Cabinet nod to GSLV Ph-4 Continuation Programme

The Union Cabinet has approved the continuation of the ongoing Geosynchronous Satellite Launch Vehicle (GSLV) programme phase-4 consisting of five rocket flights during 2021-2024.

GSLV Ph-4

  • The GSLV phase four will enable the launch of two-tonne class of satellites for geo-imaging, navigation, data relay communication and space sciences.
  • The total fund requirement for phase four has been pegged at Rs 2729.13 crores. The cost includes the cost of five Geosynchronous Satellite Launch Vehicles (GSLVs), essential facility augmentation, programme management, and launch campaign, along with the additional funds required for meeting the scope of the ongoing programme.
  • The GSLV continuation programme is expected to meet the launch requirement of satellites for providing critical satellite navigation services, data relay communication for supporting the Indian human spaceflight programme and the next interplanetary mission to Mars.
  • The continuation programme will meet the demand for the launch of satellites at a frequency up to two launches per year.

The GSLV continuation programme was initially sanctioned in 2003, and two phases have been completed and the third phase is in progress and expected to be completed by the fourth quarter of 2020-21.

Military Communication Satellite GSAT-7A successfully launched by ISRO

Indian Space Research Organisation (ISRO) successfully launched the communication satellite GSAT-7A on 19th December 2018 from the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh. GSAT-7A weighing 2250 kg was launched using Geosynchronous Satellite Launch Vehicle (GSLV-F11).

About GSAT-7A Satellite:

  • ISRO’s GSAT-7A satellite is the heaviest satellite (2250 kgs) with an indigenously developed cryogenic stage that has been launched by GSLV.
  • GSAT-7A is a high-tech communication satellite having new technologies including a Gregorian Antenna.
  • It is the 39th communication satellite of ISRO and will mainly be used for military applications. Indian Air Force’s existing communication capabilities of satellites will be augmented with GSAT-7A
  • GSAT-7A will offer services to the users in Ku-band over the Indian region.

The launch of GSAT-7A was the 13th flight of GSLV-MkII and the seventh flight with an indigenously developed cryogenic engine. GSAT-7A was lifted off by GSLV which is ISRO’s fourth generation launch vehicle with three stages. The first stage consists of four liquid strap-ons and a solid rocket motor. The second stage of GSLV has a high thrust engine using liquid fuel. The third and final stage of the GSLV is the cryogenic upper stage.
