Devas To Introduce Spot Beam Transmission In India

NEW DELHI- Devas Multimedia will introduce spot-beam transmission for the first time in India once the GSat-6 and GSat-6A satellites are launched by the Indian Space Research Organization (ISRO).

A spot beam is a satellite signal with concentrated power that is sent by a high-gain antenna and focused on a limited geographic area.

The $250 million satellite communications company entered into a partnership with Antrix Corp., ISRO’s marketing arm, to lease five transponders each from the GSat-6 and 6A satellites that were to be launched 18 months ago but were delayed following the failure of a cryogenic engine on India’s Geosynchronous Satellite Launch Vehicle in April. Launch is now slated for mid-2011.

GSat-6 is a multimedia mobile satellite system serving mobile phones and mobile video/audio receivers for vehicles. “This satellite will also provide a platform for developing techniques and technologies, which will be useful in future satellite-based mobile communication applications such as demonstration of large unfurlable antenna in spacecraft, hand-held, ground terminals and network management techniques,” ISRO says.

Since the Mumbai terrorist attacks of 2008, real-time communications and tracking have become crucial to Indian security. “Strategic communication is a big issue for homeland security and for rural connectivity,” says Ramachandran Viswanathan, president and CEO.

Devas systems are currently under evaluation by numerous government agencies for applications including homeland security, border security, railways and telecom.

Devas’ backers include Deutsche Telekom, Columbia Capital and Telcom Ventures.
