Full Form of NGSO
What is NGSO?
NGSO refers to Non-Geostationary Satellite Orbit, a category of satellite orbits that includes Low Earth Orbit (LEO) and Medium Earth Orbit (MEO). Unlike geostationary satellites that remain fixed relative to Earth at around 36,000 km altitude, NGSO satellites orbit at much lower altitudes, typically between 500 and 2,000 km, and move across the sky relative to a ground observer. In India, NGSO systems have gained significant importance with the entry of global broadband constellations such as OneWeb and Starlink, prompting the Department of Telecommunications and ISRO to develop fresh frameworks for spectrum allocation, landing rights, and orbital coordination. NGSO satellites are primarily used to deliver global broadband internet, Earth observation services, and IoT connectivity, especially in remote, hilly, and rural regions where terrestrial fibre and mobile towers are difficult to deploy. The Indian National Space Promotion and Authorisation Centre (IN-SPACe) is also actively involved in authorising NGSO missions. For aspirants preparing for UPSC, GATE, and other competitive technical examinations, understanding NGSO concepts is essential within topics covering satellite communication, spectrum policy, and India's evolving digital infrastructure.

The Department of Telecommunications has been finalising new spectrum allocation norms for NGSO operators planning to offer satellite-based broadband services across rural India.
NGSO — frequently asked questions
What is the full form of NGSO?
NGSO stands for Non-Geostationary Satellite Orbit, referring to satellites that orbit Earth at altitudes lower than the geostationary belt of 36,000 km.
What is the difference between NGSO and GEO satellites?
GEO satellites orbit at around 36,000 km and appear stationary from the ground, while NGSO satellites orbit much lower and continuously move relative to the Earth's surface, requiring constellations for continuous coverage.
Why are NGSO satellites important for India?
NGSO satellites are important for India because they can deliver high-speed broadband internet to remote, rural, and hilly regions where laying optical fibre or building terrestrial towers is difficult and expensive.
