Indian Navy Moves to Multi-Band SATCOM as BSNL, Viasat Begin Network Upgrade

NEW DELHI: The Indian Navy is set to strengthen its satellite communication capabilities as Bharat Sanchar Nigam Limited (BSNL) and global satellite services provider Viasat begin the next phase of a network modernisation programme later this month, officials said on Wednesday.

The upgrade will introduce a multi-band satellite communication architecture aimed at improving connectivity, resilience and security for mission-critical naval operations. The programme will deploy Viasat’s high-capacity Ka-band satellite systems alongside the Navy’s existing L-band infrastructure, expanding coverage and increasing data throughput across ships and maritime platforms.

BSNL said the initiative follows a formal agreement with the Indian defence forces and is designed to support the Navy’s transition to a multi-constellation SATCOM framework. The system will operate through BSNL’s Gateway Earth Station, integrated with Viasat’s global satellite network.

The modernisation is expected to enhance operational flexibility for the Navy while ensuring more reliable communication links during extended deployments and complex maritime missions. Viasat’s international government services team will provide technical support during installation and rollout.

BSNL Chairman and Managing Director Robert Ravi said the project reflects the company’s focus on strengthening India’s strategic communications infrastructure through secure and resilient technologies.

Viasat has previously supported several government-led communication initiatives in India, including disaster response networks, tsunami early warning systems and vessel tracking services. The company also provides aeronautical connectivity for government and private aircraft.

Installation activities are scheduled to begin later this month, marking a key milestone in the ongoing effort to modernise India’s defence and maritime communication systems.
