LEO, MEO, GEO - Comparing Earth's Orbits - Lesson 2.4

Explore the fundamental differences between Low Earth Orbit (LEO), Medium Earth Orbit (MEO), and Geosynchronous Earth Orbit (GEO) in this 12-minute educational video from Yale University's rocket science course. Compare satellite populations and primary functions across these three orbital regions while analyzing how altitude affects Earth imaging capabilities, including field of view and resolution considerations. Examine the concept of latency in satellite communication and understand its significance for different orbital altitudes. Learn about the distinct end-of-life procedures required for satellites in each orbital region and discover how mission-specific goals determine optimal orbital placement. Gain insights into the distribution of satellites within each orbit and understand why certain orbits are preferred for Earth observation versus communication purposes, with particular attention to the trade-offs between coverage area, image resolution, and signal delay that influence satellite deployment decisions.
