EOS-03:
Context:
The Indian Space Research Organisation (ISRO) is scheduled to launch the geo-imaging satellite for earth observation EOS-03 in the third quarter of 2021.
- EOS-03 It is an earth observation satellite.
- Last year, ISRO launched EOS-01 which is nothing but another Radar Imaging Satellite (RISAT) that will work together with RISAT-2B and RISAT-2BR1.
Applications:
- It would enable near real-time monitoring of natural disasters like floods and cyclones.
- It is capable of imaging the whole country four-five times daily.
- It would also enable monitoring of water bodies, crops, vegetation condition, forest cover changes.
Advantages of radar imaging over optical instruments:
Radar imaging is unaffected by weather, cloud or fog, or the lack of sunlight. It can produce high-quality images in all conditions and at all times.
Other earth observation satellites launched by ISRO include:
RESOURCESAT- 2, 2A, CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, OCEANSAT-2, Megha-Tropiques, SARAL and SCATSAT-1, INSAT-3DR, 3D, etc.
