EOS-1 (previously known as RISAT-2BR2) is an imaging mission of ISRO using an active SAR (Synthetic Aperture Radar) imager to provide continuity of service for RISAT-2. The objective of the RISAT mission is to use the all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, and flood monitoring, but also for military surveillance. Flight also carries 9 rideshare payloads, including Lithuanian NanoAvionics R2 satellite - pathfinder for their M6P cubesat platform, 4 KSM satellites of Kleos Space for a maritime geolocation constellation, and 4 Lemur satellites for Spire.
