New Delhi: With the successful launch of CMS-03, its heaviest communication satellite to date, the Indian Space Research Organisation (ISRO) reached yet another milestone on 2 November. This mission strengthens India’s independence in satellite technology and maritime defence.
The satellite, which weighed 4,410 kg, was launched at 5:26 p.m. IST from the Satish Dhawan Space Centre in Sriharikota atop the potent LVM-3 rocket, dubbed the “Bahubali” of Indian rockets. About 16 minutes after liftoff, the spacecraft entered a geosynchronous transfer orbit and broke away from its launcher. India’s ability to deploy heavy communication satellites domestically has advanced significantly as a result of the mission.
The CMS-03 satellite, also referred to as GSAT-7R, is intended to act as the Indian Navy’s communications backbone, providing safe and continuous connectivity throughout the expansive Indian Ocean Region (IOR). It provides high-capacity voice, data, and video links between ships, submarines, aeroplanes, and shore-based stations. It is outfitted with multi-band payloads that operate in the C, extended C, and Ku bands.
The CMS-03, a sophisticated replacement for GSAT-7 “Rukmini,” supports network-centric naval operations and improves maritime domain awareness by providing increased bandwidth, improved encryption, and wider frequency support (including the UHF, S, C, and Ku bands). Its coverage of the Indian subcontinent and surrounding oceanic zones guarantees real-time communication, even in disputed or remote waters.
Additionally, civilian applications like telemedicine, remote sensing and disaster management will be supported by the satellite’s constant geosynchronous coverage. In line with the “Atmanirbhar Bharat” vision, CMS-03 helps India lessen its reliance on international platforms for strategic communication.
In addition to enhancing India’s command, control and communication capabilities in one of the most vital maritime theatres in the world, the mission enhances ISRO’s reputation for heavy-lift launches.
