  Indian Remote Sensing satellite From Wikipedia, the free encyclopediaJump to:navigation, search  Indian Remote Sensing satellites ( IRS ) are a series of Earth Observation satellites, built, launched and maintained byIndian Space Research Organisation The IRS series provides many remote sensing services to India Contents [hide   ] • 1 IRS System • 2 IRS data applications • 3 IRS launch log • 4 Future IRS launches • 5 Satellite data acquisition and processing • 6 References • 7 See also • 8 External links   [edit] IRS System Following the successful demonstration flights of Bhaskara-1 and Bhaskara-2 satellites launched in 1979 and 1981, respectively, India began to develop the indigenous Indian Remote Sensing (IRS) satellite program to support the nationaleconomy in the areas of agriculture, water resources, forestry and ecology, geology, water sheds, marine fisheries andcoastal managementTowards this end, India established the National Natural Resources Management System (NNRMS) for which the Department of Space (DOS) is the nodal agency, providing operationalremote sensing data services [1] Data from the IRSsatellites is received and disseminated by several countries all over the world With the advent of high-resolution satellitesnew applications in the areas of urban sprawl, infrastructure planning and other large scale applications for mapping havebeen initiatedThe IRS system is the largest constellation of remote sensing satellites for civilian use in operation today in the world [2] With the launch of  CARTOSAT-2A [3]  ,the constellation now has eight satellites in operation – IRS-1D, OCEANSAT-1,Technology Experiment Satellite(TES), RESOURCESAT-1, CARTOSAT-1, CARTOSAT-2 and the latest CARTOSAT-2A  and IMS-1 All these are placed in polar sun-synchronous orbit and provide data in a variety of spatial, spectral and temporal resolutions [edit   ] IRS data applications Data from Indian Remote Sensing satellites are used for various applications of resources survey and management under the National Natural Resources Management System(NNRMS) Following is the list of those applications: • Preharvest crop area and production estimation of major crops • Drought monitoring and assessment based on vegetation condition • Flood risk zone mapping and flood damage assessment • Hydro-geomorphological maps for locating underground water resources for drilling well • Irrigation command area status monitoring • Snow-melt run-off estimates for planning water use in down stream projects • Land use and land cover mapping • Urban planning • Forest survey • Wetland mapping  • Environmental impact analysis • Mineral Prospecting • Coastal studies • Integrated Mission for Sustainable Development (initiated in 1992) for generating locale-specific prescriptionsfor integrated land and water resources development in 174 districts [edit] IRS launch log The initial versions are composed of the 1 (A,B,C,D) The later versions are named based on their area of applicationincluding OceanSat, CartoSat, ResourceSat Some of the satellites have alternate designations based on the launchnumber and vehicle (P series for

planned byISRO to be launched next strengthening the fleet of IRS satellites and widening their applications: [2][4] • RISAT (Radar Imaging Satellite) : A microwave remote sensing mission with Synthetic Aperture Radar (SAR)operating in C-band and having a 6 x 2 meter planar active array antenna based on trans-receiver modulearchitecture SAR is an all weather-imaging sensor capable of taking images in cloudy and snow coveredregions and also both during day and night RISAT weighs 1,750 kg • RESOURCESAT-2 : It will have imaging sensors similar to RESOURCESAT-1 Payload electronics have beenminiaturised to reduce the overall weight RESOURCESAT-2 is planned for launch by PSLV in 2010 • RESEOURCESAT-3 : A follow on to Resourcesat-2, it will carry more advanced LISS-III-WS (Wide Swath)Sensor having similar swath and revisit capability as Advanced Wide Field Sensor (AWiFS), thus overcomingany spatial resolution limitation of AWiFS Satellite would also carry Atmospheric Correction Sensor (ACS) for quantitative interpretation and geophysical parameter retrieval It slated to be launched during 2011-12 [4] • CARTOSAT-3 :A continuation of Cartosat series , it will have a resolution 30 cm and 6 km swath suitable for cadastre and infrastructure mapping and analysis It would also enhance disaster monitoring and damageassessment It is slated to be launched during 2011-12 [4]   • OCEANSAT-3 : Oceasat-3 would carry Thermal IR Sensor, 12 channel Ocean Color Monitor, Scatterometer andPassive Microwave Radiometer IR Sensor and Ocean Color Monitor would be used in the analysis for operational Potential Fishing Zones Satellite is mainly for Ocean biology and sea state applications It is slatedto the launched aboard PSLV in 2012-13 [4] [edit] Satellite data acquisition and processing The National Remote Sensing Centre(NRSC) at Hyderabad is the nodal agency for reception, archival, processing and dissemination of remote sensing data in the country NRSC acquires and processes data from all Indian remote sensingsatellites like CARTOSAT-1, CARTOSAT-2, RESOURCESAT-1, IRS-1D, OCEANSAT-1 and TES as well as foreignsatellites like Terra, NOAA and ERS
