- Abstract
Over the last three decades, ISRO, India has achieved significant progress in design, development and operationalisation of many Remote Sensing Applications and Science Missions. The spacecraft developmental efforts in ISRO started with the successful realization and launch of Aryabhata, the first Indian scientific satellite launched by the Russian launcher. This followed the development of application oriented satellites namely Bhaskara-1 and Bhaskara-II and IRS series of satellites. Indian Remote Sensing Satellite IRS-1A/1B with Linear Imaging Self Scanning Sensors (LISS) was launched in March 1988 and August 1991 respectively. This was followed by IRS-P2 and IRS-P3 as opportunity payloads for PSLV Launch vehicle. The advanced spacecraft like IRS-1C/1D with high resolution panchromatic and multi-spectral sensors and medium resolution Wide Field Sensor (WIFS) was launched in 1995 and 1997 respectively. Realising the growing user demands and to meet the spatial, spectral and radiometric resolutions application requirements, ISRO has launched Oceansat-1 in May 1999, the most advanced Remote Sensing Satellites Resourcesat-1 in October 2003 and Cartosat-1 in May 2005. A dedicated Cartographic application satellite called Cartosat-2 was launched in January 2007 Having fulfilled the Remote Sensing needs of the country and the world, ISRO has also initiated the Planetary exploration activity. As a first step in the Planetary Space Science, Chandrayaan-1 is planned to be launched by July 2008 for the exploration of the moon, and also initiated the activities for Chandrayaan-2. In order to meet the growing demand and to provide the continuity of data to the remote sensing user community, ISRO has planned the continuity missions like Oceansat-2 and Resourcesat-2 with improved payload performance. In order to overcome the limitation of remote sensing data collection in the presence of cloud or fog, such is the situation during monsoon seasons, Radar Imaging Satellite (RISAT-1) using Synthetic Aperture Radar is being developed to provide day and night and all weather imaging capability to meet the agriculture, oceanography, forestry, geology and hydrology applications. ISRO is also planning a dedicated satellite called Megha-Tropiques for Climate /Atmospheric applications, to study the Oceanic winds, humidity profile, liquid water, clouds, and the radiation budget over the trophiques. In order to meet Space Astronomy interest of the scientists, ISRO is developing an Astronautical Observatory Satellite called Astrosat, which will serve as a National Observatory for many Astronomical observations. With the experiences in the development of many IRS satellite and commensurate with the development of Micro-electronics and light weight technologies, ISRO is planning series of micro and mini-satellites for many technological and application payloads for earth imaging, atmospheric and ocean studies and Space Science applications. One of the first of the micro-satellite series called MRS-1 with < 100 kg weight, carrying a multi-spectral and a hyper-spectral camera for agricultural application purposes is planned for launch by April 2008. The second of the series called Youthsat carries scientific payloads for studying solar radiation, ionospheric study and the airglow measurements of the earth’s upper atmosphere is planned for launch by end 2008. . The first of the mini satellite in the weight class of 300 to 400 kg called SARAL, is planned to provide data to better understand ocean circulation and its impact on climate. Thus, ISRO is continuously endeavoring to meet the aspirations of the whole human community of the world. In this paper a brief description of each mission and its application potential are given. *****
