Weather Satellite: Facts and Information –
There are many satellites in outer space that have different functions. Some are used for communication by the army and by regular people, some are used to take pictures of the earth, and then there are those that help us collect data about the weather. No matter what their purpose, satellites play an important role in collecting and distributing data collected about the earth. Many countries will work together to put satellites into the earth’s orbit so that they all can benefit from it being there.
Satellites whose position remains the same relative to a spot on earth are known geostationary satellites. They hover over the equator at a height of 35,900 kms above the surface. They fly west to east at the exact speed of the orbit of the earth. This way they are constantly able to survey a large portion of the surface.
Polar orbits, on the other hand travel in orbits from north to south to fill in the gaps that geostationary equatorial satellites cannot cover. Weather satellites provide vital information about cloud patterns and ground and sea temperatures. They collect and share information with remote data collecting stations such as weather buoys, and observatories from around the world. All this information is send to a communications center on earth that in turn distributes it to whoever needs or wants it.
Can you find out what satellites that do not follow a fixed orbit around the earth are called? What are some of their uses?
