ISRO successfully launched communication satellite GSAT-29


Communication satellite GSAT-29 was launched successfully by the second developmental flight of Geosynchronous Satellite Launch Vehicle Mark III (GSLV MKIII-D2) from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.

GSAT-29 :

  • Communication satellite GSTA-29 weighing 3,423 kg is a multiband and multi-beam satellite.
  • The mission life will be 10 years.The satellite’s Ku-band and Ka-band payloads will cater to the communication needs of people residing in remote parts of the country especially those from Jammu & Kashmir and North-Eastern regions.
  • Similarly, the satellite’s Q/V-Band communication payload will help in demonstrating the future high throughput satellite system technologies.


  • GSLV MKIII is ISRO’s fifth generation three stage heavy lift launch vehicle. The launch vehicle is capable of placing satellites weighing 4000 kg in GTO.
  • The first stage constitutes two massive boosters with solid propellants.
  • The core with liquid propellant and the cryogenic engine constitutes the second and third stages respectively. The weight of GSLV Mark III is 641 tons roughly equals the weight of five fully loaded passenger aircrafts. GSLV MarkIII, which took 15 years to make, is the heaviest among India’s operational launch vehicles.
  • Also, with only 43 meters tall, it is also the the shortest launch vehicles. GSLV MKIII will be used to launch Chandrayaan-2 and Gaganyaan missions.
