Cabinet approves Continuation of Phase 4 of GSLV

Date: 15 April 2019 Tags: Space

Union Cabinet chaired by Prime Minister has approved continuation of ongoing Phase 4 of Geosynchronous Satellite Launch Vehicle (GSLV) programme consisting of five GSLV flights during the period 2021-2024. GSLV Programme - Phase 4 will enable launch of two tonne class of satellites for geo-imaging, navigation, data relay communication and space sciences.

Benefits

It will meet launch requirement of satellites for providing critical satellite navigation services, data relay communication for supporting Indian Human spaceflight programme and next interplanetary mission to Mars. It will also ensure continuity of production in Indian industry.

It will meet demand for launch of satellites at frequency up to two launches per year, with maximal participation by Indian industry. All the operational flights will be completed during the period 2021-24.

Major impact

The operationalization of GSLV has made the country self-reliant in launching capability of two tonne class of satellites for communication and meteorological applications. Continuation of GSLV Phase 4 Programme will sustain and strengthen capability and self-reliance in launching of similar satellites for national requirements including next generation navigation satellites, data relay communication satellites and interplanetary missions.

Background

GSLV Continuation Programme was sanctioned in 2003, and two phases already have been completed and third phase is in progress and expected to be completed by Q4 of 2020-21.  It has enabled ISRO independent access to space for launching two tonne class of satellites to Geosynchronous Transfer Orbit (GTO). It has helped in mastering of highly complex cryogenic propulsion technology, which is essential technological capability to launch communication satellites to GTO. It also has paved way for development of high thrust Cryogenic engine and stage for next generation launch vehicle i.e. GSLV Mk-lll.  GSLV so far has successfully launched 10 national satellites. With its indigenous Cryogenic Upper Stage, GSLV has established itself as reliable launch vehicle for communication, navigation and meteorological satellites and also to undertake future interplanetary missions.
