This inclination is a compromise that provides optimal coverage for the primary users of the facility while managing launch constraints from equatorial sites. The Role of Inclination In addition to altitude, the orbital inclination—the angle between the orbital plane and Earth’s equator—defines the specific characteristics of a low Earth orbit.
International Space Station Orbit Altitude and Inclination
This phenomenon, known as orbital decay, is a primary operational concern for objects in low Earth orbit. This high velocity is the defining characteristic that separates orbital mechanics from suborbital flight, which follows a ballistic arc and returns to Earth within minutes.
The region generally spans from 160 kilometers (100 miles) to 2,000 kilometers (1,200 miles) above mean sea level. The upper limit of 2,000 kilometers is not a strict physical barrier but a practical demarcation where the influence of Earth’s magnetosphere begins to interact more strongly with the space environment, and where orbital perturbations from the Moon and Sun become more pronounced.
International Space Station Orbit Altitude and Inclination
Low Earth orbit represents the closest region of space to Earth's surface, serving as the operational domain for the International Space Station, the Hubble Space Telescope, and thousands of active satellites. The reduced distance enables lower latency for communication signals, making it ideal for applications requiring real-time data transmission, such as video conferencing and remote control of systems.
