GSAT-10 is an Indian communication satellite launched in September 2012 aboard the Ariane-5ECA rocket. It carries a total of 12 Ku-band, 12 C-band, and 6 lower extended C-band transponders, along with a navigation payload designed to enhance the capabilities of the GPS-aided geo-augmented navigation system (GAGAN). After completing its launch and in-orbit verification, GSAT-10 was positioned at 83.0° East in geosynchronous orbit to deliver communication services across India.
Payload
- Twelve high-power Ku-band transponders powered by 140 W traveling-wave tube amplifiers (TWTA), utilized by Tata Sky.
- Twelve C-band transponders equipped with 32 W TWTA units.
- Six extended C-band transponders, each with a bandwidth of 36 MHz and employing 32 W TWTAs.
- A GAGAN navigation payload functioning on L1 and L5 frequency bands.[1]
Satellite
Commissioned with a projected operational lifespan of 15 years, GSAT-10 became functional by November 2012, enhancing telecommunication, Direct-To-Home broadcasting, and radio navigation capabilities. Weighing 3,400 kg at launch, it was the most massive satellite constructed by the Bengaluru-based Indian Space Research Organisation (ISRO) at that time. Marking ISRO's 101st mission, the satellite was deployed via Arianespace's Ariane-5 ECA heavy-lift rocket approximately 30 minutes after liftoff from the European spaceport in South America at 2:48 AM. Prior to GSAT-10’s deployment, the rocket had successfully placed its European counterpart, ASTRA 2F, into orbit. Equipped with 30 transponders—comprising 12 Ku-band, 12 C-band, and six Extended C-band units—GSAT-10 significantly boosts the transponder capacity of the INSAT/GSAT network. Its GAGAN payload delivers enhanced GPS signal precision with accuracy better than seven metres, supporting civil aviation operations managed by the Airports Authority of India. This satellite represents the second INSAT/GSAT platform to feature the GPS Aided Geo Augmented Navigation (GAGAN) payload following GSAT-8’s launch in May 2011.
Launch
Following GSAT-8’s May 2011 deployment, GSAT-10 became the second satellite in the INSAT/GSAT series equipped with the GAGAN payload. It was successfully launched on 29 September 2012 at 2:48 AM Indian Standard Time (IST) aboard an Ariane-5 rocket from Europe's spaceport located in French Guiana.
Cost
The total expenditure for GSAT-10, including its launch services, amounted to ₹750 crores.
