ISRO CMS-03 Mission: India’s Heaviest Communication Satellite Soars into Orbit
November 2, 2025 • Sriharikota, India
The Indian Space Research Organisation (ISRO) marked another proud milestone on November 2, 2025, with the successful launch of the CMS-03 communication satellite aboard the LVM3-M5 rocket, popularly known as the “Bahubali Rocket.” The mission lifted off from the Satish Dhawan Space Centre, Sriharikota at 17:26 IST, showcasing India’s expanding capabilities in space communication technology.
Mission Overview
The CMS-03 satellite, weighing about 4,410 kg, is India’s heaviest communication payload. It was placed successfully into a Geosynchronous Transfer Orbit (GTO) after a smooth 16-minute flight. The LVM3-M5, a 43.5-meter-tall vehicle, uses a combination of solid, liquid, and cryogenic propulsion stages, making it ISRO’s most powerful operational rocket.
Key Technical Highlights
- Launch Vehicle: LVM3-M5 (5th operational mission)
- Payload Mass: 4,410 kg (CMS-03 satellite)
- Orbit Type: Geosynchronous Transfer Orbit (GTO)
- Cryogenic Stage Test: Successful in-orbit re-ignition of C25 stage
- Launch Site: Second Launch Pad, SDSC Sriharikota
Strategic and Scientific Importance
The CMS-03 satellite is designed to enhance maritime and defence communication networks, offering secure voice, data, and video connectivity across India’s land and oceanic regions. It replaces the earlier GSAT-7 “Rukmini” and expands coverage for the Indian Navy, improving communication resilience in the Indian Ocean Region.
This mission reaffirms ISRO’s heavy-lift launch capabilities and aligns with India’s Atmanirbhar Bharat initiative in high-end satellite technology. The precision execution reflects India’s rise among global space powers.
Next Steps and Future Plans
Following orbital insertion, the satellite will perform controlled orbit-raising maneuvers to reach its final geostationary slot. Engineers will deploy antennas and test onboard systems before beginning operations. ISRO plans seven additional missions in this fiscal year, including another LVM3 launch targeted for December 2025.
Broader Impact
The CMS-03 mission strengthens India’s communication infrastructure and creates opportunities for commercial heavy-lift satellite launches. Each success enhances ISRO’s global standing, blending precision, perseverance, and innovation to drive national progress.
Conclusion
The CMS-03 launch aboard LVM3-M5 stands as a testament to India’s engineering excellence and space ambition. From liftoff to orbital success, the mission underscores ISRO’s commitment to innovation, national security, and global collaboration. As India continues to advance, missions like CMS-03 pave the way for stronger communication systems and a self-reliant space future.
