// ORBITAL LOGISTICS AND PROPULSION TERM
MEO
MEO stands for Medium Earth Orbit, which is a region of space between low Earth orbit (LEO) and geostationary orbit (GEO), typically used by navigation satellites like GPS.
TECHNICAL DEFINITION
Medium Earth Orbit (MEO) is an Earth-centric orbital regime situated between 2,000 km and 35,786 km altitude, commonly utilized by navigation satellite systems (e.g., GPS, Galileo) and some communications constellations due to its balance of coverage and latency.
BACKGROUND
Space-based solar power is the concept of collecting solar power in outer space with solar power satellites (SPS) and distributing it to Earth. Its advantages include a higher collection of energy due to the lack of reflection and absorption by the atmosphere, the possibility of very little night, and a better ability to orient to face the Sun. Space-based solar power systems convert sunlight to some other form of energy which can be transmitted through the atmosphere to receivers on the Earth's surface.

USAGE NOTE
Critical for global navigation satellite systems (GNSS) providing positioning, navigation, and timing services.
DEVELOPERS
