Topics Covered: Awareness in space.


What to study?

For Prelims and Mains: GSAT 30- components and applications, various bands.

Context: The first mission of the Indian Space Research Organisation (ISRO) in 2020, India’s latest telecommunication satellite GSAT-30 was successfully launched recently.

The launch took place from the Spaceport in French Guiana.

The launch vehicle is named Ariane 5 VA-251.

Key facts:

  • 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.

GSAT-30 uses two satellite frequencies:

It gives the Indian mainland and islands coverage in the Ku band, and extended coverage in a wider area stretching from Australia to Europe in the lower-frequency C-band.

The Ku and C bands are part of a spectrum of frequencies, ranging from 1 to 40 gigahertz, that are used in satellite communications.


With a mission life of over 15 years, GSAT-30 will provide DTH [direct-to-home] television Services, connectivity to VSATs [Very Small Aperture Terminals] for ATM, stock exchange, television uplinking and teleport services, Digital Satellite News Gathering (DSNG) and e-governance applications.

What is Arianespace?
It is the world’s first commercial launch service provider and since the launch of India’s APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has orbited 24 satellites, including Gsat-30, for the Indian space agency.
