ISRO GSAT-29 Communications Satellite by ISRO launch on Wednesday

GSAT-29 Communications Satellite by ISRO launch on Wednesday: GSAT-29 is a high speed technology communication satellite advanced by the Indian Space Research Organisation (ISRO). The main objective of the project is to provide high-speed communication to Village Resource Centres (VRC) in rural areas. Under Digital India programme, the two operating payloads Ku and Ka will deliver communication facilities to Jammu and Kashmir and Northeast India.

ISRO’s communication satellite GSAT-29 to provide high-speed connectivity in remote areas of India; launch today


  • GSLV-Mk III will put GSAT-29 into Geo Transfer Orbit on Wednesday
  • It will be the second developmental flight of GSLV-Mk III rocket
  • The GSAT-29 satellite has a design life of 10 years

The satellite is scheduled to be launched tomorrow on 14 November 2018 through the second progressive flight of GSLV Mk III named GSLV Mk III D2. The countdown for the take-off of GSLV Mark III rocket started this afternoon on 13th November 2018 at 2:50 PM. GSLV Mark III rocket is carrying the new communication satellite GSAT-29.

The launch of satellite GSAT-29 is scheduled on 14 November, 5:08 PM tomorrow at Sriharikota from Satish Dhawan Space Centre (SDSC) or Sriharikota Range (SHAR) which is a rocket launch centre activated by Indian Space Research Organisation (ISRO). Its headquarters is located in Sriharikota in Andhra Pradesh. Former name, Sriharikota Range was retitled in 2002 after ISRO’s former chairman Satish Dhawan.

Separately from its core communication payload in Ka/Ku bands, GSAT-29 also hosts few of the latest experimental payloads to develop their technology for the further use in future spacecraft’s experiments. Such as

  • Optical Communication Technology (OCT) payload which is an experimental payload for optical communication
  • Q bandand V bandpayload which is an experimental microwave communication payloads
  • GEO High Resolution Camera (GHRC) which is used for high purpose imaging from geosynchronous orbit.

This would be the second test flight of weightiest rocket ever for the Indian Space Research Organization ISRO’s with the launch mass of 3,423 kg (7,546 lb). This kind of launch can insert four-tonne class satellites like communication payloads into a geostationary transmission range.

The satellite GSAT-29 which is going to be launched by the rocket GSLV Mark III carts high input communication transponders in the Ka and Ku bands. It can enlarge high-speed data communication facilities in India’s wide-ranging and remote areas.

ISRO said that in addition of numerous new technologies like Q/V-band payload, data transmission through optical communication link will be established and demonstrated. This will definitely benefit in understanding and releasing future forward-looking satellites.

Overall, tomorrow’s satellite launch mission would be the ISRO’s fifth launch this year and The rocket will carry GSAT-29 weighing over 3.4 tonnes and suspend it into Geo Transfer Orbit (GTO) in just 16 minutes of its flight. Then after which the satellite will be elevated to the final Geo Stationary Orbit (GSO) at the height of 36,000 km from the earth. It weighs 3423 kg during its launch and has a functioning life of over ten years.
