ISRO launched First Military Communication Satellite – GSAT-7 Rukmini to monitor Chinese submarines

The Indian Navy has been keeping a close tab on Chinese submarines entering the Indian Ocean Region through its very own military satellite GSAT-7, also known as Rukmini. GSAT-7 Rukmini, weighing nearly 2650 kg was the first military communication satellite developed by Indian Space Research Organisation (ISRO) for the Indian Defence forces with the Indian Navy being the primary user. Rukmini is the last of ISRO’s seven fourth generation satellites.

Rukmini was launched early on August 30, 2013 a top an Ariane 5 ECA rocket from Kourou in French Guinea. This gave India a major push in maritime security.

It was successfully placed into a geosynchronous Orbit around 3600 km above Earth, nearly five days prior to its launch after atleast 3-orbit raising manoeuvres from ISRO’s Master Control Facility in Karnataka’s Hassan.

Rukmini is used exclusively by the Indian Navy to secure real-time communications between its numerous warships, aircraft, submarines and land-based communication systems.

The GSAT-7 also has an approximately 2000 nautical mile footprint over the Indian Ocean Region (IOR). It is an advanced communication satellite that will provide a wide range of service spectrum from low bit rate voice to high bit rate data communication.

Scientists say, its payload is designed to provide communication capabilities to users over a wide oceanic region which include the Indian Land Mass.
