RISAT-2BR1 is an ISRO X-band radar imaging satellite for agriculture, forestry and disaster management. PSLV-C48, the 50th PSLV flight, launched it on 11 December 2019.
RISAT-2BR1 carries an X-band radar that images the ground day and night and through clouds. ISRO uses it for agriculture, forestry and disaster management.
The satellite weighed 628 kg at lift-off and has a planned mission life of 5 years.
Its 3.6 m radial-rib antenna was folded for launch and unfurled in orbit, a deployment that took 9 minutes 12 seconds.
PSLV-C48 lifted off from the First Launch Pad at Sriharikota at 15:25 IST on 11 December 2019. It was the second flight of PSLV in the 'QL' form with four strap-on motors.
About 16 minutes after lift-off it placed RISAT-2BR1 in a 576 km orbit inclined at 37°. Nine commercial satellites from Israel, Italy, Japan and the USA flew with it.
The public satellite catalogue carries RISAT-2BR1 with an operational flag, in an orbit of about 554 × 573 km.
