  • DTH satellite GSAT 9 (South Asia Sat) blasts off today

    MUMBAI: The countdown clock is ticking away. Come 5:30 pm IST, the evening of 5 May, and the Indian Space Research Organisation (ISRO) will have added another feather to its cap as  its indigenously developed satellite GSAT-9 lifts off from the second launch pad at the Satish Dhawan Space Center in Sriharikota  for its journey into geosynchronous orbit  as a payload on the Geosynchronous Satellite Launch Vehicle Mk II (GSLV-F09).

    The cost of the launch is estimated at around Rs 450 crore (USD 70 million)

    Labeled South Asia Sat, the 2,230 kg weighing satellite boasts 12 Ku-band transponders that will result in a swelling of capacity for India’s DTH television operators  and facilitate TV signal distribution  for its neighbors Nepal, Bhutan, Maldives, Sri Lanka, Bangladesh and Nepal (members of the South Asian Association for Regional Cooperation – SAARC).  

    The satellite also carries India’s fourth GPS aided GEO Augmented Navigation (GAGAN) payload that delivers correction signals for aircraft navigation systems to increase navigation accuracy to three meters, assisting in air traffic management and landing in tough weather and challenging terrain.

    GSAT 9 will be located at 48 degrees east and has a scheduled mission life of around 12  years.

    Arianespace launches GSAT-15 successfully

    MUMBAI: At 3:04 this morning, Arianespace’s A5 rocket blasted off from its launch pad in Kouru, French Guiana with its payload of two satellites Arabsat 6B (BADR7) and GSAT-15. The former found its slot in space 27 minutes later, while the latter attained its Geosynchronous Transfer Orbit (GTO) 43 minutes after launch.  It was a flawless launch on a perfect evening, said officials from ISRO and Arianespace.

     

    India’s satellite control centre at Hasan in Karnataka is in control of the satellite  at the time of writing and maneuvres over the next three days will see it attaining its geo-stationary orbit at 93.5 degrees East. It will be replacing two ageing satellites Insat3A and Insat 4B.

     

    GSAT-15 has 24 Ku-band transponders to serve the needs of DTH and satellite TV operators over India as well as  VSAT operators who provide DSNG operations to news channels. It  also carries the  GPS-Aided GEO Augmented Navigation (GAGAN) payload operating in L1 and L5 bands,  to enable communications for civil aviation and other location-based services.

     

    Speaking from Kouru ISRO Satellite Centre (ISAC) Director M Annadurai said two other  communication satellites GSAT-17 and GSAT-18 are getting ready for launch by an Ariane vehicle in the next year. “The realisation of both the satellites is in a very advanced stage,” he said.
