    Congratulations ISRO | ISRO Launched PSLV -C15 Successfully

    This is a guest post by Mahender who blogs at StepsandTips. If you would like to write for NiharsWorld, check our guest posting guidelines.


    Indian Space Research Organization (ISRO) has successfully launched PSLV-C15 with five Satellites:

    1. CARTOSAT-2B
    2. ALSAT-2A
    3. AISSAT-1
    4. TISAT-1
    5. STUDSAT

    PSLV – C15 was launched from the first Launch Pad at Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, in the Nellore district of Andhra Pradesh.

    What is PSLV..?

    Polar Satellite Launch Vehicle (PSLV) was initially designed by ISRO to place 1,000 Remote Sensing (IRS) satellites into 900 km polar Orbits. Since its first successful flight in October 1994, PSLV was successively enhanced from 850 kg to previous flight (sixteenth) on September 23, 2009, PSLV 960 kg remote sensing satellite Oceansat-2 and six nanosatellites of abroad into a 728 km polar Sun Synchronous Orbit.

    About PSLV-C15.

    PSLV - C15
    PSLV-C15 employs the ‘Core Alone’ version of PSLV. PSLV-C15 is the sixth flight of the ‘core alone’ version of PSLV. One important modification in PSLV-C15 compared to the previous flight is the use of a Dual Launch Adopter (DLA) to carry two large satellites.

    Launch Details


    Today 12th July, 2010 , In its seventeenth flight (PSLV-C15), ISRO’s Polar Satellite Launch Vehicle successfully launched five satellites.

    1.CARTOSAT-2B

    The 694 kg Indian remote sensing satellite CARTOSAT-2B, which is its main payload. CARTOSAT-2B is a state-of-the art remote sensing satellite and the seventeenth remote sensing satellite of India. Data from the satellite will find applications in cartography at cadastral level, urban and rural infrastructure development and management, as well as Land Information System (LIS) and geographical Information System (GIS). The satellite will be placed in a 630 km high polar Sun Synchronous Orbit.

    Cartosat 2b01

    CARTOSAT-2B carries a state-of-the-art Panchromatic camera (PAN) that takes black-and-white pictures in the visible region of the electromagnetic spectrum. The imagery will have a spatial resolution of 0.8 meter. The camera covers a swath (geographical strip of land) which The satellite also carries a Solid State Recorder with a capacity of 64 Giga Bits to store the images taken by its camera. These images can later be transmitted when the satellite comes within the visibility of a ground station.is 9.6 km wide.

    The satellite’s health will be continuously monitored from the Spacecraft Control Center at Bangalore with the help of ISTRAC network of ground stations at Bangalore, Lucknow, Mauritius, Biak in Indonesia, Svalbard in Norway and Troll in Antarctica.

    CARTOSAT-2B’s Applications:

    The multiple spot scene imagery sent by CARTOSAT-2B’s PAN will be useful for village level/cadastral level resource assessment and mapping, detailed urban and infrastructure planning and development, transportation system planning, preparation of large-scale cartographic maps, preparation of micro watershed development plans and monitoring of developmental works at village/cadastral level. Besides, CARTOSAT-2B’s imagery can be used for the preparation of detailed forest type maps, tree volume estimation, village/cadastral level crop inventory, town/village settlement mapping and planning for comprehensive development, canal alignment, rural connectivity assessment, planning new rural roads and monitoring their construction, coastal landform/land use and coral/mangrove mapping and monitoring of mining activities. Besides CARTOSAT-2B which is a main payload, PSLV-C15 will also carry four small satellites as auxiliary payloads.

    2.ALSAT-2A

    ALSAT - 2A
    ALSAT-2A is a 116 kg small remote sensing satellite of Algeria.

    3.AISSAT-1

    Two Nanostats NLS-6.1 and AISSAT-1 weighing 6.5 kg built by Space Flight Laboratory of the University of Toronto, Canada.
    AISSAT-1

    4.TISAT-1

    TISAT-1

    NLS-6.2 TISAT-1 weighing one kg and built by University of Applied Sciences of Switzerland – are for testing various satellite technologies.

    5.STUDSAT

    STUDSAT is a picosatellite weighing less than 1 kg built by a consortium of seven Engineering colleges in Bangalore and Hyderabad.

    Consortium of Project STUDSAT

  • 1.Nitte Meenakshi Institute of Technology
  • 2.BMS Institute of Technology (BMSIT), Bangalore
  • 3.Chaitanya Bharathi Institute of Technology (CBIT), Hyderabad
  • 4.Institute of Aeronautical Engineering (IARE), Hyderabad
  • 5.M S Ramaiah Institute of Technology (MSRIT), Bangalore
  • 6.RV College of Engineering (RVCE), Bangalore
  • 7.Vignan Institute of Technology & Science (VITS), Hyderabad
  • STUDSAT is the first picosatellite developed in the country.Weighing about 650 gm, STUDSAT has the primary objective of promoting space technology in educational institutions and encourage research and development in miniaturized satellites, establishing a communication link between the satellite and the ground station, capturing the images of earth with a resolution of 90 meters and transmitting the payload and telemetry data to the earth stations.
