    Default INSAT-4B ready for launch on 11 MARCH


    Insat-4B ready for launch on 11 March

    MUMBAI: Preparations are in the final stages for the launch of Isro's latest satellite, Insat-4B, on board Ariane-5 ECA launch vehicle from Kourou, French Guiana.

    The launch window for the Ariane-5, carrying Insat-4B and its co-passenger Skynet 5A of EADS Astrium, is fixed between 03:55 am and 04:28 am Indian Standard Time on 11 March (7:25 pm to 7:58 pm 10 March, in Kourou).

    Insat-4B is the second satellite to be launched in the Insat-4 series. Insat-4B carries 12 high power Ku-band transponders and 12 C-band transponders to augment the capacity for direct-to-home (DTH) television services apart from augmenting the Insat capacity for other communication and television services.


    The Master Control Facility (MCF) at Hassan in Karnataka is in readiness to take control of Insat-4B soon after Ariane-5 places it in the Geosynchronous Transfer Orbit (GTO) of 250 km x 35,886 km.

    In the following days after launch, MCF will conduct orbit raising manoeuvres to take the satellite into the final 36,000 km circular Geosynchronous Orbit followed by deployment of solar arrays and antennas. Insat-4B will be positioned at 93.5 degree East longitude along with Insat-3A. This will be followed by in-orbit test of the communication payloads. MCF will also carry out regular operations and control of the satellite during its service life.

    The Rs 3 billion telecom satellite, which is identical to Insat-4A, carries 12 Ku-band and 12 C-band transponders. European space consortium Arianespace will carry out the launch. It will cost around $ 50 million.


    Kalanithi Maran's Sun Group has booked seven Ku-band transponders on Insat-4B for its soon to launch (DTH) service Sun Direct, while Prasar Bharati's free-to-air (FTA) package DD Direct Plus has booked five.

    Sun will be using MPEG-4 technology that will allow it to compress more TV channels per transponder. While MPEG-2 can pack in around 12 channels, the advanced compression technology will be able to accommodate over 20 channels.

    Sun may consider itself lucky that the launch of Insat-4C satellite failed in July 2006 after the rocket carrying it veered off course and exploded. Sun had booked six Ku-band transponders (and one more for digital satellite news gathering) on it for its DTH service.

    By being located on the same satellite, Sun's subscribers will be able to access DD Direct's channels without it having to separately put them on its transponders.

    Live Transmission: Live Transmission of Insat-4B launch from Kourou will be available for Indian TV channel to relay the programme to their viewers. Details of live transmission are as follows:

    Date : Sunday, 11 March
    Time : 3:30 am to 5:15 am
    (Test Transmission 12:55 am to 1:25 am)
    Satellite: Asiasat-2
    Location: 100.5 deg. E
    Transponder : 7A
    Channel : 4
    Downlink : 3913 MHz
    Polarisation : Vertical
    Symbol Rate : 6.1113
    FEC : 3/4
    Kind of Signal : 9 MHz, DVB, PAL

    Yes.. obviously Sun should be cheap.. but will Zee, Sony and star allow them to be.......

    They will force Sun to carry their channels to all its users and thereby increasing its normal rate...... Just like Star and Sony did to Dishtv and that is why they increased rates of all zones from 180rs to 210rs and for south from 160rs to 210rs..

    anyhow lets see once it is launched.

    UPdated News for the Launch..........

    Bangalore: Countdown for Insat-4B launch

    Bangalore, March 10 (IANS) The countdown has begun for the launch of the telecommunications satellite Insat-4B, primarily meant for direct to home (DTH) television services, on Sunday from Kourou in French Guyana.

    Final preparations for the launch of the satellite on board the Ariane-5 are complete.

    G. Madhavan Nair, chairperson of the Indian Space Research Organisation (ISRO), satellite centre project director R.K. Rajangam and about 20 space scientists and technicians are camping at Kourou to witness the launch and coordinate the post-launch activities with their counterparts in India.

    As the second satellite in the Insat-4 series, the 3,025 kg Insat-4B is carrying 12 high power Ku-band (11-14 GHz) transponders and 12 C-band (4-6 GHz) transponders to augment the capacity for DTH television services and expanding the Insat capacity for other communication and broadcasting services.

    "The launch window for Ariane-5 ECA, carrying Insat-4B and another payload (Skynet 5A), has been fixed between 3:55 a.m. and 4:28 a.m. IST Sunday," a top ISRO official told IANS here.

    About 30 minutes after the launch, the Indian satellite will be placed in an elliptical geo-synchronous transfer orbit (GTO), with a perigee (nearest point to earth) of 250 km and an apogee (farthest point to earth) of 35,786 km.

    The inclination of Insat-4B's GTO will be 4.5 degree with respect to the equatorial plane. The spacecraft will be manoeuvred into the 36,000 km high circular geo-synchronous orbit (GSO) from Monday by firing its liquid apogee motor (LAM) in phases.

    "As the satellite nears the GSO, its dish shaped antenna reflectors and solar panels will be deployed and the satellite will be put in final 'three axis stabilised mode' to provide stability. In GSO, Insat-4B will be co-located with Insat-3A satellite at 93.5 degree east longitude," the official said.

    ISRO's Master Control Facility (MCF) at Hassan in Karnataka has been geared up to take control of the satellite after it is positioned in GTO. Besides conducting the in-orbit test of the communication payloads, the MCF will carry out regular operations and control the satellite during its 12-year life span.

    "The over three-tonne satellite has been built at the ISRO satellite centre in Bangalore at a cost of Rs.2.15 billion. The launch cost is estimated to be Rs.2.25 billion. The satellite has also been insured for Rs.600 million," the official disclosed.

    The solar panels of the 50-ft satellite can generate about 5,800 watt. Three lithium ion batteries of 100 ampere-hour (Ah) capacity will generate power to maintain the satellite's key functions during eclipse periods.

    The 24-year Indian National Satellite (Insat) system has revolutionised the communications system spanning telecom, meteorology, radio and television broadcasting and other vital services such as education, health, agriculture and business.

    "The Insat system has become the largest domestic communication satellite system in the Asia-Pacific region, with nine spacecraft, including Kalpana-1, Gsat-2, Edusat and Insat-4A in service, with 175 transponders in C, extended C and Ku bands," the official noted.

    ISRO plans to launch Insat-4CR in mid-2007 as a replacement of the Insat-4C that was lost following the crash of the GSLV in July last year from the Satish Dhawan space centre at Sriharikota in Andhra Pradesh. It is set to carry 10-12 Ku-band transponders.

    As the 175th launch of the European Space Agency's (ESA) Ariane programme and 31st launch of Ariane-5, the latest launch vehicle is also carrying Skynet-5A, a military secured communications satellite built by the Paris-based EADS Astrium
