Satellites are primarily found in the thermosphere, which is the layer of the Earth's atmosphere located approximately 80 to 600 kilometers (50 to 370 miles) above the surface. Some satellites, especially those in low Earth orbit (LEO), operate within the lower part of the thermosphere, while others, like geostationary satellites, are positioned in the exosphere, which extends above the thermosphere. These layers provide the necessary altitude for satellites to maintain their orbits and avoid significant atmospheric drag.
Satellites are located in the exosphere because it is the outermost layer of Earth's atmosphere and provides an ideal environment for satellites to orbit without encountering significant atmospheric drag. This allows satellites to continuously orbit the Earth and perform their intended functions, such as communication, Earth observation, and navigation.
The troposphere is the closest to the Earth and most dense atmospheric layer

Atmospheric studies satellites were some of the very first satellites launched into space. They generally have pretty low Earth orbits. they are used to study the Earth'satmosphere. 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). With the help of Atmospheric Studies Satellite 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.
Orbiting satellites are typically found in the thermosphere layer of the atmosphere, which extends from about 80 to 600 kilometers above the Earth's surface. This layer is where the density of gas molecules is low enough for satellites to orbit without experiencing significant atmospheric drag.

The Exosphere is the atmospheric layer the farthest distance from the lithosphere.

If they are in the atmosphere (low earth orbit), satellites are in the ionosphere. If they are in higher orbits, satellites are considered to be outside the atmosphere.

Do all planets and satellites lie on the same gravitational layer?
ionosphere
The atmospheric layer containing pollution is troposphere. It the nearest to earth.
Thermosphere and the exosphere
The outermost and biggest layer of Earth's atmosphere is the exosphere. This layer extends from about 500 to 10,000 kilometers above the Earth's surface and gradually transitions into outer space. The exosphere is where satellites orbit and where atmospheric particles are very sparse.
