About Artificial Satelite

Artificial satellites are satellites invented in outer space process.

How it works

The artificial satellite is rolled around the earth in such a way that the centrifugal or external power of its motion gives it the outside motion - but the gravitational force of the earth does not allow it to flow out of the Earth's atmosphere. Both strength balance the artificial satellite and the satellite is circling around the Earth. Since the air does not exist in the air, it is invisible. Artificial satellites do not navigate through the circle, its speed is oval.

Satellite satellites that transmit TVs and radio signals and weather observatories are usually located 36 thousand kilometers away from Earth.

The data is transmitted from the Earth using the radio waves, the artificial satellite receives and magnifies and sends them to the Earth. Artificial satellite uses two different frequency waves to capture and send the signal. Signals coming from earth to artificial satellites are very weak or low energy, so the signal is first concentrated using the dis antenna, and then receives the receiving receiver and used it for the necessary purposes.

Artificial satellite fuel

There is enough energy to be taken during the launch of artificial satellites. Because there is no chance of refueling in space. However, some satellites use solar energy as fuel. The solar cells are fitted on them, from which they accept the energy they need from the sun.

First artificial satellite

The credit of launching the first satellite in space was the former Soviet Union. The Sputnik-1, an airborne satellite that was launched on October 4, 1957, was designed by Sergey Karaliov, [3] a Ukrainian name In the same year, the Soviet Union launched the second artificial satellite Sputnik-2 in space. A dog named Sputnik-2, Lyca [4] was taken away. However, in the few hours of the launch, LICA died due to the error of heat control. The United States plans to send satellite to space in space in 1945. Their plans were successful on January 31, 1958. Their first artificial satellite Xplorer-1 was launched in space. India's first space satellite ASTROSAT.

Meteorological Satellite Satellite

The first weather satellite Vanguard-2 was thrown on 17 February 1959. It could collect weather information and send it to the world. Tyros-1, it was released from Earth on April 1, 1960, which was able to send pictures of earth's meteorological details in detail. In that year on November 23, Tyros-2 measures radiated infrared or infrared rays from the earth and collects weather photos. Hurricane Iather, a hurricane thrown in the Atlantic Ocean, was first discovered by the turrets thrown on July 12, 1961. In such a situation, areas that can be affected due to hurricanes are already warned. Many satellites of this continuous satellite are thrown out by measuring the temperature and determining the density of the electrons in space. After the tireless satellite, Jesus and then the breath of the satellites were thrown into space. Breath-2 satellites, thrown on May 15, 1966, measure the balance of the heat of the Earth. Sihs-1 provides search for hurricane data. To prevent the loss of life and property, weather satellites warn about hurricanes, floods and fire. Almost all satellite clouds receive photographs. By submitting the news on magnetic tape and then transmitting the telemetry directly to the computer stored in the ground station. The ability to reproduce the image of the clouds that are located on Earth during that time.

Clashes and landslides

On February 10, 2009, America's artificial satellite Iridium 33 and Russian Cosmos 2251 satellites were hit. The event happened on Siberia's 789 kilometers. NASA's satellite scientist Mark Matney told the MSSBC channel [7], that this was the first encounter of a fatal conflict of two satellites.

German satellites Rosetta was sent to space in 1990 to find the source of black hole, neutron star, x-ray etc. in space. However, due to gravity, it can hit anywhere in the world between 22 or 23 October 2011, according to a German space station DLR.

Use

People have launched many artificial satellites for different needs, especially in the use of communication for communication. Most television channels broadcast their shows through it. Besides, artificial satellites are used in internet connection, telephone connections, networking in flying airports, networking in remote areas, GPS connection and various activities.
