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.
