  • Ministry: Department of Science
  • Launched on- 22nd May 2019
    India’s third Radar imaging satellite RISAT-2B
  • Launching vehicle- Polar Satellite Launch Vehicle (PSLV-C46)
  • Launching station- Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota in Andhra Pradesh

About:

  • RISAT-2B is a Radar imaging earth observation satellite which is indigenously developed by Indian Space Research Organisation (ISRO)
  • The satellite is placed in an inclined orbit, 37 degrees to the equator to increase the number of imaging angles and opportunities and is being operated in X band

Features:

  • Effective for whole day operation during day/night/all weather conditions
  • Allows high-resolution spot imaging of any location of interest
  • It is a Synthetic Aperture Radar (SAR): SAR is a form of Radar that creates 2-dimensional 0r 3-dimensional imaging of objects, for example, landscape.
  • RISAT-2B provides RADAR imaging modes of 1m x 0.5m resolution and 0.5m x 0.3m resolution that are very high resolutions.
  • It has vast ranging applications including agriculture, disaster management, geosciences, forestry, crops, hydrology, and Cryosphere

Background:

  • RISAT-2B is India's 3rd radar imaging satellite program after RISAT-2 launched in 2009 (before RISAT-1) and RISAT-1 launched in 2012
  • RISAT-2 is the first radar observation satellite India has launched in 2012 designed to monitor India's borders
  • RISAT-1 was second in series and focused on natural resources management only
