  • ISRO scientists meet PM; present first imageries of Cartosat-1

    BANGALORE: Indian Space Research Organisation (ISRO) chairman G Madhavan Nair and a team of senior scientists have presented the first imageries from the recently launched CARTOSAT-1 satellite to the Prime Minister today.
     
    Nair made a presentation to the PM on the PSLV C6/ CARTOSAT-1/ HAMSAT mission operations, performance of launch vehicle PSLV, Cartosat-1 and Hamsat. PM was shown the first pictures received from the satellite over Punjab and Gujarat, with 2.5 metre resolution stereoscopic camera and the digital terrain model processed from the satellite pictures over Gujarat.

    Prime Minister while evincing keen interest in the details depicted in the imagery, congratulated ISRO scientists for their outstanding achievement.

  • Cartosat-1 cameras tested, Hamsat starts service

    MUMBAI: Imageries from the two panchromatic cameras on board Indian Space Research Organisation’s (ISRO) latest satellite, Cartosat-1 were received at National Remote Sensing Agency’s Data Reception Station at Shadnagar, near Hyderabad. Detailed analysis confirms the excellent performance of the cameras.
     

    Cartosat-1 carries two panchromatic cameras that take black-and-white stereoscopic pictures in the visible region of the electromagnetic spectrum. The imageries have a spatial resolution of 2.5 metre and cover a swath of 30 km.

    ISRO, meanwhile, has claimed that as many as four countries have shown interest in using Cartosat-1’s applications. The four countries are China, Japan, Germany, and the UAE.

    The second satellite launched, Hamsat had its UHF/VHF (Mode-B) transponder switched on 6 May. With this, Amateur Radio Operators (Ham) worldwide have witnessed hectic activities. Hams are sending their feedback on the performance of the satellite. E-mails have been received from Hams in India, Canada, USA, Malaysia, Australia, Germany, Brazil, UK, Italy and Spain, confirming excellent quality of transmission by Hamsat both in terms of power and clarity, states an Isro release.
     
     

    The 42.5 kg Hamsat, built by Isro as a contribution to Ham operators, was launched as a piggyback satellite along with Cartosat-1. The satellite was oriented properly in its orbit and stabilized at the specified spin rate of 4.3 rpm on 5 May.

    Reportedly, Cartosat-1 has cost approximately Rs 2.5 billion, while Hamsat cost Rs 30 million. Another Rs 750 million was spent on the launch vehicle. The newly built launching facility at Sriharikota has cost the nation approximately Rs 4 billion.

  • Cartosat-1, Hamsat in orbit; fillip to mapping & Ham radio

    MUMBAI: The Indian Space Research Organisation (Isro) has successfully launched India’s heaviest remote sensing satellite Cartosat-1 and lightweight Hamsat from the newly set up Second Launch Pad at the Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh.
     

    The Polar Satellite Launch Vehicle (PSLV) soared into the sky at 10.14 am and placed the satellites in the 618 km polar Sun Synchronous Orbit (SSO) at 10.32 am. Both the satellites have been placed in polar Sun Synchronous Orbit (SSO) at an altitude of 632 x 621 km with an inclination of 97.8 deg with respect to the equator. The solar panels of Cartosat-1 were deployed soon after its injection into orbit.

    The 1560 kg Cartosat will be used for mapping applications while the 42.5 kg Hamsat, a microsatellite, will help expand bandwidth to help amateur radio operators around the world.
     
     
     

    Intended for cartographic applications, Cartosat-1 carries two panchromatic cameras that take black-and-white stereoscopic pictures in the visible region of the electromagnetic spectrum. The imageries will have a spatial resolution of 2.5 metre and cover a swath of 30 km. The imageries will be useful for generating digital elevation maps for urban and rural development, land and water resources management, disaster assessment, relief planning and management and environmental impact assessment. Cartosat-1 also carries a Solid State Recorder with a capacity of 120 Giga Bits to store the images taken by its cameras.

    Hamsat will meet the long felt need of the Amateur Radio Operators in the South Asian region who possess the required equipment and operate in the UHF/VHF band based Satellite Radio Communication. One of the transponders of Hamsat has been developed indigenously involving Indian amateurs, with the expertise of Isro and the experience of Amsat-India. The second transponder has been developed by a Dutch amateur radio operator and graduate engineering student at Higher Technical Institute, Venlo, Netherlands.

    Hamsat is India’s contribution to the international community of Amateur Radio Operators. This effort is also meant to bring Isro’s Satellite services within the reach of the common man and popularise Space Technology among the masses.

    With the successful launch of Cartosat-1 and Hamsat today, PSLV has reiterated its reliability and versatility for launching satellites of different weight classes precisely into specified orbits, says an Isro statement.
