Historic Launch by ISRO

The Indian Space Research Organisation (ISRO) has once again made history by successfully launching the CMS-03 satellite for the Indian Navy. This achievement enhances the Navy's communication capabilities and allows for better surveillance of enemy territories. Notably, this satellite is the heaviest ever launched by ISRO, utilizing the powerful LVM35 rocket, often referred to as 'Bahubali'.

The CMS-03 satellite, also known as GS87R, is designed to significantly improve connectivity among naval ships, aircraft, and submarines. It represents the most advanced communication satellite developed for the Indian Navy to date.

Indigenous Development and Launch

Developed using indigenous technology, the satellite was launched from the Satish Dhawan Space Centre located in Sriharikota, Andhra Pradesh. According to ISRO, the CMS-03 is a multi-band communication satellite that will provide services across a vast maritime region, including Indian territories. Defence Minister Rajnath Singh hailed the launch as a significant milestone in the nation's journey towards self-reliance, congratulating ISRO on this achievement via a social media post.

He emphasized that the successful launch of the CMS-03 satellite exemplifies India's commitment to self-sufficiency and cutting-edge innovation, which continues to bring pride to the nation.

Enhanced Communication Capabilities

A spokesperson from the Navy stated that this satellite will ensure robust telecommunications coverage throughout the Indian Ocean region. The satellite's payload includes transponders capable of supporting voice, data, and video links across various communication bands.

The high-capacity bandwidth provided by the CMS-03 makes it particularly special, allowing for rapid data transfer. This capability will establish a secure, fast, and uninterrupted network among ships, submarines, aircraft, and command centers, further strengthening the maritime power of the Indian Navy.
