About RISAT-1A ISRO Mission 2020 Launch


RISAT-1A

Radar Imaging Satellite 1A, or RISAT-1A, is a planned remote sensing satellite that is similar in configuration to RISAT-1. The satellite is being developed by Indian Space Research Organisation (ISRO). RISAT-1A will be 6th in series of RISAT satellites. It will be a land based mission with primary application in terrain mapping and analysis of land, ocean and water surface for soil moisture.

Payload metrics are defined by the following parameters and areas of study
CategoryParameters
LandAlbedo and reflectance
Soil moisture
Vegetation
Multi-purpose imagery
OceanOcean topography/currents
Snow & IceIce sheet topography

Application

Active Microwave Remote Sensing provides cloud penetration and day-night imaging capability. These unique characteristics of C-band (5.35GHz) Synthetic Aperture Radar enable applications in agriculture, particularly paddy monitoring in kharif season and management of natural disasters like flood and cyclone.
