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 3rd 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.[3]

Payloads

The satellite will carry Synthetic Aperture Radar which will operate at 5.35 GHz in C-band. Synthetic Aperture Radar can be used for earth observation irrespective of the light and weather conditions of the area being imaged.[4]

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

Spacecraft

RISAT-1A will be launch aboard Polar Satellite Launch Vehicle (PSLV) and will have liftoff of mass of 1,858 kilograms (4,096 lb)

Launch

RISAT-1A is planned to be launch in 2019[5]
