The Indian Space Research Organisation (ISRO) is poised to launch the GSAT-7R (CMS-03) communication satellite today, November 2, 2025. This significant event will take place at the Satish Dhawan Space Centre located in Sriharikota.
Weighing in at 4,410 kg, the GSAT-7R satellite is noted for being the heaviest satellite ever launched from Indian territory into a Geosynchronous Transfer Orbit (GTO). It will be transported by the LVM3-M5 rocket, also referred to as “Bahubali” due to its heavy-lift capabilities.
The launch is scheduled for 5:26 PM IST. The LVM3-M5 rocket stands at 43.5 meters tall and has been fully integrated with the spacecraft, which has already been moved to the second launch pad for pre-launch preparations. This mission represents the fifth operational flight of the LVM3 vehicle, also known as the Geosynchronous Satellite Launch Vehicle (GSLV) Mk III.
The LVM3 is structured with three stages: two solid motor strap-ons (S200), a liquid propellant core stage (L110), and a cryogenic stage (C25). This configuration offers ISRO complete autonomy in launching heavier communication satellites, with a capacity of up to 4,000 kg into GTO.
For those interested in witnessing the launch, it will be live-streamed on ISRO”s official YouTube channel, allowing viewers to follow the liftoff and subsequent mission developments in real time. Additionally, the event will be broadcast live on DD National, the state-run news channel.
The GSAT-7R satellite is designed to enhance the Indian Navy”s communication network and bolster its maritime domain awareness across the Indian Ocean Region. This advanced satellite is anticipated to significantly improve the Navy”s capabilities in space-based communications.
ISRO highlights that the LVM3 rocket can carry payloads of up to 4,000 kg to GTO and up to 8,000 kg to Low Earth Orbit. The solid rocket boosters (S200), developed at the Vikram Sarabhai Space Centre in Thiruvananthapuram, provide essential thrust during liftoff. The liquid stage, powered by two Vikas engines, was crafted and developed at the Liquid Propulsion Systems Centre.
Previously, the LVM3 has been instrumental in significant missions, including the Chandrayaan-3 mission, which successfully achieved a landing near the lunar South Pole in 2023. This upcoming launch further solidifies India”s capabilities in deploying cutting-edge communication satellites independently.
