Why in news?

Recently, the Indian Space Research Organisation (ISRO) has launched telecommunication satellite GSAT-30 into a Geosynchronous Transfer Orbit (GTO) from Kourou launch base, French Guiana by European Ariane-5 VA-251.


  • GSAT-30 satellite will replace INSAT-4A which was launched in 2005.
  • European communication satellite named EUTELSAT KONNECT was also launched with GSAT-30.
  • GSAT-30 derives its heritage from ISRO’s earlier INSAT/GSAT satellite series and will replace INSAT-4A in orbit.
  • GSAT-30 is configured on ISRO’s enhanced I-3K Bus structure to provide communication services from Geostationary orbit.
  • It was launched from the foreign launcher because it is much heavier than the lifting capacity of its geostationary launch vehicle GSLV-MkII (It has the capacity to lift 2500kg).
  • The GSLV-MkIII can lift up to 4,000 kg, but ISRO plans to use the upcoming MkIIIs mainly for its first human space flight Gaganyaan of 2022.


  • It will provide DTH (direct to home) television services, connectivity to VSATs (that support working of banks’) ATMs, stock exchange, television uplinking and teleport services, digital satellite news gathering and e-governance applications.
  • The satellite will also be used for bulk data transfer for a host of emerging telecommunication applications.

Area Coverage :

  • The satellite provides Indian mainland and islands coverage in Ku-band and extended coverage in C-band covering Gulf countries, a large number of Asian countries and Australia.
