Explore Medium Earth Orbit (MEO) and discover how GPS satellites navigate the challenging space between 2,000 and 35,000 km above Earth in this 12-minute educational video from Yale University's rocket science course. Learn why GPS satellites operate specifically at 20,000 km altitude despite the hazardous Van Allen Belts, and understand the precise timing and triangulation mechanisms that enable your phone to determine your exact location anywhere on Earth. Examine the characteristics and unique challenges of MEO compared to other orbital regions, and discover why this orbit provides the optimal balance for global positioning systems. Investigate how GPS satellites use atomic clocks and mathematical triangulation to pinpoint locations with remarkable accuracy, and explore the global dependence on this critical technology for navigation, transportation, and countless daily applications. Gain insight into international satellite navigation systems beyond GPS and understand the broader implications of MEO satellite technology for modern civilization.
