The Indian Space Research Organisation (ISRO) successfully launched its heaviest communication satellite to date, CMS-03, on Sunday, November 2. The 4,410 kg satellite was carried into a geosynchronous transfer orbit by the powerful LVM-3 rocket, also called the ‘Bahubali’ of Indian rockets, from Sriharikota at 5:26 pm IST. Just over 16 minutes after liftoff, the satellite separated from the launch vehicle, marking a major milestone in India’s journey toward self-reliance in heavy satellite launches and maritime communication.
CMS-03, also known as GSAT-7R, is specifically developed to enhance the Indian Navy’s communication network across the Indian Ocean region. Equipped with advanced multi-band payloads such as C, extended C, and Ku bands, the satellite will provide secure and high-capacity communication channels. These will support voice, data, and video links between naval ships, submarines, aircraft, and command centers on land.
Replacing the ageing GSAT-7 “Rukmini” satellite, CMS-03 brings significantly improved bandwidth and wider coverage. It ensures seamless, real-time connectivity even in remote or strategically sensitive maritime zones, reinforcing India’s oceanic surveillance and defense capabilities. This launch represents a major step forward in strengthening India’s space-based communication infrastructure for national security.
