The satellite will provide services in the field of Agriculture, Forestry and Disaster Management. SALIENT FEATURES OF RISAT-2BR1 Lift-off weight 628 kg Altitude 576 km Payload X-Band Radar Inclination 37 deg Mission Life 5 years The RISAT-2BR1 is follow on to RISAT-2B and has an X-band SAR with unfurlable radial rib reflector antenna of 3.6 meter diameter. RISAT-2BR1 can operate in different modes including Very High Resolution imaging modes of 1m x 0.5m resolution and 0.5m x 0.3m resolution[8] with swath of 5 to 10 km. Mass: 628 kg Orbit: 557 km (circular) at inclination of 37° Mission life: 5 years Launch: RISAT-2BR1 was launched aboard PSLV-C48 on 11 December 2019 at 09:55 UTC with nine other ride-sharing commercial satellites from First Launch Pad of SDSC SHAR. Launch vehicle used was QL variant of Polar Satellite Launch Vehicle with four PSOM-XL strap-ons and employed a 195 kg Dual launch Adapter (DLA) to accommodate primary and secondary payloads. After flight of 16 minutes 27 seconds, RISAT-2BR was separated from PSLV fourth stage (PS4) and injected into 576 km circular orbit with 37° inclination. After primary payload, DLA-Upper and subsequently nine other co-passenger satellites were separated. RISAT-2BR1 deployed it solar panels within 3 minutes after separation and deployed its 3.6 meter antenna on 0830 UTC, 12 December 2019.
