Two Defence Satellites to be carried by ISRO’s New Rocket


Two small defence satellites to fly by Indian Space Research Organisation in July or August this year on its new rocket, which is now SSLV.

“We are planning to fly two defence satellites, each weighing about 120 kg in our new rocket SSLV this July or August. The rocket design recently underwent a detailed integrated technical review,” said K Sivan, ISRO Chairman.

He said, the total weight of the payload will be about 500kg, and that will be carried by the SSLV on its first flight. Whereas, the weight of the two satellites will be about 120 kg each. There will be adaptors and others that would weigh about 300kg.

The total weight of the rocket will be 110 tonne, said Sivan.

Commenting on the need for a second commercial arm, the first one being the Antrix Corporation, Sivan said, “We want to give a big push for production of SSLV. We expect the demand for SSLV to be about two/three rockets per month. We also want to increase the production of Polar Satellite Launch Vehicle (PSLV).

He also mentioned that the increase in production is sought to be achieved partnering with the private sector and said Antrix Corporation is mainly into transponder leasing and other activities.

The Union Cabinet chaired by Prime Minister Narendra Modi gave its approval for setting up of a new company under the Department of Space (DoS), to commercially exploit the research and development work carried out by ISRO and its constituent units.

The following areas/avenues provide opportunities for commercial exploitation of ISRO programmes:

Small satellite technology transfer to industry, wherein the new company shall take licence from DoS/ISRO and sub-license to industries; manufacture of small satellite launch vehicle (SSLV) in collaboration with the private sector.

Besides, productionisation of PSLV through industry; productionisation and marketing of space-based products and services, including launch and applications; transfer of technology developed by ISRO Centres and constituent units of DoS.

Talking about the technologies that the ISRO can transfer, Sivan said, “We have developed technologies in materials, chemicals and others. These can be transferred so that people can benefit.”
