Artificial satellites are still used today for communications purposes. Satellite is no longer used for normal smartphone communication. But smartphone GPS mapping of the smartphone is available on satellite. Satellites are widely used for television communications, networking to isolated areas, and for collecting meteorological data. There are already many satellites in different orbits above the globe. Let’s look at what these satellites are and their functions.
1. Advantages of Satellites
It is easy to use satellite for broadcasting. This means that satellite technology makes it easy to exchange TV signals properly. The satellite can cover the whole world. Therefore, the satellite is used for mapping and for obtaining weather data. Satellite communication is available in the Amazon, in the middle of the Sahara, and in the distant Antarctic. Although there are obstacles in the land, mountains, deserts, water bodies, etc., nothing interferes with the communication through satellite.
2. Limitations of Satellite Technology
When it comes to technology in Sri Lanka, we still regret that we haven’t even been able to send a satellite. With the development of rocket technology, India has been able to fly satellite technology. Satellite technology is a bit overused. It also costs a considerable amount of money to fly a satellite. Also, satellite communications are blocked by clouds. When the satellite is on the air, there may be problems with the mixing of these signals.
3. Satellite Types By Height
There are geostationary satellites in orbit about 35,900 km above the earth. Somewhere above the satellites are located throughout the year. Due to some factors, these satellites have the means to return to their original position and serve. Below that, there’s another mid-range satellite. It also contributes to satellite imagery and other communications in the lower orbit. Satellites that do not have geoengineers rotate around the earth. Therefore, when collecting data from such satellites, a number of satellites take flight and collect data from them.
4. New Data Transfer Trends in Satellite Technology
So far, communication has been carried out over seven or eight thousand kilometers or through geostationary satellites. But the higher the Earth’s orbit, the greater. Simply put, radio communications are thousands of kilometers away in the air, and our communications take a considerable amount of time. So it was not very practical to connect the satellite to the internet. However, many satellites within the range of 800-1500 km above the globe have theoretically been able to transmit data faster than the world’s fastest long-range communication medium, Optical Fiber. Last year, SpaceX, including Elon Musk, did some research on this.
5. Satellite Why Gold and Silver?
Satellite images in the sky often show gold or silver. This is because the Earth wants to withstand the intense solar rays of high orbits. Because the Earth is in high orbits, this satellite is exposed to the sun most of the day. Also, these satellites will have to face some solar rays from the sun. Therefore, a satellite is covered with a shiny shield to protect valuable communication systems.
6. How To Get Power?
The satellite is basically powered by solar panels. Once a satellite is installed in the sky, it can’t be repaired as frequently as something on the ground. So when a satellite is launched, all the relevant systems are processed and sent from Earth. The energy from these solar panels and solar panels is stored in the batteries, and the satellite power system works in the dark areas of the earth. Also, the satellite’s antennas are used to power the satellite in order to maintain the proper orbit and reduce the possibility of collision with other satellites if modern.
7. Internet And Satellite To New Events
Satellite technology needs to be improved to provide faster Internet services on navigation and aviation. Also, satellite map mapping and meteorological data have been improved. Although the satellite launched from our country is rare, we are mapping the phone via satellite. Indoor television viewers are also able to capture clear images via satellite. Satellite use is not possible at this time of the Internet, but future research on the satellite will help the Internet cover every corner of the globe.
Arthur C. Clarke is a sea explorer. A talented diver, Arthur C. Clarke loved the sea and Sri Lanka. As early as 1945, Arthur C. Clarke had commented on the use of satellite communications, which was not as popular as satellite technology. The whole world can be covered by three satellites
