Specifications of GSAT-30:
- GSAT-30, an Indian communication satellite will replace INSAT 4A launched in 2005.
- It has been launched using an Ariane 5 launch vehicle from the Guiana Space Centre.
- 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 (both ranging from 1 to 40 gigahertz).
- It is equipped with 12 C and 12 Ku band transponders.
- The satellite is 3,357-kgs, which has been deployed into geostationary transfer orbit (GTO).
- It is configured on ISRO’s enhanced I-3K Bus structure to provide communication services.
- It has a mission life of 15 years.
- Along with GSAT-30, Arianespace orbited EUTELSAT KONNECT, a telecommunication satellite for the operator Eutelsat.
- Since the launch of India’s APPLE experimental satellite in 1981, Arianespace has orbited 24 satellites, including GSAT-30, for ISRO.
Replacement of INSAT-4A:
- INSAT-4A, first in INSAT-4 satellites series provided services in Ku and C-band frequency bands.
- At the time of launch, it was the heaviest satellite India had produced.
- The Ku transponders covered the Indian mainland and C-Band transponders covered an extended area.
- It was also placed by Ariane launch vehicle (ARIANE5-V169).
- The satellite was placed in the graveyard orbit on 21 October 2019.
- It served for almost 14 years.
Services provided by GSAT-30:
- Provides high-quality television, telecommunications and broadcasting services.
- Provides 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.
- The satellite will be used for bulk data transfer for a host of emerging telecommunication applications.
- The satellite will provide Ku- band coverage to Indian mainland and islands and extended C-band coverage to Gulf countries, a large number of Asian countries and Australia.
