What is a key characteristic of Low Earth Orbit (LEO)?

• A. Orbital period of 24 hours
• B. Altitude of 200-900 miles
• C. Used primarily for GPS communication
• D. Maintains a static position relative to the Earth

Answer: (B)

A key characteristic of Low Earth Orbit (LEO) is its altitude range, which typically spans from approximately 200 to 900 miles above the Earth's surface. This altitude range allows satellites in LEO to have lower latency and higher resolution for imaging and communication compared to those in higher orbits. The proximity to Earth facilitates various applications, such as Earth observation, reconnaissance, and communications, making LEO suitable for a broad spectrum of satellite missions. The specifics of the altitude are crucial for understanding the operational advantages of LEO, such as shorter transmission times for signals and the ability to capture high-resolution imagery. This makes LEO increasingly popular for a variety of emerging technologies, including large constellations of satellites designed for global internet coverage. Other attributes often associated with LEO, like its orbital period of approximately 90 to 120 minutes and the lack of a static position, further distinguish it from other orbital categories. Understanding LEO's altitude is fundamental for grasping its characteristics and the capabilities of satellites deployed in this region.
