Uses Of Polar Satellite
They were some of the very first satellites launched into space.
Uses of polar satellite. Polar instruments were used during the primary mission of the themis satellite between january and april for his study of magnetic tail. 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. So for standard visible and infrared the geostationary images are used for sectors. Data acquired by satellite borne radars were able to show sea levels have been rising by three mm a year over the last decade.
The changing sizes of the glaciers which is difficult to do from the ground due to the remoteness and darkness of the polar regions the satellites can determine the long term patterns of. 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. Polar imagery over a given area is much less frequent than geostationary imagery. Global navigation satellite system gnss types uses importance.
They are use for mapping and spying. 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.
Space weather sensing changes. 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. Here is an image of a typhoon taken from space. Satellites that study the weather make use of polar orbits.
A polar satellite is a satellite that travels around the earth passing over both poles with every orbit. Communications satellites e g. While the synchronous orbit is best for communication satellites lagrangian point orbits help monitor the solar wind before it reaches earth. You ll have seen the pictures they produce on the weather reports.
A type of scientific satellite that studies the earth s atmosphere. 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. 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. Satellites monitor ocean temperatures and prevailing currents.
