Full Form of LEO
What is LEO?
Low Earth Orbit (LEO) refers to an orbit around Earth with an altitude typically between 160 and 2,000 kilometers. It is the most accessible orbital regime for satellites, enabling Earth observation, communications, and scientific research. In India, LEO is critically important for the Indian Space Research Organisation (ISRO), which launches Earth observation, remote sensing, and communication satellites into this orbit. These satellites support weather monitoring, disaster management, agricultural planning, and telecommunication services across the country. LEO is also used for crewed missions; for instance, ISRO's Gaganyaan programme plans to place astronauts in a low Earth orbit. The orbit allows for shorter orbital periods, higher-resolution imaging, and lower launch costs compared to higher orbits like geostationary orbit. Students preparing for competitive exams like UPSC, SSC, and JEE may encounter LEO in topics related to space technology, satellite communication, and India's space missions. Understanding LEO is essential for grasping satellite dynamics and India's growing role in space exploration.

Example
ISRO's EOS-04 Earth observation satellite was successfully placed into a polar low Earth orbit (LEO) to provide high-resolution images for agricultural and forestry applications.
LEO — frequently asked questions
What is the full form of LEO?
The full form of LEO is Low Earth Orbit, an orbital region between 160 and 2,000 kilometers above Earth's surface.
How does ISRO use LEO for satellites?
ISRO launches Earth observation, remote sensing, and communication satellites into LEO to monitor weather, agriculture, and disasters, and to provide connectivity.
What is the difference between LEO and GEO orbits?
LEO is closer to Earth (160-2,000 km) with shorter orbital periods, while GEO (Geostationary Earth Orbit) is at about 36,000 km and remains fixed over a location.
