A rocket carrying two satellites, among  them the GSAT-10, blasts off from Kourou, French Guiana Bangalore: India’s advanced communication satellite GSAT-10 was successfully launched early on Saturday on board Ariane-5 rocket from Europe’s spaceport in French Guiana. and will augment telecommunication, Direct-To-Home and radio navigation services. At 3,400kg at lift-off, GSAT-10 is the heaviest built by Bangalore-headquartered Indian Space Research Organisation. It was ISRO’s 101st space mission. Arianespace’s heavy lifting Ariane-5 ECA rocket launched GSAT-10 about 30 minutes after the blast off from the European launch pad in South America at 2.48am, prior to which it injected European co-passenger ASTRA 2F into orbit. GSAT-10 is fitted with 30 transponders (12 Ku-band, 12 C-band and six Extended C-Band), which will provide vital augmentation to INSAT/GSAT transponder capacity. It also has a navigation payload – GAGAN (GPS aided Geo Augmented Navigation) -- that would provide improved accuracy of GPS signals (of better than seven metres) to be used by Airports Authority of India for civil aviation requirements. This is the second satellite in INSAT/GSAT constellation with GAGAN payload after GSAT-8, launched in May 2011. GSAT-10 was originally scheduled for a September 22 launch, but was deferred after scientists detected a small glitch — one gram of dust — in the upper part of the rocket. GSAT-10 project director TK Anuradha, department of space additional secretary S Srinivasan and ISRO Satellite Centre director SK Shivakumar were among the ISRO officials who were in French Guiana for the launch. Shivakumar said GSAT-10 would give an impetus to the “communication revolution” in India. ISRO chairman K Radhakrishnan was at the space agency’s Master Control Facility at Hassan in Karnataka at the launch, ISRO sources said. “The MCF has already taken command and control of the heavy satellite,” he said minutes after the launch. “By November 2012, we expect to operationalise GSAT-10 and make it available to the user community,” said Radhakrishnan, also secretary, department of space and Space Commission chairman.
