PSLV-C36 launches RESOURCESAT-2A
In its thirty eighth flight (PSLV-C36), ISRO’s Polar Satellite Launch Vehicle successfully launched the 1235 kg RESOURCESAT- 2A Satellite on 7 December 2016 from Satish Dhawan Space Centre SHAR, Sriharikota. This is the thirty seventh consecutively successful mission of PSLV.
After PSLV-C36 lift-off at 10:25 am IST from the First Launch Pad with the ignition of the first stage, the subsequent important flight events, namely, strapon ignitions and separations, first stage separation, second stage ignition, payload fairing separation, second stage separation, third stage ignition and separation, fourth stage ignition and cut-off, took place as planned. After a flight of 17 minutes 05 seconds, the vehicle achieved a polar Sun Synchronous Orbit of 824 km height inclined at an angle of 98.725 degree to the equator (very close to the intended orbit) and 47 seconds later, RESOURCESAT-2A was separated from the PSLV fourth stage. 3-Tier imaging system with Advanced Wide Field Sensor (AWiFS), Linear Imaging Self Scanner-3 (LISS-3) and Linear Imaging Self Scanner-4 (LISS-4) cameras. The AWiFS provides images with a sampling of 56 metres, a swath of 740 km and a revisit of 5 days whereas the LISS-3 provides 23.5 metre sampled images with 141 km swath and a repitivity of 24 days. LISS-4 provides 5.8 metre sampled images with 70 km swath and a revisit of 5 days.
With this launch, the PSLV has yet again demonstrated its reliability. The total number of satellites launched by India’s workhorse launch vehicle PSLV including the RESOURCESAT-2A has now reached 122, of which 43 are Indian and the remaining 79 are international.
PSLV remains the ISRO’s versatile launch vehicle for launching multiple satellites in polar SSOs, Low Earth Orbits (LEO) as well as Geosynchronous Transfer Orbit ( GTO) and sub GTO. With 36 successful launches, PSLV has emerged as the workhorse launch vehicle of ISRO and has been offered to launch satellites for international customers.
