Orbital Dynamics (GEO vs LEO): Geosynchronous Orbit (GEO) orbits at ~35,786 km matching Earth's rotation period, providing constant coverage over a given region, whereas Low Earth Orbit (LEO) operates at 160-2000 km with short orbital periods.
GSLV Launch Vehicle Class: GSLV is a three-stage launch vehicle utilizing solid, liquid, and indigenous Cryogenic Upper Stage (CUS) engines designed to place heavy communication and observation payloads into higher transfer orbits.
