In­dia’s satel­lite-based net­work­ing ca­pa­bil­i­ties

Ruk­mini will pro­vide net­work­ing ca­pa­bil­i­ties with var­i­ous In­dian Navy’s as­sets. Dur­ing Theatre-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.

I] ndia launched its first ded­i­cated de­fence satel­lite, GSAT-7, for the In­dian Navy on Au­gust 30, 2013. GSAT-7 was suc­cess­fully launched by the Ariane-5 launch ve­hi­cle of Ari­anes­pace from Kourou, French Guiana. Ariane-5 pre­cisely placed GSAT-7 into the in­tended geosyn­chronous trans­fer or­bit (GTO).

GSAT-7 is an ad­vanced com­mu­ni­ca­tion satel­lite built by In­dian Space Re­search Or­gan­i­sa­tion (ISRO) to pro­vide wide range of ser­vice spec­trum from low bit rate voice to high bit rate data com­mu­ni­ca­tion. GSAT-7 com­mu­ni­ca­tion pay­load is de­signed to pro­vide com­mu­ni­ca­tion ca­pa­bil­i­ties to users over a wide oceanic re­gion in­clud­ing the In­dian land mass. The GSAT-7 pay­load de­sign in­cludes multi-band com­mu­ni­ca­tion. It was thought essen­tial to have an in­te­grated plat­form for the In­dian Navy’s exclusive use. Ear­lier, satel­lite com­mu­ni­ca­tion in ships was through In­marsat, a ma­jor provider of global mo­bile satel­lite com­mu­ni­ca­tions ser­vices.

In­dian Navy’s first ded­i­cated satel­lite, Ruk­mini, went into oper- ational mode soon af­ter Oc­to­ber 13, 2013 and GSAT-7 reached its GTO po­si­tion at 70 de­gree east lon­gi­tude. GSAT-7 is not de­signed for aux­il­iary func­tions like ‘Tar­get­ing Guid­ance,’ which are the es­sen­tially the fea­tures for a ‘sur­veil­lance satel­lite’.

Post-Mum­bai 26/11 ter­ror­ist at­tack, a slew of mea­sures such as coastal radar chain and AIS net­work to im­prove In­dia’s mar­itime do­main aware­ness (MDA) off and along the coast were ini­ti­ated. Ef­forts are on to set up the NC3I net­work and to es­tab­lish a Na­tional MDA sys­tem to seam­lessly in­te­grate in­for­ma­tion from mul­ti­ple sources and mar­itime agen­cies and geospa­tial ap­pli­ca­tions are the core of most of these projects.

Ruk­mini will pro­vide net­work­ing ca­pa­bil­i­ties with var­i­ous In­dian Navy’s as­sets.

The in­ten­tion of In­dian Navy is to use this geo­sta­tion­ary naval com­mu­ni­ca­tion and sur­veil­lance satel­lite to cover ac­tiv­i­ties up to Malacca Strait in the east and the Strait of Hor­muz to the west.
