LEO
Low Earth Orbit (LEO) is the region of space closest to Earth, where most Earth observation and communication satellites — including Lemu Nge — operate.
Low Earth Orbit
LEO refers to an orbit around Earth with an altitude typically between 160 km and 2,000 km. Satellites in LEO complete an orbit in roughly 90–120 minutes. Because of the proximity to Earth, LEO provides high-resolution imaging, lower latency in communications, and faster revisit times compared to higher orbits such as Medium Earth Orbit (MEO) or Geostationary Orbit (GEO).

Relationship to Lemu
Lemu Nge, the world’s first biodiversity-focused hyperspectral satellite, operates in LEO to capture high-resolution spectral data of ecosystems. LEO enables Lemu to achieve frequent revisit times and precise monitoring of biodiversity dynamics.
