites are those that are not made by man, for example - the Moon is a natural satellite of the Earth because it revolves around the Earth's orbit. The satellite, a man-made satellite, launched from the Space Research Institute of different countries, which orbits the Earth 24×7 in Earth orbit. Such as - Sputnik 1 , Rohini Satellites .
Definition of satellite
Satellites are things created naturally or by humans. An object that revolves around another large object (planet) in space is called a satellite. It can be circular or elliptical in the path of the orbit of any planet. The larger body carries all the smaller bodies that revolve around it and gives them life, light, heat and energy. For example - Earth is a natural satellite of the sun because it revolves around the sun.
What is a satellite (what is a satellite)
We can easily understand a satellite , it is a small body that orbits 24 x 7 in space around a larger body than it. A moon that revolves around the earth can also be called a satellite, but it is the only natural satellite of the earth, which does not operate under human control or any technology, but on the basis of the rotation of the moon, humans made In human development, it is one of the means of human life development.
Man-made satellites can range from the size of a small television to the size of a large house, depending on the size. Solar panels are installed on both sides of the satellite, where the satellite derives energy from sunlight and is converted into electricity, while in the middle of the satellite there is a transceiver through which the work of receiving or transmitting the signal is made. Besides, some control drives are also installed, with which a human can remotely control the satellite from the ground and change its position, or if the angle of the satellite has to be changed, then all things are done by this control drive.
Satellites are designed for different missions, you can easily see this object in the satellite, like the satellite is designed to capture the image of the hurricane on Earth, the satellite also has large cameras that can see the entire ocean. It is designed to scan, then you will see a scanner in it, this one is high-quality, it all depends on the work of the satellite.
types of satellites
There are many satellites in the solar system including the Earth and the Moon. So, based on the presence of planets in space, satellites are divided into two main categories:
- natural satellite
- Satellite
natural satellite (natural satellite)
Those satellites that are not made by man are called natural satellites, for example - planets like Earth, Jupiter, Uranus, Saturn, Neptune and Mars revolve around the sun in a fixed orbit, so all these planets are called the sun. Natural satellite. The Moon is also a natural satellite of the Earth as it revolves around the Earth. Natural satellites are called satellites.
The sun is one of the billions of stars in the galaxy that make up the entire solar system. It takes the central position in the solar system and provides all the resources to the planets. There are more than 218 natural satellites in the solar system. Most of these planets have moons orbiting the major, minor, and other planetary bodies of the solar system, but only a few of these planets are very large and perfectly spherical in shape. For example, Jupiter and Saturn.
Satellite
Satellites that are man-made are called satellites. It revolves around the Earth and other planets in the solar system . Man-made satellites are launched by rockets, which shoot vertically from the Earth's surface, after which they are placed in orbit of the Earth or other planets in space. A satellite is called a satellite.
Satellites are also used to broadcast television, gather information, help people communicate, study Earth or other planets, and even observe the distant universe. The world's first artificial satellite created by humans is Sputnik 1 , which was launched by the Soviet Union in 1957. The names of some of the satellites launched by humans into space are Sputnik 1, Rohini, Vanguard 2E, Luna 2, Ranger 6, Aryabhata, Bhaskara-1 and Chandrayaan -1 etc.
How does a satellite work?
There will be a question in your mind about how the satellite works , in such a case you must have known what is the meaning of satellite and satellite, now you know, how do satellites stay in the open universe in space or how do they work.?
The satellite does not actually fall to the ground or why not get lost in space, the reason for this is very simple, such as if anything should be kept in space or should stay, it has to move on its own the speed of an object greater than it should rotate as that Its speed does not allow the force of gravity to control it. Due to the force of gravity, the satellite remains in space, operating on the basis of this law. In this energy solar panels are installed , due to which solar energy is converted into electrical energy , and in this way the satellites work.
Basically, we use satellites to communicate nowadays, they develop communication very easily, because radio and terrestrial web are not fully used in communications on Earth, so most of the satellites are used for communication.
uses of satellites
Military satellites: Military satellites are used to spy, survey and track enemy country targets. These satellites scan the site for enemy objects and provide the host country with images and information there.
Weather forecasting: Satellites help in forecasting the weather on Earth, monitoring weather conditions, predicting any weather conditions such as storms, hurricanes and heavy rain, and dealing with disasters effectively.
Navigation: One can easily reach from one place to another by navigating with the help of satellite and can know the distance from one place to another sitting in the same place and what are the things around it. For navigation, GPS locators are used towhich satellites are connected.
Telephone: The satellite helps to have a wireless telephone connection with anyone in any corner of the earth and works in any weather.
DTH TV Broadcasting or TV: We can watch live TV programs from satellite without using any TV program like cable, cricket footage is broadcast by satellite signal.
Climate and Environment Monitoring: A great resource for information on climate change research by satellite. Satellites monitor ocean temperatures. Satellites can measure the changing shape of the glaciers, which are difficult to observe from the ground.
Briefly:
As you know what is satellite , satellite communication has helped industries a lot in bringing about change in business. New mobile applications have been built using satellite technology, which we use to obtain navigation and other information and it connects stakeholders to the business.
