How do communications satellites work? What do they do? Communications satellites are "space mirrors" that can help us bounce radio, TV, Internet data, and other kinds of information from one side of Earth to the other. Uplinks and downlinks If you want to send something like a TV ...
Of course, launching and operating satellites leads to problems. Today, with more than 1,000 operational satellites in orbit around Earth, our immediate cosmic neighborhood has become busier than a big city rush hour [source:Cain]. And then there's the discarded equipment, abandoned satellites, ...

Navigation satellites, like the kind used by your car's GPS, work well at this altitude. Sample specs for such a satellite might be an altitude of miles (20,200 kilometers) and an orbital speed of 8,637 mph (13,900 kph). Finally, it's possible to think about satellites in terms ...

Devices that use GPS data Garmin and Magellan are two manufacturers of GPS devices. These devices come in various sizes and support numerous applications. Software built into each device links to GPS satellites and converts GPS data into visual images or audio messages to identify the shortest or...
But despite how ubiquitous GPS has become, and how essential it is for so many technologies we’ve come to take for granted, I realized that I couldn't answer, how does GPS work? At a high level, I thought I understood how GPS works. Satellites transmit their location, and by using ...
GPS operates using more than 30 satellites.(Image credit: Getty) Space.com: Before GPS was launched, what did you think the most beneficial application would be? Parkinson:I knew that the Air Force in World War II had to do, in essence, carpet bombing. What was called "precision weapon ...
Ground stations– ground stations are placed at known locations around the globe. Like the GPS receivers, these stations also receive the signals sent from the satellites. Because the stations already know their location, they are able to spot and calculate inaccuracies in the GPS signal and then...
How Does GPS Work? What is GPS? Global Positioning System (GPS) is a worldwide radio-navigation system formed from the constellation of 24 satellites and their ground stations. The Global Positioning System is mainly funded and controlled by theU.S Department of Defense(DOD). The system was ...
