GSAT-7, the multi-band communication satellite named Rukmini[3] satellite carries the payloads in UHF, C-band and Ku-band. It is the first satellite by ISRO that will provide services to the Indian defence forces[4] with the main user being the Indian Navy.[5]The 2,650-kg GSAT-7 is the last of ISRO’s seven fourth-generation satellites. Its foreign launch cost has been put at Rs. 480 crore, with the satellite costing Rs. 185 crore.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 maritime security and intelligence gathering in a wide swathe on the eastern and western flanks of the Indian Ocean region. Around 2014-15, ISRO is expected to launch the second naval satellite, GSAT-7A.[[1]]The state-of-the-art satellite carrying payloads operating in UHF, S, C and Ku bands, had a lift-off mass of 2625 kg and is based on ISRO's 2500 kg satellite bus with some new technological elements, including the antennae.After a flight of almost 34 minutes, the satellite was injected into a geosynchronous transfer orbit (GTO) of 249 km perigee (nearest point to earth), 35,929 km apogee (farthest point to earth) and an inclination of 3.5 degree with respect to the equator.
