About RISAT-2 satellite:
- It was launched on 20 April 2009 by a PSLV C-12 rocket following the 2008 Mumbai terror attacks.
- It was India’s first “eye in the sky” to keep surveillance on the country’s borders as part of anti-infiltration and anti-terrorist operations.
- It was also used to track enemy ships at sea.
- The main sensor of RISAT-2, which was able to observe in all weather conditions day and night, was Israel Aerospace Industries’ X-band Synthetic Aperture Radar.
- It carried 30 kg of fuel for an initial designed life of four years.
- Due to proper maintenance of orbit and mission planning by the spacecraft operations team in ISRO and by economical usage of fuel, RISAT-2 provided very useful payload data for 13 years.
