    If transponder space unavailable on Insat-4B, Sun might opt for Measat3

    MUMBAI: A day after the unfortunate failure of the GSLV-F02 launch rocket carrying the Insat-4C communication satellite, it is not just India’s space establishment that has been forced to relook its plans.

    For Kalanithi Maran’s southern broadcast network Sun Group, the mishap could well mean that the launch of its direct-to-home (DTH) service sees a change of satellite operator. Sun TV had booked seven high-power Ku-band transponders, six for DTH and one for DSNG (digital satellite news gathering), of the total 12 carried by the Indian Space Research Organisation’s Insat-4C.

    The big question now is this: If Isro is not able to provide Ku-band transponder space for his DTH venture Sun Direct, will Maran opt for an alternative satellite like Malaysia’s soon-to-be-launched Measat-3?

    Maran already has a running relationship with Measat’s parent company Astro, having stitched a deal last year for a $25 million joint venture to originate, aggregate and distribute television programming and channels for a global audience. Measat Broadcast Network Systems is a subsidiary of Astro company which has a 20-year exclusive licence for DTH transmission in Malaysia.

    Measat has scheduled a September launch for the Measat-3 satellite. The satellite will be shot into space atop a Proton rocket from the Baikonur Cosmodrome in Kazakhstan. Measat-3 will have 24 Ku-band transponders and has been designed to provide capability for data services and DTH applications in Malaysia, Indonesia, India and China.

    Maran, however, says he has got intimation from Isro that he will be provided with Ku-band transponders at the earliest. “Isro has assured us of providing alternate transponders to meet our DTH requirements. We have not made any request to Isro for taking space on Measat-3. We were, in any case, looking at a time frame between October-November,” the Sun Group promoter tells Indiantelevision.com.

    Has Maran been told which satellite will provide him the Ku-band transponders? “We will know from Isro in three to four days,” he says.

    For DTH providers who want to operate from foreign satellites, Isro will have to provide the approval and lease it out for them. Dish TV, for instance, is on NSS-6 with Isro’s backing as required by regulatory norms.

    For Isro’s commercial arm Antrix Corporation, hiring of foreign transponder space for a short time could be a possibility. There is a precedence of this having happened in the past.

    According to a report in Hindu Businessline, when Insat-2D failed, Isro bought transponder space on an Arabsat satellite. Isro has also provided temporary leases on Thaicom, GE-Americom, and even now on NSS, Businessline reported.

    At the moment though, Isro has not received any fresh proposal from Maran’s DTH company, Sun Direct TV, to lease out a satellite for them. Says Isro contract management and legal services director SB Iyer, “Sun has not asked us for a foreign satellite yet. The failure of Insat-4C is a brief setback which has put us behind 4-6 months. But we are recasting our programme by which we can accelerate the Ku-band capacity growth. We may be putting up larger satellites to boost the capacity.”

    So will Sun get space on Insat-4B, which is meant for Doordarshan’s DTH service like DD Direct Plus? “We haven’t taken any decision yet. DD, which is on NSS-6, has a low requirement,” says Iyer. Sun has asked up to eight transponders for its DTH service.

    Even if Sun gets Insat-4B, the launch of the satellite is expected to take place early next year. The commercial operations can, thus, commence only by the first quarter of next fiscal. “We have the flexibility to accommodate Sun. It is too early to comment on the steps we are going to take,” says Iyer.

  • GSLV to launch Insat-4C on 10 July

    GSLV to launch Insat-4C on 10 July

    MUMBAI: The countdown is on for the launch of GSLV-F02, which will be carrying the state-of-the-art communication satellite Insat-4C into space. The launch is expected to take place around 4:30 pm on Monday, 10 July, the Indian Space Research Organisation announced today.

    Preparations for the launch are proceeding satisfactorily at Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota from the second launch pad. The launch vehicle systems have been integrated and checked out, Isro said in a statement issued today.

    Insat-4C was transported from Isro Satellite Centre, Bangalore to SDSC SHAR in the first week of June 2006 and since then, it has undergone detailed checks. After propellant filling, the spacecraft has been integrated with GSLV.

    The Mission Readiness Review is planned on 6 July, 2006 followed by the meeting of Launch Authorisation Board which will clear the launch. In the next few days, a complete checkout of the fully integrated launch vehicle along with satellite will be carried out. The final countdown and fuel filling for the liquid propellant stages are expected to commence on the morning of 9 July.

    Insat-4C is the second satellite in the Insat-4 series. The first, Insat-4A, was launched in December last year, from the spaceport of Kourou in French Guiana by an Ariane5 vehicle, which also carried the Meteosat weather Satellite for Eumetsat.

    Isro spokespersons have been pointing out that using indigeneous launch vehicles will result in a saving of about 30-40 per cent or Rs 1.5 billion in expenses per launch. With four satellites to be launched by GSLV Mark II and Mark III, the savings thus will be substantial. Isro will, however, be using the services of Arianespace to launch the Insat 4B satellite from Kouru next year.

    “With the commissioning of the Rs 3.5 billion ($75million) second launch pad at Sriharikota, India is the only country to have such a state-of-the-art facility to launch different types of vehicles Ranging from PSLV (polar satellite launch vehicle), GSLV Mark-1, GSLV Mark-II to the upcoming GSLV Mark-III in the four-tonne class,” a top Isro official is reported to have said sometime back.

    It’s for the first time that India’s space agency is putting into orbit a two-tonne class satellite. Equipped with 12 high-powered Ku band transponders (Like the earlier Insat-4A), the 2,180 kg spacecraft is designed for a mission life of 10 years.

    Insat-4C is designed to provide direct-to-home (DTH) television services, facilitate video picture transmission (VPT) and digital satellite news gathering (DSNG) as well as to serve the National Informatics Centre (NIC) for its VSAT connectivity. The 2,168 kg Insat-4C has a mission life of ten years.

    Insat-4C will be used for broadcasting 150 TV channels through the DTH platform. Kalanithi Maran’s Sun Group has booked space on Insat 4C for its DTH venture Sun Direct. All the Ku-band transponders on the Insat 4A satellite, meanwhile, have been leased to the Tata-Star consortium, which will soon be launching the Tata Sky DTH service.

    Other than Tata Sky and Sun Direct, there is also Anil Ambani’s DTH venture Reliance Bluemagic, which will be rolling out in due course.

    At present, DD Direct Plus managed by the pubcaster Prasar Bharati and the Subhash Chandra owned Dish TV are the two operators offering DTH services in the country.

    Salient features of Insat-4C:

    Orbit: Geostationary (74 degree East Longitude)
    Co-located with Insat-3C, KALPANA-1 and EDUSAT
    Lift-off Mass: 2,168 kg
    Mission: 10 years
    Communication Payloads: 12 Ku-band 36 MHz bandwidth Transponders employing 140 W Travelling Wave Tube Amplifiers (TWTAs) to provide an Effective Isotropic Radiated Power (EIRP) of 51.5 dBW at Edge of Coverage (EOC) with footprint covering Indian mainland; Ku-band Beacon as an aid to users to lock on to the satellite signal
