Satellites are used for many different purposes, from transmitting GPS information to providing rural areas with internet access. Satellite internet has been increasing in popularity as people realize its many benefits. People who live in underserviced or rural locations can benefit greatly from satellite internet since it can reach almost any place on Earth and provide a fast and reliable connection.
Satellite Positioning and NOC
It’s not difficult to understand how satellite internet works even though the technology used is complicated. Special satellites known as geostationary satellites are used to give people internet access. They orbit the Earth and appear as if they never move. This is because these satellites orbit the Earth as fast as the Earth rotates. Since their orbit and the Earth’s rotation is the same speed, they look like a fixed point in the sky. Geostationary satellites are approximately 22,000 miles above the Earth.
The NOC is known as the network operations center. This is a special location on the Earth that is connected to the internet. The geostationary satellite receives and sends information to and from this location. Then, the satellite will send information to a dish that is installed at a person’s home. Information will be sent to and from the NOC, the geostationary satellite, and the dish installed at a person’s house. Once information is sent to the dish, it will then travel to the modems that are installed in a person’s home. These modems can be connected to routers that allow people to use computers, laptops, smartphones, and other mobile devices.
An Unobstructed View
In order for satellite internet to properly work, the area where the dish is installed needs to have a clear and unobstructed view of the south. If the view is obstructed, then the satellite will not be able to send and receive data. Some people find that they have to cut down a tree or move something so that their satellite internet connection will work.
One problem that satellite internet has to deal with is latency. Latency is a small delay that happens when information is sent. For example, if a person accesses a website or downloads a song, then they will have to wait about half a second before the site or music starts downloading. This is because it takes the information a while to reach the satellite and then reach the NOC back down on Earth. In fact, the information that is sent must travel the 20,000-mile distance four times.
Even though a half of a second does not seem like a very long amount of time, it can cause problems with people trying to play video games online or doing another real-time activity. Other activities such as downloading music or surfing the web won’t be a problem at all. People will barely notice a half-second delay while doing these activities.
When people have satellite internet installed, they have to have two separate modems. One modem is used for downloads, while the other is used for uploads. Satellite uploads are significantly slower than downloads.
People who live in a rural area or in any area that is underserviced should refer www.satellitestarinternet.com/ for satellite internet. The download speeds are a lot faster than dial-up, and the satellites that are used are reliable.
