India's maritime security will get a fresh impetus as the stage is now set for the launch of an exclusive home-built satellite for the Navy by European space consortium Arianespace from Kourou spaceport in French Guiana on Friday.
GSAT-7 is India's first dedicated spacecraft for defence applications. ‘It has frequency bands that will help marine communications’, an official of Bangalore-headquartered Indian Space Research Organisation, which built the satellite, said here.
‘It has coverage over India landmass as well as surrounding seas. It's important from security and surveillance points of view’, the official said on condition of anonymity.
A senior space scientist in the know said: ‘So far, Navy had limitation from line of sight and ionospheric effects etc. It was thought essential to have an integrated platform for their exclusive use. Earlier, satellite communication in ships was through Inmarsat (a major provider of global mobile satellite communications services). Now, India will have its own set up’.
ISRO shies away from calling it an exclusive satellite for the Navy on record, but privately admits exactly that.
The Rs 185 crore state-of-the-art satellite carries payloads operating in UHF, S, C and Ku bands. GSAT-7 has a lift-off mass of 2625 kg and is based on ISRO's 2500 kg satellite bus with some new technological elements, including the antennae. Its solar arrays generate 2900 W of electrical power.
GSAT-7 is scheduled to be launched into a Geosynchronous Transfer Orbit (GTO) by Ariane-5 VA 215 during the 50-minute launch window starting from 2 am on Friday.
The launch cost for ISRO is around Rs 470 crore, including insurance.
