Satellites need to take accurate measurements while orbiting without any wobbling. Therefore, they are regularly stabilized through a process known as attitude control. Gyroscopic motion is utilized to stabilize
Thousands of satellites fly overhead every day, helping us with things like weather forecasts, scientific research, communications, TV broadcasts (and maybe some surreptitious spying). How much do you know about these eyes in the sky?
much of Earth passes under a satellite in a polar orbit. Because polar orbits achieve excellent coverage of the planet, they are often used for satellites that do mapping and photography. And weather forecasters rely on a worldwide network of polar satellites, which covers the entire globe ever...
In the more than five decades following the launch of Sputnik, satellites, as well as their budgets, have tended to get bigger. The United States, for example, has spent $200 billion on its military satellite program since its inception and now, despite the investment, has a fleet of aging...
A GPS receiver uses these satellites to calculate the precise location of the person operating the device. How Does GPS Work? GPS receivers work by locating four or more of these satellites, figuring out the distance to each, and using this information to deduce their own location. This ...

Electrons circle the nucleus in fixed orbits -- a simplified way to think about it is to imagine how satellites orbit the Earth. There's a huge amount of theory around electron orbitals, but to understand light there is just one key fact to understand: An electron has a natural orbit that...
Types Of Satellites In Space Today There are thousands of satellites in space circling the earth right now. But how do they stay in orbit and not collide with one another? They reside within different orbits. There are actually three types of orbits they can be in; high earth orbit, medium...
Satellite technology has advanced exponentially over time. Some companies have even promised to transform the way satellites work. The goal is to give a large population access to reliable Internet so that residents can have more choices.
