The GSLV project has successfully launched GSLV-D5 flight with indigenous Cryogenic engine and stage on 5th January 2014 from Satish Dhawan Space Centre, Sriharikota and is currently preparing for the next flight GSLV namely, GSLV-D6.
The GSLV-F02, GSLV-D3 and GSLV-F06 flights could not accomplish the mission objectives. Subsequently, failure analysis committees were formed to (a) carry out in-depth analysis of the flight performance and identify causes for the failure, and (b) recommend corrective measures and future course of action on the GSLV Vehicle. The failure analysis committees have submitted their recommendations.
Based on the suggestions made by the failure analysis committees, ISRO has implemented the modifications and improvements in GSLV, which include independent inspection and quality checks for all critical components and sub-assemblies, change of bearing housing material, revision of tolerances and seal clearances of Fuel Booster Turbo Pump of Cryogenic Engine, redesign of the Cryogenic Stage Lower Shroud, revision of connector mounting scheme and wire tunnel configuration.
SAARC Satellite

India has successfully launched five foreign satellites onboard PSLV-C23 on June 30th, 2014 from Satish Dhawan Space Centre, Sriharikota. These foreign satellites are – (i) SPOT-7 (France), (ii) AISAT (Germany), (iii) NLS 7.1/CAN-X4 (Canada), (iv) NLS 7.2/CAN-X5 (Canada) and (v) VELOX-1 (Singapore).
As on date, Indian Space Research Organisation (ISRO) has launched 40 satellites from 19 foreign countries, on commercial basis, under contract between respective foreign customer and Antrix Corporation Limited, the commercial arm of ISRO. The amount generated through the launch of these satellites is € 50.47 million and US $ 17.17 million.
The future projects envisages development of advanced launch vehicle systems, thematic earth observational satellites with improved resolution, high-power, high-throughput communication satellite, microwave multi-spectral remote sensing satellites, weather and climate studies, constellation of satellites for regional navigation, development of critical technologies for human spaceflight and satellites for space science and planetary exploration purposes.
The Prime Minister of India in his address at Satish Dhawan Space Centre, Sriharikota on 30th June 2014 has asked the Indian Space community to develop a SAARC satellite that provides a full range of applications and services to all our neighbours. ISRO, through the Government of India, in consultation with the SAARC countries, needs to formulate a proposal for SAARC Satellite development programme to address the space applications and services needs of the SAARC countries.
Pricing of Satellite Transponders
|
Based on the review and approval of INSAT Co-ordination Committee (ICC) and Space Commission, a revised policy guideline for allocation and pricing of transponders has been evolved and is being processed for Government approval. It envisages a rational classification structure for users such as Strategic, Government including Societal, not-for-profit PSUs and Commercial to form a basis for allocation and pricing of transponders.
At present, there are 12 INSAT/GSAT satellites in orbit, out of which 10 are communication satellites and 2 are meteorological satellites. In INSAT/GSAT satellite system there are 41 Government users and 59 non-Government users are utilizing the capacity in C band, Extended C Band and Ku band to the extent of 152 transponders (36 MHz equivalent each).
At present, a uniform pricing policy is implemented for all categories of users. However, a multi-pricing policy for transponders is under the consideration of the Government as INSAT systems transponders are utilized for non-profit purposes viz. Governmental, societal, strategic as well as for commercial purposes. |
