GSAT-10 is an Indian communication satellite which was launched by Ariane-5ECA carrier rocket in September 2012. It has 12 KU Band, 12 C Band and 6 lower extended c band transponders, and included a navigation payload to augment GAGAN capacity.[2] Following its launch and on-orbit testing, it was placed in Geosynchronous orbit at 83.0° East, from where it will provide communication services in India.

Payload

  • 12 high power KU-band transponders employing 140 W TWTA. It is being used by Tata Sky
  • 12 C Band Transponders employing 32 W TWTA.
  • 6 extended C-Band Transponders each having a bandwidth of 36 MHz employing 32 W TWTA.
  • GAGAN navigation payload operating in L1 and L5 bands.[3]

Satellite

GSAT-10, with a design life of 15 years was operational by November 2012 and will augment telecommunication, Direct-To-Home and radio navigation services. At 3,400 kg at lift-off, at the time, it was the heaviest satellite built by the Bengaluru-headquartered Indian Space Research Organisation (ISRO). It was ISRO's 101st space mission. Arianespace's heavy lifting Ariane-5 ECA rocket launched the satellite 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 carries 30 transponders (12 Ku-band, 12 C-band and six Extended C-Band), which will provide vital augmentation to INSAT/GSAT transponder capacity. The GAGAN payload will provide improved accuracy of GPS signals (of better than seven metres[4]) which will 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, which was launched in May 2011.

Launch

GSAT-10 is the second satellite in INSAT/GSAT constellation with GAGAN payload after GSAT-8, launched in May 2011. The satellite was successfully launched on 29 September 2012 at 2:48 am (IST) on board Ariane-5 rocket from Europe's spaceport in French Guiana. [5]

Cost

The satellite and launch fee cost the agency ₹750 crores. [6]
