Satellites have become an integral part of modern life. From GPS navigation to weather forecasting, from television broadcasting to internet communication, Satellites have revolutionized the way we live and interact with each other. And with the advent of newer technologies, the day is not far when communication satellites will become an indispensable part of human life. With this in mind, let’s take a look at the current state of communication satellites and where things are headed.


Ethiopia, one of the fastest-growing economies in Africa, is planning to acquire a communication satellite through Ethio Telecom, the country’s telecom regulator. The project is aimed at improving the country’s telecommunications infrastructure, connecting rural areas, and creating a more competitive market with existing players.

The satellite, named “Ethosat,” is expected to be operational by 2020 and will cover the entire African continent and parts of Europe, Asia, and the Middle East. It will provide high-speed internet, telephony, and TV broadcasting services to millions of people in rural and remote areas who currently have limited or no access to these services. With the launch of Ethosat, Ethiopia could become a major player in the Satellite Communications industry in Africa.

RSCC enters TOP-15 world's biggest satellite operatorsThe Rise of Russian Satellite Operators

While the US, China, and Europe have traditionally dominated the satellite market, in recent years, Russian satellite operators have emerged as significant players in the industry. According to a recent report by Euroconsult, the Russian Satellite Communications Company (RSCC) has entered the top 15 largest satellite operators in the world.

The RSCC currently operates 12 communications satellites and plans to launch 10 additional ones in the next five years. With this expansion, the company aims to become one of the leading providers of satellite broadband services, particularly to remote and rural areas in Russia and neighboring countries.

Russian satellite operators are not only focusing on broadband communications but also on navigation and Earth Observation (EO) systems. The Russian Global Navigation Satellite System (GLONASS) is an alternative to the American GPS, and it is regarded as superior in terms of accuracy and signal strength. It is already being used by the Russian military and is being marketed to other countries as well.

Space Technology: Satellites And Orbits - UPSC (Notes)The Future of Satellite Communications

The future of satellite communication is exciting and promising, with technological advancements opening up new opportunities and possibilities. One such advancement is the development of Low Earth Orbit (LEO) satellites, which are capable of providing high-speed internet and other communication services with lower latency and higher bandwidth compared to traditional Geostationary Earth Orbit (GEO) satellites.

LEO satellites are positioned much closer to the Earth’s surface, typically at an altitude of 1,200 Km, as compared to GEO satellites, which are positioned at an altitude of 35,000 Km. This closer positioning significantly reduces the latency in data transmission and allows for higher bandwidth.

Another significant development in satellite technology is the rise of small satellites, also known as CubeSats. These are miniature versions of traditional satellites and are much cheaper to manufacture and launch. They have opened up new possibilities for research, applications in Earth Observation, and providing affordable internet services to remote areas. In fact, companies like SpaceX and OneWeb are already planning to launch thousands of these SmallSats to provide global internet coverage.

Another possibility is the use of satellites for interplanetary communication. With the increasing number of space missions to Mars and other planets, the need for interplanetary communication systems is becoming more apparent. NASA’s Mars Reconnaissance Orbiter, for example, has been providing communication services between Mars rovers and Earth since 2006.

Communications satellite - WikipediaFAQs on Communications Satellites

Q. How do communication satellites work?

Communication satellites work by receiving signals from transmitters on the ground, amplifying them, and retransmitting them to receivers on Earth. They are placed in orbit around the Earth so that they stay in the same position relative to the ground. This is accomplished by placing them in Geostationary Earth Orbit, which is a circular orbit 35,786 kilometers above the Earth’s equator.

Q. How long do satellites last?

The lifespan of a satellite depends on several factors, such as the altitude at which it is placed in orbit, the quality of the materials used to build it, and the conditions it is exposed to in space. Typically, most communication satellites have a lifespan of about 15 years, after which they need to be replaced with new ones.


The future of satellite communications is looking bright, with new technologies and innovative solutions opening up new possibilities and opportunities. From providing high-speed internet services to remote areas to interplanetary communication, communication satellites are revolutionizing the way we live and communicate. As we look forward to newer and more sophisticated satellites, it is essential that we ensure that their benefits are accessible to all, including those in rural and remote areas where connectivity is still a challenge.
