- PSLV-C46 which is the 48th mission of PSLV, will launch RISAT-2B from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota on 22nd May 2019.
- PSLV-C46 is the 14th flight of PSLV in ‘core-alone’ configuration i.e. without the use of solid strap-on motors. Polar Satellite Launch Vehicle is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits.
- RISAT-2B is a Radar imaging earth observation satellite. It will be placed into an orbit of 555 km at an inclination of 37 degree. The satellite possesses day and night as well as all-weather monitoring capability, thus helping in providing India with real-time information. The all-weather seeing feature is especially significant for security forces and disaster relief agencies.
- RISAT-2B is a part of the RISAT or Radar Imaging Satellite series of Indian radar imaging reconnaissance satellites built by ISRO. In 2012, ISRO launched India’s first indigenous all-weather radar imaging satellite, known as RISAT-1.
- Before RISAT-1’s launch, India depended on images from a Canadian satellite as existing domestic remote sensing spacecraft cannot take pictures of the earth during cloud cover.
