EOS-O4 (formerly known as RISAT-1A) is a ISRO remote sensing satellite as a follow on to RISAT-1 and with similar configuration. The satellite is developed by the Indian Space Research Organisation (ISRO) and it is the sixth in series of RISAT satellites. It is a land based mission with primary application in terrain mapping and analysis of land, ocean and water surface for soil moisture.[3]
Satellite description
Synthetic aperture radar can be used for Earth observation irrespective of the light and weather conditions of the area being imaged.[4] The satellite carries a C-band synthetic-aperture radar (SAR) and has a liftoff mass of 1,710 kg (3,770 lb).[2]
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
EOS-4 was launched on the Polar Satellite Launch Vehicle (PSLV-C52), at 00:29 UTC on 14 February 2022.[5][6]
