ISRO To Launch Indian Navy’s Most Advanced Communication Satellite GSAT-7R Today

In a major boost to India’s maritime communication capabilities, the Indian Space Research Organisation (ISRO) is set to launch the Indian Navy’s latest and most advanced communication satellite — GSAT-7R (CMS-03) — from the Satish Dhawan Space Centre, Sriharikota, today (2 November).

In a statement, the Defence Ministry said the indigenously designed and developed satellite will mark a significant step in strengthening the Navy’s space-based communications and maritime domain awareness network.

The launch underlines India’s growing emphasis on Aatmanirbharta (self-reliance) in defence technology.

Weighing approximately 4,400 kg, GSAT-7R is India’s heaviest communication satellite to date.

It incorporates several state-of-the-art indigenous components tailored to meet the operational needs of the Indian Navy, the ministry said.

Equipped with a suite of multi-band transponders, the satellite will provide robust telecommunication coverage across the Indian Ocean Region (IOR), enabling secure voice, data, and video connectivity.

Once operational, GSAT-7R will link ships, submarines, aircraft, and Maritime Operations Centres through a seamless high-bandwidth network.

The advanced satellite is expected to significantly enhance the Navy’s capacity to coordinate real-time operations, improve situational awareness, and support long-range missions across India’s vast maritime boundaries.

Highlighting the strategic importance of the launch, the Defence Ministry stated that GSAT-7R “represents the Indian Navy's determination to protect the nation’s maritime interests leveraging advanced technology through Aatmanirbharta.”

The GSAT-7R follows earlier dedicated naval communication satellites — GSAT-7 (Rukmini) and GSAT-7A — and is expected to further strengthen India’s secure maritime communication infrastructure.
