- Abstract
RISAT-1 is the first indigenous active Radar Imaging Satellite launched by Polar Satellite Launch Vehicle (PSLV) in April 2012 from Sriharikota. It carries Cband Synthetic Aperture Radar (SAR) payload which can operate at various values of resolution and swath for various applications. RISAT-1 is the heaviest and high-power satellite with many new technologies to support the SAR payload and the associated elements. RISAT-1 operates at polar sun-synchronous orbit of 536 km altitude with the inclination of 97.554° and it is designed for 5 years lifetime. Performance of the spacecraft system and the SAR payload is satisfactory. This article outlines the architecture, design and onorbit performance of RISAT-1.
