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.
