Indian Navy Upgrades Satellite Communication with BSNL and Viasat
The Indian Navy is getting a big upgrade to its satellite communication system.
Two companies, BSNL from India and Viasat from the USA, are helping with this upgrade.
They will use special satellites and ground stations to make sure the Navy can communicate better and more securely.
This means that ships, submarines, and aircraft can talk to each other and to their bases without any problems.
The Navy already has a big satellite called CMS-03, which was launched by ISRO in November 2025.
This satellite helps the Navy communicate in real-time, which is very important for their missions.
The upgrade will make everything even better and more reliable.
Indian Navy is upgrading its satellite communication capabilities with support from BSNL and Viasat.
The program will enable a multi-band, multi-constellation satellite communication strategy.
Viasat's high-capacity Ka-band satellite systems will be used alongside existing L-band infrastructure.
The upgrade aims to provide expanded coverage, higher throughput, and improved reliability for mission-critical operations.
ISRO launched the CMS-03 (GSAT-7R) satellite in November 2025 to enhance secure and real-time connectivity for the Indian Navy.

Quotes
Sanjeev Sanyal
Member of the Prime Minister's Economic Advisory Council and a core crew member of the INSV Kaundinya
“Throughout the voyage, having reliable satellite connectivity has been invaluable. It allowed us to stay connected with shore-based teams, supporting communication, live feeds, and above all, morale during long and sometimes challenging periods at sea.”
