Big or small, future satellites must be able to communicate efficiently with Earth-based stations. Historically, NASA has relied onradiofrequency (RF) communication, but RF is reaching its limit as demand for more capacity increases. To overcome this obstacle, NASA scientists have been developing a...
Satellite Communication System: How Does It Work? Communication satellites are similar to space mirrors that let us bounce communications such as internet data, television, and radio from one side of the world to the other. It consists of three steps that might assist in explaining how it works...
In addition to the ionosphere, satellites can also communicate with each other using a space satellite. These satellites act as mirrors, reflecting signals towards the receiving satellite. They also amplify and re-transmit signals, which can be weakened due to dissipation and absorption in the atmos...
The Hubble Space Telescope is deployed from the cargo bay of the space shuttle Have you ever stared at the night sky and wondered what the universe looks like up close? Even if you're lucky enough to have access to a ground-based telescope, whose clarity depends on atmospheric factors ...
A detailed guide on how a small satellite dish on Earth communicates with geostationary satellites orbiting 22,300 miles above the equator.
For more details on these devices, check out How Spy Gadgets Work. There are numerous technological ways for countries to spy on each other without ever sending an actual spy to collect information. Satellites equipped with cameras have been tracking the positions of military units since the 1960...
Satellites circling Mars could help send information back to Earth over an interplanetary Internet. You can talk to almost anyone, in any corner of the world, almost instantly because of the Internet and other advances in electronic communication. Scientists and space explorers now are looking for ...
It has been debated that communication using fiber optics is more reliable than satellites and is less prone to errors. Yet, the terrestrial nature of the services from fiber internet providers means they can become damaged as cables can be cut accidentally or damaged through ...
Satellite internet is a type of internet connection that utilizes communication satellites stationed in space to transmit and receive data signals. Unlike traditional broadband connections that rely on physical cables, satellite internet bypasses the need for wired infrastructure by beaming data to and fro...
