How long do Starlink satellites stay in orbit? Starlink satellites are designed to stay in the air for about five years. As the satellites reach their end-of-service date, they’ll be steered into the Earth’s atmosphere, where they’ll burn up. Why do astronomers have a problem with Sta...

How Many Russian Earth Observation Satellites will be in Orbit by 2015?Space Daily
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?
satellites are geostationary. Some have elliptical orbits, which means they drift east and west over a fixed point on the surface during the course of a full orbit. Some have orbits that are not aligned with Earth’s equator. These orbital paths are said to have degrees ofinclination. It ...
Since these satellites continuously orbit Earth (circling two times per day), data acquisition and application has dramatically sped up. This allows map-makers to create the most up-to-the-minute maps, especially important as land planning and environmental impact have become such hot-button issues...
When people talk about "a GPS," they usually mean a GPS receiver, but the Global Positioning System (GPS) is actually a constellation of many Earth-orbiting satellites (gps.gov/systems/gps/space/">31 in operational orbit and four that are classified as either "in reserve" or "unhealthy...
So, what makes China's BDS stand out among its competitors? Firstly, the other systems have 24 satellites in medium earth orbit (MEO). In addition to the 24 satellites, the BDS constellation also has three satellites in geostationary earth orbit (GEO) and three in inclined...
How Does Satellite Internet Work? As the name implies,satellite internetuses satellites orbiting the Earth to provide internet access, particularly in remote or rural areas where traditional wired connections are unavailable. The process begins with an ISP sending data to a satellite in geostationary ...
Like acell phone, aGPS receiverrelies on radio waves. But instead of using towers on the ground, it communicates with satellites that orbit the Earth. There are currently 27 GPS satellites in orbit -- 24 are in active use and 3 act as a backup in case another satellite fails. ...
