Mission details:

• RISAT 2 (Radar Imaging Satellite) is a Tecsar-class radar imaging satellite; was launched for ISRO and manufactured by Israel Aircraft Industries, bought from Israel to make up for delays in the Indian-built RISAT-1. It is the first satellite to be manufactured by IAI for a foreign customer.
• First Indian dedicated military surveillance satellite; rushed out after attack on Mumbai.
• Body of the satellite is based upon the Ofeq/OptSat platform: box-shaped with a tapering propulsion module at the top, 1.2 metres base diameter, 0.7 metres top diameter and 2.3 metres high, plus two vanes of solar panels which are deployed in orbit, plus a dish-shaped radar antenna.
• The PSLV took off at 01:15 UTC from the Satish Dhawan Space Center on Sriharikota Island north of Chennai, and the first three stages placed the PS4 fourth stage with its payloads on a suborbital trajectory of about -1000 x 560 km x 20 deg, heading east to avoid Sri Lanka. After a few minutes coast, the package reached apogee at 0130 UTC over the equator at 116 deg E, and the PS4 yawed to burn the vehicle into a more southerly-bound 400 x 552 km x 41.1 deg orbit. (One source suggests the yaw burn may be at around 5 deg N rather than on the equator). The third stage reentered over the ocean east of Australia at around 0146 UTC. After a depletion burn the fourth stage is in a slightly higher 453 x 559 km orbit.
• RISAT-2 separated from the PS4 at 01:32 UTC, and two minutes later Anusat, a small 40 kg imaging satellite from Anna University in Chennai, was also ejected from the stage.
