📜 Etymology

From Greek geo (γῆ, "earth") + stationary (from Latin stationarius, "standing still"); the concept was popularised by science fiction writer Arthur C. Clarke in the 1940s; the first geostationary satellite was launched in 1963; India's GSAT and INSAT communication satellites operate in this orbit.

🧠 Memory Hook

"Geo" (Earth) + "stationary" (standing still): a satellite that hovers stationary over one spot of the Earth, like a kite tied to a fixed point in the sky.
