Full Form of GEO
What is GEO?
Geostationary Earth Orbit (GEO) is a circular orbit approximately 35,786 kilometres above the Earth's equator. A satellite in GEO travels at the same rotational speed as the Earth, making it appear stationary relative to a fixed point on the ground. This unique property makes GEO satellites ideal for continuous communication, broadcasting, and meteorological monitoring. In India, the Indian Space Research Organisation (ISRO) uses GEO for its INSAT and GSAT satellite series, which provide television, telecommunication, and weather services across the country. GEO satellites are also crucial for defence surveillance and disaster management, enabling real-time data relay. Students and professionals in space technology, telecommunications, and earth sciences frequently encounter GEO in textbooks, competitive exams like UPSC, JEE, and GATE, and industry contexts. The orbit's high altitude, however, introduces latency in signals, which is a key consideration for two-way communications. Understanding GEO is essential for grasping satellite communication and remote sensing fundamentals.

GEO — frequently asked questions
What is the full form of GEO?
GEO stands for Geostationary Earth Orbit, a circular orbit at about 35,786 km above the equator where satellites appear stationary over a fixed point on Earth.
How is GEO different from LEO?
LEO (Low Earth Orbit) is much closer to Earth (200–2,000 km) and satellites move quickly, while GEO is at high altitude and satellites appear fixed, offering continuous coverage but with higher latency.
Why does ISRO use GEO satellites?
ISRO uses GEO for INSAT and GSAT satellites to provide uninterrupted telecommunications, television broadcasting, and weather monitoring across India, as a single GEO satellite can cover nearly one-third of the globe.
