  • 2014’s first space mission to be India’s GSAT-14

    2014’s first space mission to be India’s GSAT-14

    MUMBAI: The first time it was about to launch in August 2013, a technical snag forced an abortion. But now, India’s Indian Space Research Organisation’s (ISRO’s)  twenty third communication satellite GSAT-14 by the is all set to be launched into space on 5 January 2014 on the Geosynchronous Satellite Launch Vehicle (GSLV)-D5.  The launcher will propel the bird into a Geosynchronous Transfer Orbit (GTS) after which it will use its own propulsion system to reach its geostationary orbital home at 74 degrees east longitude.

     

    The mission is important for ISRO which has been seeking to get a piece of the satellite launch action globally. But it has found things difficult since four out of the seven launches of GSLV have been failures and three previous attempts to use indigenous cryogenic engine have also ended up in a mess.

     

    The previous attempt to blast off GLSV into space in August 2013 was aborted following a fuel leak which developed in its engine hours before launch. ISRO worked on it and gave it a better metal covering, following which it has decided to give it another shot.

     

    A three stage rocket – the first stage runs on solid fuel, the second on liquid fuel and third on a cryogenic engine – the GSLV- D5 will be carrying the 1982 kgs (lift off mass) GSAT-14, which will be replacing GSAT-3 that was decommissioned in 2010. The new satellite’s structure is based on ISRO’s two ton weighing (I-2K satellite bus). The satellite has six Ku band (51.5 dBW EOC-EIRP) transponders, six C band (36 dBW EOC-EIRP) transponders and two Ka band beacons and will be co-located with INSAT-3C, INSAT-4CR and KALPANA-1.

     

    Most of the C- and Ku-band capacity on GSAT-14 will be utilized for long distance education and telemedicine, while the Ka band transponders will help in studying rain and atmospheric effects. This ninth operational geostationary satellite is expected to have a mission life of 12 years and will be able to provide enhanced broadcasting as compared to GSAT-3 for the whole of India.

     

    According to the ISRO website, the mission has three main objectives- to augment the in-orbit capacity of extended C and Ku-band transponders and to provide a platform for new experiments such as fiber optic gyro, active pixel sun sensor, Ka band beacon propagation studies and thermal control coating experiments.

     

    The 29 hour countdown to the launch began at 11:18 am on 3 January with the launch time set as 4:18 pm on 4 January from its launch pad at Satish Dhawan Space Centre (SDSC SHAR) at Sriharikota in Andhra Pradesh. GSLV-D5 is expected to have a 17 minute, eight second flight duration. If successful, this will be 2014’s first space launch as SpaceX’s launch of Thaicom-6 has been postponed from 3 January to between 6 and 9 January. The Elon Musk backed company decided to go in for a later liftoff as problems had emerged with Falcon 9 rocket’s fairing.

     

    If ISRO’s GSLV-D5 successfully plants GSAT- 14 into orbit, it is likely to have a beneficial spinoff which it badly needs. It could lead to orders to build more rockets that can carry payloads of up to four tonnes. Till now ISRO has been using the Polar Satellite Launch Vehicle (PSLV) that carries loads of around a tonne.

     

    The mission will be telecast live on Doordarshan and on the web from 3: 52 pm on Sunday.

  • Rs 800 crore earmarked for two communication satellites in current year

    Rs 800 crore earmarked for two communication satellites in current year

    NEW DELHI: A budget of Rs 800 crore has been set aside for the launch of the GSAT 15 and GSAT 16 communication satellites during 2013-14.

    However, the total budget for GSAT-15 is Rs 859.5 crore and the figure for GSAT-16 is Rs 865.5 crore.

    GSAT-15 is a geostationary communication satellite which will carry 24 Ku-band transponders and one GAGAN (GPS Aided Geo Augmented Navigation) payload. GSAT-15 satellite will support the existing Direct-To-Home (DTH) and Very Small Aperture Terminal (VSAT) services in the country and the GAGAN payload will be a part of GAGAN space segment to provide better air traffic management over Indian Air Space.

    GSAT-16 is a geostationary communication satellite which will carry 24 C-band, 12 Ku-band and 12 Upper Extended C-band transponders. GSAT-16 satellite will support satellite based telecommunication, television, VSAT and other services in the country.

    GSAT-15 and GSAT-16 satellites are targeted for launch during the 2014-16 timeframe. The two satellites were approved in July this year, Minister of State in Prime Minister’s Office V Narayansamy told Parliament.

    The revenue earned by ANTRIX Corporation, the commercial arm of the department, through leasing of INSAT/GSAT transponders during the year 2012-13 is approximately Rs 482.67 crore.

    This revenue accrues from service providers of Direct-To-Home (DTH) services, TV Uplink services, Digital Satellite News Gathering (DSNG) services and Very Small Aperture Terminal (VSAT) services. This revenue does not include the capacities provided to various societal applications such a tele-education, tele-medicine, Village Resource Center, Disaster Management and part of public broadcasting services, which are not of the nature of revenue-earning services.

    At present, there are nine operational INSAT/GSAT communication satellites: INSAT-3A, INSAT-3C, INSAT-3E, INSAT-4A, INSAT-4B, INSAT-4CR, GSAT-8, GSAT-10 and GSAT-12. The total number of transponders available at present from these satellites is 195 operating in C, Extended C, Ku, and S-bands.

    Transponders on communication satellites are leased to users after the launch and operationalisation of the satellite. The Department of Space leases the transponders on INSAT/GSAT satellites through ANTRIX.
