India’s communication satellite GSAT-31 launched from French Guiana


What to study?

For Prelims and Mains: GSAT- 31- features, objectives and significance.


Context: Indian Space Research Organisation’s latest communication satellite, GSAT-31 was successfully launched by Arianespace aboard its launch vehicle Ariane 5 from the spaceport in French Guiana recently.


Ariane 5 carried two communication satellites:

  1. Saudi Geostationary Satellite 1/Hellas Sat 4 and Hellas Sat.
  2. ISRO’s GSAT-31.


About GSAT- 31:

  • A telecommunications satellite designed and manufactured by the Indian Space Research Organisation (ISRO).
  • India’s 40th communication satellite and derives its heritage from ISROs earlier INSAT/GSAT satellite series.
  • It will be placed in Geostationary Orbit (36,000 km above the equator) using its onboard propulsion system.
  • It has a unique configuration of providing flexible frequency segments and flexible coverage. Hence, it will provide communication services to Indian mainland and islands.
  • It will also provide DTH Television Services, connectivity to VSATs for ATM, Stock-exchange, Digital Satellite News Gathering (DSNG) and e-governance applications. The satellite will also be used for bulk data transfer for a host of emerging telecommunication applications.


Key Objectives:

  1. Augment the Ku-band transponder capacity in Geostationary Orbit for at least 15 years.
  2. Provide continuity to operational services on some of the in-orbit satellites.
  3. Help bridge the digital divide in the Indian subcontinent as part of an ambitious Indian space program, whose objectives are to develop India while pursuing scientific research and planetary exploration.
