The main objective of Remote Sensing satellites is to gather information about earth's physical, chemical and biological systems.  The first operational remote sensing satellite IRS-1A was launched in the year 1988.  It was built on I-1K platform. Since then, many Earth Observation satellites have been launched for studying land, ocean and atmosphere.Currently ISRO operates Resourcesat (Land applications), RISAT (All weather SAR satellite), Oceansat (Ocean applications) and Cartosat (High resolution/ large mapping application) series of satellites.  ISRO also has built mini satellite platforms namely IMS-1, IMS-2 and IMS-3 to cater to small satellite needs.
