Sriharikota: The Indian Space Research Organisation (ISRO) achieved another milestone with the successful launch of its LVM3-M5 rocket carrying the CMS-03 satellite from the second launch pad of the Satish Dhawan Space Centre (SDSC-SHAR) in Sriharikota. The launch marks another major step in India’s space and defense communication capabilities.
The CMS-03 satellite, weighing 4,140 kilograms, is being placed in a Geosynchronous Transfer Orbit (GTO). ISRO scientists noted that it is the heaviest satellite ever launched into GTO by the agency. The advanced satellite is designed to enhance communication systems and provide critical data related to marine and atmospheric conditions, thereby strengthening India’s surveillance and operational efficiency over sea routes.

Developed exclusively for the Indian Navy, the satellite—also known as GSAT-7R—will facilitate secure communication between warships, submarines, and ground control stations. It will serve as a replacement for GSAT-7, which has been operational since 2013, further boosting India’s strategic and defense communication network.
