ISRO inducts THAICOM-3 transponders

Email this story to a friend. The Indian Space Research Organisation has increased the capacity of the INSAT communications satellite system, making it one of the largest domestic satellite communications systems.

ISRO has leased six linear c-band transponders from in-orbit satellite THAICOM-3 that is located at 78.5 degrees east longitude for one year from August 15, 1998, an ISRO statement said.

The number of transponders has shot up to 70 now from a mere 14 during the Indian government's Seventh Five-Year Plan period.

The statement said there has been tremendous growth in satellite derived services in India, especially for television and radio broadcasting and distribution and the 'very small aperture terminal' networks.

The lease of transponders of THAICOM-3 from the Shinawatra Satellite Public Company of Thailand will help in meeting the INSAT transponders' requirement during the transition period between the end of the life of INSAT-1D, the last of the INSAT-1 series of satellites launched in June 1990 and the launch of INSAT 2E, which is expected by December 1998/January 1999.

INSAT 1D, which was procured from the United States, is now in an inclined orbit but is still being used for meteorological services.

The Department of Telecommunications and Doordarshan would use the leased transponder on THAICOM-3.

THAICOM-3 is a three-axis stabilised satellite built by Aerospatiale of France and comprises 39 transponders in c-band and Ku-band frequencies.

The European Arian rocket launched it on April 16, 1997.
