India’s first defence satellite all set for launch tomorrow

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 (between 2 am and 2.50 am on August 30 Indian time). GSAT-7 is India’s first dedicated spacecraft for defence applications.
The original plan was to launch the 2,550-kg satellite using the Indian Space Research Organisation’s (ISRO) own Geosynchronous Satellite Launch Vehicle (GSLV). However, owing to slip-ups in GSLV’s development schedule, the launch would now be carried out by private company.
So far satellite-based communication has been carried out in the Indian Navy in a somewhat piecemeal manner. While ISRO’s GSAT series of satellites earlier allocated only part of its transponders to the armed forces, a dedicated satellite will broaden the scope of the Navy’s communication and data sharing capabilities.
Built around the INSAT-2000 bus, the GSAT-7 would carry four transponders that can transmit in the Ku-band, along with transponders for transmitting in the S-Band [one transponder] and UHF & C-Band [three transponders]. The satellite has been designed with a service life of nine years.
With the Navy’s focus on maintaining its strategic dominance over the Indian Ocean, where its warships spend most of their deployment time, the satellite would be positioned in the 74 degree east longitude geostationary earth orbit.
Though built specifically for the Navy, the GSAT-7’s capability can be exploited by the Army and the IAF too when required. After the GSAT-7 launch, the IAF, too, will get its own dedicated communication satellite, the GSAT-7A.
According to experts, once GSAT-7 becomes operational, it will be possible to link-up every submarine, aircraft and warship to each other along with their shore-based command. Such a datalink will also make it possible to interlink sea-based strategic missile with radars and sensors. This sensor-weapon synergy would make it possible to engage an enemy target without even physically citing it. A launch readiness review was conducted today at the spaceport at Kourou and approval for lift-off was given.
A giant leap
