What you’ll learn: Timeline and platform: rollout on Oct 26; liftoff on Nov 2, 2025; LVM3-M5 from SDSC SHAR, Sriharikota; fifth operational flight. Capability upgrade: GSAT-7R ensures continuity as GSAT-7 ages, delivering secure, high-capacity voice/data/video links across the fleet and Maritime Operations Centres. Coverage and operations: resilient multi-band links for blue-water operations in the Indian Ocean Region, enabling stronger command-and-control at sea. Payload specifics: multi-band transponders (UHF, S, C, Ku), indigenous collapsible antennas, 1,200-litre propulsion tank; ~15-year design life. Orbit profile and tests: sub-GTO insertion for mass margins, orbit-raising to geostationary slot; satellite healthy after “perfect injection”; cryogenic upper-stage re-ignition validated. Why it matters nationally: heaviest GTO-class communication satellite launched from Indian soil, enabling more heavy missions and deepening defence-space self-reliance.
