In News: India’s Polar Satellite Launch Vehicle (PSLV-C46) successfully launched RISAT-2B satellite
RISAT-2B is radar imaging earth observation satellite weighing about 615 kg; the all-weather imaging satellite that boosts the capability to image earth resources as well as enhance surveillance and security.
Utility for India
The satellite is intended to provide services in the field of Agriculture, Forestry and Disaster Management. The RISAT, or radar imaging satellite, is equipped with a sensor known as ‘synthetic aperture radar’ that takes what are known as ‘radar images’. Globally, security agencies use the images and services of such satellites.
The radar imaging satellite can observe and image the earth from about 500 km. It is an improvement over the remote sensing satellites in natural resources observation and management.
The biggest advantage is that ground imageries can be collected during rains and despite dust, clouds or darkness and during all seasons, thus ensuring continuous and reliable data.
