Uses Of Polar Satellite

So for standard visible and infrared the geostationary images are used for sectors.

Uses of polar satellite.

While the synchronous orbit is best for communication satellites lagrangian point orbits help monitor the solar wind before it reaches earth. Polar instruments were used during the primary mission of the themis satellite between january and april for his study of magnetic tail. Polar mapped mosaic satellite composite images are used for daily snapshots of the entire northern hemisphere southern hemisphere or a mercator projection view of the tropics. Imaging satellites can measure the changing sizes of glaciers which is difficult to do from the ground due to the remoteness and darkness of the polar regions.

They can also give early warnings of severe weather and make measurements of the earth s atmosphere. Satellites monitor ocean temperatures and prevailing currents. Polar orbiting operational environmental satellites and eumetsat are used for more than just sensing cloud cover or how cold high cloud tops are colder cloud tops indicate strong or severe convection. Communications satellites e g.

Global navigation satellite system gnss types uses importance. A low altitude polar orbit is widely used for monitoring the earth because each day as the earth rotates below it the entire surface is covered. A polar satellite is a satellite that travels around the earth passing over both poles with every orbit. 1 a time lapse animation of aurorae over both earth poles shows symmetries and simultaneous changes the long suspected aurora mirroring in images from the visible imaging system vis.

Satellites that study the weather make use of polar orbits. Space weather sensing changes. Here is an image of a typhoon taken from space. Satellites are used for many things such as communication.

They are use for mapping and spying. A type of scientific satellite that studies the earth s atmosphere. Polar imagery over a given area is much less frequent than geostationary imagery. They were some of the very first satellites launched into space.

Below is a depiction of the orbit of a polar orbiting satellite. One such weather satellite is called noaa 17. Different types of satellite orbits have different uses. Data acquired by satellite borne radars were able to show sea levels have been rising by three mm a year over the last decade.

A type of satellite used for communications on earth by allowing radio television and telephone transmissions to be sent live anywhere in the world.
