GSat 6 [ISRO]
The indian Cabinet in December 2004 gave its approval to undertake design, develop & launch GSAT-6 / INSAT-4E, a multi-media mobile satellite system, at a total estimated cost of Rs. 269 crores with a foreign exchange component of Rs. 102 crores. Indian Space Research Organisation (ISRO)) proposes to build a state-of-the-art National Satellite System (GSAT-6) / INSAT-4E) that will offer a Satellite Digital Multimedia Broadcasting (S-DMB) service, via mobile phones and mobile video/audio receivers for vehicles. The satellite capability can also be utilized for strategic and social applications. This satellite will also provide a platform for developing techniques and technologies which will be useful in future satellite based mobile communication applications such as demonstration of large unfurlable antenna in spacecraft, handheld ground terminals and network management techniques. GSAT 6/INSAT-4E will have five C × S transponders each of 9 MHz bandwidth and five S × C transponders each of 2.7 MHz bandwidth which will together cover the entire country. GSAT-6 / INSAT –4E is a part of GSAT/INSAT system planned for initiation in 10th Five Year Plan and the funds have been already provided in the approved 10th Plan. The GSAT-6 / INSAT-4E will be launched in 2010 by the GSLV with a lift-off capability of 2100 kg. The life of the satellite will be 12 years.
INSAT-4 series is planned to have seven satellites, INSAT-4A through INSAT-4G with INSAT-4D as a spare. The transponder capacity of this series has been worked out after evaluating the requirement projected by different uses/user departments. It is planned that, by 2007, INSAT system will have about 250 transponders in various bands catering to a demand of up to 11 Giga Bits Per Second (GBPS) capacity.
