GSAT-7R (also known as CMS-03) is a planned multi-band communication satellite developed by the Indian Space Research Organisation (ISRO) for the Indian Navy. The satellite is meant to replace the existing and operational GSAT-7.

Satellite

The satellite, weighing 4,410 kilograms (9,720 lb),[1] will utilise multiple frequency bands, including UHF, S, C and Ku bands, to transmit voice, video and data among the naval ships, submarines and aircraft of the Indian Navy deployed across the Indian Ocean Region, covering up to 2,000 km from India's coastline.[2]

The contract for the ₹1,589 crore (Template:INRConvert/HistoricalRate/Formatted) satellite project was signed in 11 June 2019 between the Indian Navy and the ISRO.[3][4]

Launch

During the time of contract signing in 2019, the projected launch date of the satellite was expected between 2020[3] and 2022.[4]

As of August 2025, the delivery timeline slipped by a year and is now expected to be launched in late 2025 onboard ISRO's Geosynchronous Satellite Launch Vehicle.[5][6]

As of 23 October, the launch is scheduled on 2 November onboard the LVM3-M5 from Satish Dhawan Space Centre, Sriharikota.[7][2] The satellite assembly and integration with launch vehicle has been completed. The launch vehicle was moved to the launchpad on 26 October and pre-launch procedures were initiated thereafter. It is the heaviest satellite to be launched to the Geostationary Transfer Orbit orbit from India. Additionally, this will be the first launch of LVM3, only after its July 2023 launch of Chandrayaan-3.[8][9]

The 24-hour countdown began on 1 November as the launch time is scheduled at 5:26 pm IST.[1]
