Revised cost estimates of Geo-synchronous Satellite Launch
Vehicle project for completing the scope of development
programme and experimental flight

The Union Cabinet today gave its approval for revised cost estimates of Rs.2962.78 crore (against the original provision of Rs. 2498.00 crore) for completing the scope of the development programme of Geo-synchronous Satellite Launch Vehicle (GSLV Mk-lll) and to carry out anexperimental flight called LVM3-X.

The additional fund requirement is Rs. 464.78 crore to complete the scope of the project including one experimental flight called LVM3-X and two developmental flights called GSLV Mk-lll D1 and GSLV Mk-lll D2.

Development of the GSLV Mk-lll launch vehicle is expected to augment the capacity of the Indian space programme to launch 4T class satellites to Geo¬synchronous Transfer Orbit (GTO)and thereby significantly reduce the demand-supply gap of transponders in the country.

The indigenous development of the GSLV Mk-lll will facilitate launching of four ton class of communication satellites to Geo-synchronous Transfer Orbit, benefiting all sections of the society, including remote and far-flung areas of the country.

Background

The Geo-synchronous Satellite Launch Vehicle Mark III (GSLV Mk-lll) project was approved in 2002 with an outlay of Rs. 2498 crore. The GSLV Mk-lll Launch Vehicle Programme involves a major leap in technological complexity as compared to the ongoing Polar Satellite Launch Vehicle (PSLV) and GSLV programmes. The original financial sanction needs to be revised, considering the cost escalation in the project elements, modifications in design, new elements etc. required to complete the scope of the project including two development flights. The scope of the project is also required to be augmented to include an experimental flight (Launch Vehicle Mark-Ill - Experimental: LVM3-X) to validate the critical atmospheric regime of the flight.

The Experimental flight of GSLV Mk-lll (LVM3-X) with flight versions of Solid Stages (S200), Liquid Stage (L110) and a passive cryogenic stage (C25) is planned in 2013-14, to validate some of the new systems and flight sequences, hitherto not demonstrated in PSLV/GSLV flights.

The first development flight (GSLV Mk-lll D1) with an operational cryogenic stage is planned in 2016-17. The second development flight (GSLV Mk-lll D2) is planned after one year of GSLV Mk-lll D1 flight in 2017-18.
