RISAT-2B or Raar Imaging Satellite-2B was successfully launched by the Indian Space Research Organisation (ISRO) at the early dawn hours around 5 AM from the Satish Dhawan Space Centre from Sriharikota by the reliable launch vehicle PSLV-46 on Wednesday.

RISAT-2B will replace RISAT-2 earlier launched by ISRO in 2009.

RISAT-2B satellite will help capture images by sending radio signals as a camera flash which will provide a major improvement in surveillance, agriculture, forestry and disaster management.

ISRO Chairman K Sivan labeled the satellite launch as “very, very important mission for India. It is an excellent satellite with hi-fi earth observation.”

The RISAT-2B is a much improved satellite with ‘synthetic aperture radar’ sensor which is capable of sending hundreds of radio signals towards the desired object to create a radio image. This radio image can be transformed into a real image with the help of computers.

The use of radio waves in the RISAT-2B for image capture makes it capable to pierce through clouds, dust or any other atmospheric elements even in day or night.

RISAT-2B is the third such satellite in series by ISRO with the delayed RISAT-1 in 2012 which is now non-operational.
