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.
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.
Payload metrics are defined by the following parameters and areas of study
|Land||Albedo and reflectance|
|Snow & Ice||Ice sheet topography|
|Snow cover, edge and depth|
|Sea ice cover, edge and thickness|
RISAT-1A will be launched on the Polar Satellite Launch Vehicle (PSLV) and will have a liftoff mass of 1,858 kilograms (4,096 lb). RISAT-1A is planned to be launched on January 1st 2021 at the same time as Oceansat-3.
RISAT-1A is planned to be launched on TBD
