The rocket took off from the First Launch Pad at the Sriharikota Space Centre at 15:25 hours which is 3:25 according to the Indian Standard Timing. It is the QL variant of the PSLV.
The first satellite of the RISAT-2B series was launched earlier this year replacing RISAT-2, which went out of commission. Later this month another satellite of the RISAT-2B will be launched following the RISAT-2BR1.
According to the experts, these satellites will be helping in keeping a quick check on infiltration by providing 24/7 surveillance across the border. The synthetic aperture radar (SAR) equipped in these satellites enables clicking pictures of the earth during the day and night, irrespective of the cloud conditions.
Apart from Indian satellite, the satellites carried by the PSLV will be three from the US (multi-mission Lemur-4 satellites, technology demonstration Tyvak-0129, earth imaging 1HOPSAT), and one each from Israel (remote sensing Duchifat-3), Italy (search and rescue Tyvak-0092) and Japan (QPS-SAR, a radar imaging earth observation satellite).
