Indian Space Research Organization (ISRO)’s communication satellite CMS-03 (GSAT-7R), weighing more than 4,000 kg, was successfully launched and installed in space on Sunday (November 2, 2025). This CMS-03 satellite is the most advanced communication satellite of the Indian Navy so far, which has been launched from the Satish Dhanav Space Center in Sriharikota, Andhra Pradesh.

ISRO said that this satellite weighing 4,410 kg is the heaviest satellite to be launched from Indian soil in Geosynchronous Transfer Orbit (GTO). This satellite was launched through the LVM3-M5 rocket, which has been named ‘Baahubali’ for its heavy lifting capacity.

ISRO had posted the information

ISRO said in a post shared on social media platform X on Sunday (November 2, 2025), ‘Launch day of LVM3-M5. India’s heavy-lift spacecraft will be launched today on Sunday (November 2) at 5:26 pm on CMS-03. At the same time, an ISRO official had told PTI during the day on Sunday (November 2), ‘The 24-hour countdown started at 5:26 pm on Saturday and is continuing smoothly.’

He said LVM-03 is ISRO’s new heavy lift launch vehicle and will be used to place 4,000 kg spacecraft in GTO in a cost-effective manner.

Kudos Team #ISRO,

India’s #Bahubali scales the skies, with the successful launch of #LVM3M5 Mission!

The satellite has been completely designed in India

This satellite of the Indian Navy has been completely designed in India. Construction has also been done. This satellite will establish fast and secure communication between naval ships, aircraft, submarines and maritime operations centres. Along with this, the Indian Navy will also keep an eye on every action of the enemy in the maritime area.

This three-stage launch vehicle consisting of two solid motor ‘strap-ons’ (S200), a liquid propellant core stage (L110) and a cryogenic stage (C25) provides ISRO complete self-sufficiency in launching heavy communication satellites weighing up to 4,000 kg to GTO. LVM-03 is also called Geosynchronous Satellite Launch Vehicle (GSLV) MK3 by ISRO scientists. ISRO said that LVM3-M5 is the fifth expeditionary flight.
