The Indian Space Research Organization successfully launched its latest communication satellite GSAT-29, which was put in its orbit by India’s heavy-lift rocket Geosynchronous Satellite Launch Vehicle (GSLV-Mk III). The GSLV Mk III is the designated rocket for India’s first human spaceflight proposed for 2022. Today’s launch was a key test to the GSLV Mk III as it carried the GSAT-29 weighing 3,423 kg and placed it into Geo Transfer Orbit (GTO) just over 16 minutes into its flight.
GSLV Mk III is a three-stage heavy-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). Two massive boosters with solid propellant constitute the first stage, the core with liquid propellant form the second stage and the cryogenic engine completes the final stage.
GSAT-29 is a multiband, multi-beam communication satellite, intended to serve as a testbed for several new and critical technologies. Its Ku-band and Ka-band payloads are configured to cater to the communication requirements of users including those from remote areas especially from Jammu & Kashmir and North-Eastern regions of India.
In addition, the Q/V-Band communication payload onboard is intended to demonstrate the future high throughput satellite system technologies. Geo High-Resolution Camera will carry out high-resolution imaging. Optical Communication Payload will demonstrate data transmission at a very high rate through an optical communication link.
The success of GSLV MkIII-D2 marks an important milestone in the Indian space programme towards achieving self-reliance in launching heavier satellites. The success of this flight also signifies the completion of the experimental phase of GSLV Mark III.
