GSAT-7R
Indian military communications satellite
GSAT-7R (also known as CMS-03) is a multi-band communication satellite developed by 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), is meant to transmit voice, video and data among the naval ships, submarines, aircraft and Maritime Operation Centres of the Indian Navy deployed across the Indian Ocean Region, covering up to 2,000 km from India's coastline.
The satellite employs advanced payloads in multiple frequency bands, including UHF, S, C and Ku bands. It is also equipped with indigenous components like a 1,200 litres (260 imp gal; 320 US gal) propulsion tank and collapsible antenna systems. It also has a planned lifespan of 15 years.
The contract for the ₹1,589 crore (US$225.65 million) satellite project was signed on 11 June 2019 between the Indian Navy and the ISRO.
History
During the time of contract signing in 2019, the projected launch date of the satellite was expected between 2020 and 2022.By August 2025, the delivery timeline had slipped by few years to November 2025. By 23 October, the launch date was scheduled on 2 November. The vehicle performance of LMV3-M5 had been enhanced by 10% to accommodate the CMS-03 satellite which is heavier than its payload capacity of 4 tonnes (3.9 long tons; 4.4 short tons) for GTO orbits.
The satellite assembly and integration with launch vehicle has been completed by early October 2025.
Begin with the source’s own compact description: “GSAT-7R” is indian military communications satellite. The dossier treats that line as a proposition to test through GSAT-7R, Indian and military, not as a finished interpretation.
Why this record matters
The phrase “indian military communications satellite” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q85762427. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2019, 2020, 2022 and 2025.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
