Speaking to the media while on the way here for attending the convocation at the Bharathidasan University, Sivan said, GSAT 11, weighing 5.6 tonnes, was the heaviest satellite ever made by India and it would be launched in April or May. It would enable high speed net connectivity to benefit rural India. “Since the launching facility for such a heavy satellite is not available in India, we have sought the support of France,” he said.
