We cannot envision a world without interpersonal contact. So, connecting is necessary for information to be shared and alternative ideas to be adopted. An American writer named "Edward Everett Hale" wrote a piece published in the Atlantic Monthly from 1869 to 1870. He was the first to speak about satellite communication systems.
However, a Royal Air Force man named Arthur C. Clarke developed the first workable concept and presented it in a paper called 'Extra-Terrestrial Relays.' The first artificial satellite, known as Sputnik 1, was launched by the Soviet Union on October 4, 1957. This was the main space communication system with a diameter of 58 centimetres.
The Soviet Union gained international notice by launching Sputnik 1.
To better understand satellite communication, consider how readily you can watch the FIFA World Cup on your television. . Thus, for better understanding, we'll look at this definition and its working principles, types, and so on.
Well, satellite communication is a type of wireless communication that employs artificial satellites to communicate. Internet, voice, TV, video calling, fax, radio channels, and other services are available through this mode of communication. Also, communication over large distances is possible with this, and it may be used in circumstances and conditions that are permanent for other types of communication.
Furthermore, the artificial satellite may be put in orbit to communicate between different spots on the globe.
The data flow from one sender to a recipient who responds can be regarded as communication. Communication in layman's language is achievable by employing it as a channel between sender and recipient. Once the receiver receives the signals from the transmitter, it decodes and sends them back to the sender to enable communication. Communication can be accomplished through light in an optical communication system, radio waves in a radio communication system, and telephony in a satellite communication system. The purpose of this article is to provide an overview of the satellite communication system.
Communication satellites are similar to space mirrors that let us bounce communications such as internet data, television, and radio from one side of the world to the other. It consists of three steps that might assist in explaining how it works:
Consider the following example of television signals. The signal from the television broadcast on the opposite side of the world is first beamed up to the satellite from the earth's ground station in the first step. This is referred to as uplink.
Transponders like amplifiers, radio receivers, and transmitters comprise the second stage. These transponders are leveraged to enhance the incoming signal and to change its frequency. This helps to ensure that the outgoing signals are not tampered with. The transponders differ based on the signal sources.
The third step includes a downlink that transfers data to the other end of the receiver on Earth. It is critical to remember that there is usually one uplink and several downlinks.
You are aware that there are several modes of communication and that the propagation of these waves may occur in various ways. Skywave and Ground wave propagation are the two modes of communication for a given distance. The greatest distance they can go is 1500 km, which was surpassed when we invented satellite communication.
Interestingly, the Indian National Satellite (INSAT) system is one of the largest domestic communication networks in geostationary orbit. We have over 200 transponders in the INSTA system that we employ for a variety of reasons.
Telecommunications, weather forecasting, disaster warning, television transmission, search and rescue operations, and satellite news gathering all fall under this category. From 2002 through 2020, several satellites were launched. The first was KALPANA-1 in 2002, which stood for communication, climate, and environment. GSAT-30, a communication satellite, was launched in January 2020.
As previously stated, satellite communication is employed in various industries, including broadcasting, telecommunications, and military applications.
Here is a list of significant communications satellites that have accomplished remarkable accomplishments:
Satellite communication services are classified as mobile satellite, broadcast satellite, and fixed satellite services, based on the service out forward:
Depending on the requirements, several frequencies are utilised for satellite communications. The following are frequent ranges:
Let's have a look at the benefits and drawbacks of satellite communication in this part.
The following are some of the benefits of employing satellite communication:
The following are some of the drawbacks of employing satellite communication:
So, this was all you needed to know about satellite communication systems. Today, communication satellites are more important than ever as people are becoming more reliant on digital services.
