What does MEO stand for?

• A. Moon Earth Orbit
• B. Medium Earth Orbit
• C. Multi-Earth Orbit
• D. Major Orbit

Answer: (B)

Abbreviations for satellite orbits are organized by altitude, and MEO designates a middle-altitude belt. The expansion is Medium Earth Orbit. This region lies above low Earth orbit and below geostationary orbit, roughly from 2,000 km up to about 35,786 km above the Earth's surface. This height offers a good balance: signals travel fast enough for timely communication, footprints cover larger areas, and launch energy stays reasonable. Navigation systems—GPS, Galileo, GLONASS—use MEO paths, typically around 20,000 km up, with orbital periods near 12 hours so a ground location sees satellites pass overhead regularly. The term Moon-Earth Orbit isn’t the standard designation for this Earth-centric orbital category, and other phrases like Multi-Earth Orbit or Major Orbit aren’t used to label this region.
