Which orbit type abbreviation is matched to "Medium Earth Orbit" in the material?

• A. GEO
• B. MEO
• C. LEO
• D. HEO

Answer: (B)

Medium Earth Orbit is abbreviated MEO. This category covers altitudes between the closer, lower orbits and the high geostationary belt, placing satellites at a mid-range height above the Earth. The orbital period is longer than that of a Low Earth Orbit satellite but shorter than a Geostationary Orbit satellite, which is why MEO is commonly used for systems that need broad coverage without the extremely high altitude of GEO. For context, GEO sits at about 35,786 km so a satellite there appears fixed over one longitude; LEO is much closer with about a 90-minute orbit; HEO refers to highly elliptical orbits with varying distance from the Earth. So the abbreviation for Medium Earth Orbit is MEO.
