RISAT-2BR1

RISAT-2BR1 is an ISRO radar imaging Earth observation satellite in the RISAT programme, launched on 11 December 2019 aboard PSLV-C48 from Sriharikota.^[1] The satellite carries an X-band SAR-X synthetic aperture radar operating at 9.59 GHz, delivering 1 to 8 m spatial resolution across 10 to 50 km swath widths depending on imaging mode.^[2] The mission operates in a low Earth drifting orbit; ISRO recorded an injection orbit of 576 km while WMO OSCAR notes a later operational altitude of approximately 555 km, both at 37 degree inclination.^[1]^[3] WMO records the satellite as operational as of a February 2026 update,^[3] beyond the 5-year design life stated at launch.^[1] Mass was reported as 628 kg by ISRO and 615 kg by WMO OSCAR.^[1]^[3] Applications include agriculture monitoring, forestry assessment, disaster management, and reconnaissance, with data distributed offline through NRSC and received at appointed ground stations.^[1]^[3]
