* International Space Station (ISS): Orbits at an altitude of about 250-400 miles (400-640 kilometers).

* Weather Satellites: Orbit at various altitudes, but generally range from 22,000 to 22,300 miles (35,400 to 35,800 kilometers) for geostationary satellites, which stay above the same point on Earth.

* GPS Satellites: Orbit at an altitude of about 12,550 miles (20,200 kilometers).

Therefore, the International Space Station is much closer to Earth than weather satellites and GPS satellites.
