ISRO to replace ageing satellites

Chennai, India: The Indian Space Research Organisation (ISRO) plans to replace two of its ageing satellites with new ones by December. The agency is planning to send in space two rockets for the purpose.

One of them is a remote sensing satellite – Resourcesat-2. It will be launched by the polar satellite launch vehicle (PSLV). Piggy-backing on it will be two small satellites made in Singapore and Russia. “The Resourcesat-2 will be the replacement for Resourcesat-1 launched in 2003. For sometime both will work together,” said, S. Satish, ISRO’s director (publications and public relations).

Another satellite will be a communication satellite GSAT 5 – intended to replace the ageing INSAT 2E. It will be launched by the geosynchronous satellite launch vehicle (GSLV) – sometime during the second week of December.

“The INSAT 2E was launched in 1999 and is nearing the end of its life. The GSAT 5 with 36 transponders will be its replacement. Further, the new satellite is also expected to fill the void created by the partial failure of INSAT 4B,” Satish said.

Earlier this year, ISRO lost 50 per cent of the INSAT-4B’s transponder capacity (12 transponders) owing to a power snag.
