The Indian Space Research Organisation (ISRO) launched its heaviest communication satellite on Sunday. The satellite, CMS-03, is reportedly the heaviest ever launched from Indian soil into a Geosynchronous Transfer Orbit (GTO), marking a crucial leap for India’s independent satellite capabilities and maritime security.
The 4,410 kg CMS-03 satellite rode into a geosynchronous transfer orbit aboard the robust LVM-3 rocket, also known as ‘Bahubali of Indian rockets, from Sriharikota at 5:26 pm IST.
“Liftoff! #LVM3M5 launches #CMS03 from SDSC SHAR, carrying India’s heaviest communication satellite to GTO”, wrote ISRO on X,
The spacecraft was launched aboard the LVM3-M5 rocket, also dubbed ‘Bahubali’ for its heavy-lift capabilities. The LVM3 is a three-stage launch vehicle with two solid motor strap-ons (S200), a liquid propellant core stage (L110) and a cryogenic stage (C25).
CMS-03, also referred to as GSAT-7R, is tailor-made to serve as the backbone of the Indian Navy’s communication network across the Indian Ocean.
The satellite is loaded with multi-band payloads, including C, extended C, and Ku bands, that enable secure, high-capacity voice, data, and video transmissions between warships, submarines, aircraft, and shore-based command centers.
Unlike its ageing predecessor GSAT-7 “Rukmini,” CMS-03 offers significantly expanded coverage and bandwidth, ensuring real-time connectivity even in remote or contested ocean zones.
