GSAT-7 or INSAT-4F is a multi-band military communications satellite developed by the
Satellite
GSAT-7, the multi-band communication satellite named Rukmini
The multiple-band spacecraft will be used exclusively by the Navy to shore up secure, real-time communications among its warships, submarines, aircraft and land systems. GSAT-7/ INSAT-4F is said to significantly improve the country's naval operations around the world.
GSAT 7 satellite carrying payloads operating in UHF, S, C and Ku bands, had a lift-off mass of 2,650 kilograms (5,840 lb) and is based on ISRO's 2,000 kilograms (4,400 lb) class satellite bus I-2K with some new technological elements, including the antennae.
ISRO launched a second satellite, GSAT-7A for Indian Air Force on 19 December 2018 on its Geosynchronous Satellite Launch Vehicle (GSLV-F11).[11][12]
Launch
The satellite was launched early on 30 August 2013 atop an
India's first dedicated military satellite was put into a geosynchronous orbit, about 36,000 kilometres (22,000 mi) above Earth, five days after it was launched after three orbit-raising manoeuvres from ISRO's
Capability
Rukmini will provide networking capabilities to various Indian Naval assets. During Theater-level Readiness and Operational Exercise (Tropex) in the Bay of Bengal in 2014, Rukmini was able to network about 60 ships and 75 aircraft seamlessly. Rukmini has a nearly 2,000 nautical mile 'footprint' over the Indian Ocean Region.[17]
Replacement
The Indian Navy placed an order for GSAT-7R on June 11, 2019. GSAT-7R is expected to eventually replace GSAT-7.[18]
