Radar Imaging Satellite-1A, or RISAT-1A, is a planned remote sensing satellite as a follow on to RISAT-1 and with similar configuration. The satellite is being developed by Indian Space Research Organisation (ISRO) and it 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.[2]

Satellite description

Synthetic aperture radar can be used for Earth observation irrespective of the light and weather conditions of the area being imaged.[3] The satellite will carry a C-band synthetic-aperture radar (SAR) and will have a liftoff mass of 1,858 kg (4,096 lb).[1]

Payload metrics are defined by the following parameters and areas of study:

Category Parameters
Land Albedo and reflectance
Soil moisture
Vegetation
Multi-purpose imagery
Ocean Ocean topography/currents
Snow & Ice Ice sheet topography
Snow cover, edge and depth
Sea ice cover, edge and thickness

Launch

RISAT-1A will be launched on the Polar Satellite Launch Vehicle (PSLV-C52). RISAT-1A is planned to be launched in September 2021.[4]
