India will launch its home-made heaviest communication satellite GSAT-10, weighed 3,400 kg, from the Kourou launch base in French Guyana on September 29, local media reported.

The satellite has been produced by the state-owned Indian Space Research Organisation (ISRO), with only one of the cryogenic engines sourced from Russia, The Times of India newspaper reported.

The GSAT-10 will be launched at 2.48 am (local time) on September 29, an ISRO spokesperson was quoted as saying.

It will travel to space as a co-passenger of ASTRA-2F made by SES, a global satellite services company. About 31 minutes after lift-off, GSAT-10 would be injected in a geosynchronous transfer orbit with a perigee of 250 km and an apogee of about 36,000 km, the newspaper said.

"The satellite is expected to be operational by November 2012. GSAT-10 satellite will be positioned at 83 degrees east orbital location along with INSAT-4A and GSAT-12. The nominal operational life of GSAT-10 is expected to be 15 years," an ISRO release said.
