EOS-04 or Earth Observation Satellite - 04 (formerly known as RISAT-1A) is an Indian Space Research Organisation Radar Imaging Satellite designed to provide high-quality images under all weather conditions for applications such as Agriculture, Forestry & Plantations, Soil Moisture & Hydrology and Flood mapping.[3][4] It is a follow on to RISAT-1 satellite with similar configuration. The satellite is developed by the ISRO and it is the sixth in a series of RISAT satellites.
