The 11 Largest Satellite Companies In The World, And What They Do

Satellites are remarkable pieces of technology that utilize planetary gravitational fields to move around a planet or another location reliably over time. Thousands of satellites are currently orbiting the earth and we rely on them for communication, monitoring, data tracking, and much more.

Without satellites, we wouldn’t have advanced utilities like GPS devices and we would have serious communication issues with remote devices. This is why each of the largest satellite companies is important to modern society in some way.

A variety of specialized companies work to make up the satellite infrastructure available today, and these companies don’t provide services to everyone.

Getting familiar with some of the largest satellite companies and what they do will help you come to appreciate their services and the technologies they make possible for you and everyone else you know. 

How Satellite Technology Works

Satellites are specialized communication devices that are launched up into the earth’s orbit at precise locations where they will continually move around the earth in a predictable manner. The satellites come equipped with solar panels and batteries for most of their power needs, as well as some reserve fuel for slight position adjustments as needed. 

Once a satellite is launched up into the proper area of earth’s orbit it continually rotates around the earth where ground stations can send signals up to the satellite and it can beam them down to other stations. Satellites serve as data transmission tools, and they can be used for remote monitoring of the earth and of space. 

Satellites transmit data through light beams for the fastest transmission times and they enable a huge range of different technologies to function properly. Without satellites, we wouldn’t have GPS, cell phone service in remote environments, reliable television broadcasting or effective weather prediction systems. Much of our most advanced data tracking and transmission technologies today rely on maintaining a cluster of satellites in orbit around the earth. 

The Largest Satellite Companies Cover the Earth with Just a Few Satellites

It’s possible to communicate around the world with between 3, 10, or 20 satellites depending on how far away from the earth they are positioned. Three satellites located in geosynchronous orbit or GEO satellites can communicate everywhere in the world.

10 medium earth orbit satellites can communicate around the world and 20 low earth orbit satellites can communicate everywhere. Coverage ranges get smaller when satellites are closer, but transmission speeds increase. This is why many data companies are relying on low earth orbit satellites to provide the fastest data transfers. 

#11: China Satellite Communications – $380M 2021 Revenue

This company is based in Beijing China and maintains 16 different geostationary satellites that supply communication to China, Southeast Asia, the Middle East, Africa, Europe, and South Asia.

The company leases satellite data connections and makes it possible for government agencies, media companies, air traffic, aviation networking businesses and more to all get the data streams they need to function properly. 

The company provides reliable data connections by maintaining satellite positions that remain largely unchanged and that stay with earth’s orbit over time. The company has more than 550 employees and is considered to be a private company that’s utilized by both private and public organizations. 

#10: The SpaceX Starlink Satellite Network – $500M 2021 Revenue

SpaceX is launching a huge number of low-orbit satellites up into low Earth orbit to deliver internet to users around the world. The satellite service is known as Starlink, and it is currently made of approximately 3,055 satellites that number is expected to rise dramatically over the coming years.

Starlink is designed to deliver internet across the world where reliable connections aren’t currently available and are working with certain cell phone providers to help reduce dead spots for more reliable texting and calling. 

#9: Korea Aerospace Research Institute – $583M 2021 Revenue

The KARI maintains a network of eight active satellites while striving to advance South Korea’s aeronautical and space technologies.

The company has been developing its own rockets since its start in 1989 and has crafted satellites, space vehicles, and more in its efforts to get on the Moon, achieve space exploration milestones and develop a network of regional satellites. 

The company is also working to develop its own GPS service to be known as the KPS to help aid communication efforts within the country. 

#8: Iridium Communications – $615M 2021 Revenue

Iridium Communications is a US-based company that maintains a system of 66 active satellites that all work together for communication purposes. This business also has 9 backup satellites for enhanced reliability.

The satellite network is made specifically to work with handheld satellite phones and other specialized transceivers. The network is essential for maintaining communication in different areas of the world. The company has since branched out to offer mobile WiFi hotspot services to customers and helps its customers share their location information with emergency service providers. 

The company got its name from Iridium, the chemical element because it has the atomic number 77. That’s the number of satellites the company was originally going to send up. 

#7: Kratos Defense and Security Solutions – $830M 2021 Revenue

Kratos Defense and Security Solutions is a U.S. defense engineering and development company that creates ground stations and ground software management systems. The company works to develop technologies used in drones, missiles, unmanned airplanes, and more. 

Kratos contracts with the US military to develop new technologies, and meet the supply needs of the government. The organization works to push technology forward for the country. Kratos doesn’t specialize in satellite production but works to develop accessories, stations, and software that enables organizations to communicate with satellites effectively. 

#6: China Spacesat Co – $1.01B 2021 Revenue

This company operates throughout North China, South China, and Northwest China. The company develops minisatellites and microsatellites. China Spacesat works to research and develops modern satellite technologies.

#1: Mitsubishi Electric – $37.9B 2021 Revenue

Mitsubishi Electric is a major organization in the satellite industry that manufactures satellites for companies around the world. The business is responsible for creating more than 600 satellites and works to create the hardware for satellite-based communication and observation. Mitsubishi is involved with the International Space Station and has worked on several projects producing and helping to manage Science Satellites.

Each of these satellite companies is a private organization and many of the companies work with the public sector to ensure government officials have reliable communication in harsh environments. Satellites enable impressive technologies, such as GPS tracking, reliable phone service in remote locations, and more. Without this technology, communication would be significantly impacted.

Fortunately, there are many providers working to give businesses and scientific organizations access to the satellites they need to conduct their research, communicate, and more. 

While Safran and Mitsubishi Electric both came in with more impressive revenue figures than SES, it’s important to note that each of these companies offers products and services that are unrelated to the satellite industry as well, while SES strictly focuses on satellite-based technologies.
