The Indian Space Research Organisation (ISRO) on Sunday successfully launched the Indian Navy’s GSAT-7R (CMS-03) — the country’s heaviest communication satellite — marking a major leap in India’s space and defence capabilities. The launch took place at 5:26 PM from the second launch pad of the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The satellite was precisely placed into its designated orbit by the LVM3-M5 (Baahubali) rocket.
Weighing 4,410 kg, the indigenously developed multi-band communication satellite is designed to provide secure communication services across India and the surrounding oceanic region. With a mission life of at least 15 years, CMS-03 will greatly strengthen the Indian Navy’s space-based communication and maritime domain awareness, featuring advanced, next-generation technologies built to meet strategic needs.
ISRO Chief: “A Shiny Example of Aatmanirbhar Bharat”
Hailing the successful mission, ISRO Chairman V. Narayanan called CMS-03 “another shiny example of Aatmanirbhar Bharat,” lauding the dedication of ISRO scientists who executed the mission flawlessly despite challenging weather conditions.
“The CMS-03 satellite offers wide oceanic coverage, incorporating several new technologies. It will serve for at least 15 years, enhancing our communication capabilities significantly. The entire ISRO team deserves immense appreciation for this complex yet successful mission,” Narayanan said.
He further revealed that ISRO had conducted a key in-flight experiment with the indigenously developed C-25 cryogenic stage, successfully igniting the thrust chamber after the satellite’s separation. This breakthrough, he added, will enhance future mission flexibility, allowing multiple satellites to be deployed in varied orbits.
Narayanan also highlighted that the LVM3-M5 rocket carried its heaviest payload ever — 4,410 kg to an elliptical orbit — surpassing its standard 4,000 kg capacity to Geosynchronous Transfer Orbit (GTO). “All eight LVM3 launches have been successful, making it a 100% reliable launcher. This same vehicle will power our upcoming Gaganyatri-2 mission,” he said.
Strategic Significance
The deployment of CMS-03 marks a crucial advancement in India’s push to modernize naval communication through indigenous technology. Its enhanced coverage across the Indian Ocean Region will enable better real-time coordination, strengthen network-centric operations, and expand India’s strategic reach in space.
ISRO’s latest success not only showcases India’s growing self-reliance in space technology but also reinforces its emergence as a global space leader — embodying the spirit of Aatmanirbhar Bharat.
