Data Communication Satellites
India’s telecommunication satellite GSAT-30 was successfully launched into a Geosynchronous Transfer Orbit (GTO) on January 17, 2020 from Kourou launch base, French Guiana by Ariane-5 VA-251.
GSAT-30 is configured on ISRO’s enhanced I-3K Bus structure to provide communication services from Geostationary orbit in C and Ku bands. The satellite derives its heritage from ISRO’s earlier INSAT/GSAT satellite series.
Weighing 3357 kg, GSAT-30 is to serve as replacement to INSAT-4A spacecraft services with enhanced 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.
The designed in-orbit operational life of GSAT-30 is more than 15 years.
India’s telecommunication satellite, GSAT-31 was successfully launched on February 06, 2019 from Kourou launch base, French Guiana by Ariane-5 VA-247.
GSAT-31 is configured on ISRO’s enhanced I-2K Bus, utilising the maximum bus capabilities of this type. This satellite will augment the Ku-band transponder capacity in Geostationary Orbit.
Weighing about 2536 kg, GSAT-31 will provide continuity to operational services on some of the in-orbit satellites. The satellite derives its heritage from ISRO’s earlier INSAT/GSAT satellite series. The satellite provides Indian mainland and island coverage.
The designed in-orbit operational life of GSAT-31 is about 15 years.
GSAT-7A is the 35th Indian Communication satellite built by ISRO. GSAT-7A Spacecraft is configured on ISRO’s standard I-2000 Kg (I-2K) Bus. The Satellite is built to provide communication capability to the users in Ku-band over the Indian region.
GSAT-29 satellite with a lift-off mass of 3423 kg, is a multi-beam, multiband communication satellite of India, configured around the ISRO’s enhanced I-3K bus. This is the heaviest satellite launched from India.
GSAT-29 carries Ka/Ku-band high throughput communication transponders which will bridge the digital divide of users including those in Jammu & Kashmir and North Eastern regions of India. It also carries Q/V-band payload, configured for technology demonstration at higher frequency bands and Geo-stationary High Resolution Camera. carried onboard GSAT-29 spacecraft. An optical communication payload, for the first time, will be utilized for data transmission.
GSAT-6A, similar to GSAT-6 is a high power S-band communication satellite configured around I-2K bus. The mission life of spacecraft planned is about 10 years. The satellite will also provide a platform for developing technologies such as demonstration of 6 m S-Band Unfurlable Antenna, handheld ground terminals and network management techniques that could be useful in satellite based mobile communication applications
GSAT-6A was launched by GSLV-F08 on Thursday, March 29, 2018 at 16:56 Hrs (IST) from SDSC SHAR, Shriharikota
