Earth satellites are typically placed in orbit above the Earth's atmosphere because the atmosphere would cause drag on the satellite and weaken its orbit. Being above the atmosphere also allows for clearer communication signals between the satellite and Earth. The gravitational field of the Earth extends far beyond the atmosphere, so being above it is not the main reason for the high altitude of satellites.
