  Earth Observation System

Indian Remote Sensing (IRS) satellite system was commissioned with the launch of IRS-1A in the year 1988. Currently, eleven satellites are operational in orbit (Resourcesat-1, Resourcesat-2, Cartosat-1, Cartosat-2, Cartosat-2A, Cartosat-2B, RISAT-1, RISAT-2, Oceansat-2, Megha-Tropiques and SARAL). Though Resourcesat-1, Cartosat-1, Cartosat-2 and Cartosat-2A satellites have completed their design mission life in orbit, these satellites continue to provide imaging services to the users. Various instruments onboard these satellites provide data in varied spatial, spectral and temporal resolutions to cater to different user requirements in the country. The INSAT series of satellites with meteorological payloads operating from geostationary orbit provide data for generating various parameters, viz, cloud motion vectors, cloud top temperature, water vapour content, vertical profiles of temperature and humidity, facilitating weather forecasting, genesis of cyclones and their track prediction, etc. Currently, INSAT-3A, KALPANA-1 and INSAT-3D are providing meteorological data to the user community.
