type of satellite and their function.
(any 3).
Answers
Answer:
1.Astronomy satellite: an astronomy satellite is basically a really big telescope floating in space. Because it is in orbit above the Earth, the satellite's vision is not clouded by the gases that make up the Earth's atmosphere, and its infrared imaging equipment is not confused by the heat of the Earth. Astronomy satellites, therefore, can "see" into space up to ten times better than a telescope of similar strength on Earth. Can you guess what kinds of things an astronomy satellite would be looking at?
These are some pictures taken by the astronomy satellite Hubble of stellar phenomena like supernovas, distant galaxies, black holes, and quasars:
2.Atmospheric studies satellites: Atmospheric studies satellites were some of the very first satellites launched into space. They generally have pretty low Earth orbits so that they can study the Earth's atmosphere.
Alouette, the first satellite launched by Canada, was also the world's first atmospheric studies satellite. The purpose of Alouette was to study the Earth's ionosphere (a charged layer of the atmosphere). Canadian scientists were trying to learn more about the aurora borealis, or northern lights - disturbances of the ionosphere in the atmosphere which create brilliant lights in the northern skies at night, but disturb radio communications.
3.Navigation Satellites: Satellites for navigation were developed in the late 1950's as a direct result of ships needing to know exactly where they were at any given time. In the middle of the ocean or out of sight of land, you can't find out your position accurately just by looking out the window.
The idea of using satellites for navigation began with the launch of Sputnik 1 on October 4, 1957. Scientists at Johns Hopkins University's Applied Physics Laboratory monitored that satellite. They noticed that when the transmitted radio frequency was plotted on a graph, a pattern developed. This pattern was recognizable to scientists, and it is known as the doppler effect. The doppler effect is an apparent change of radio frequency as something that emits a signal in the form of waves passes by. Since the satellite was emitting a signal, scientists were able to show that the doppler curve described the orbit of the satellite.
Today, most navigation systems use time and distance to determine location.
Answer:
Satellites can be classified by their function since they are launched into space to do a specific job. ... There are nine different types of satellites i.e. Communications Satellite, Remote Sensing Satellite, Navigation Satellite, LEO, MEO, HEO, GPS, GEOs, Drone Satellite, Ground Satellite, Polar Satellite.
