What is discussed under Geo-Imaging Satellite EOS 03 UPSC ?
- About the launch
- GSAT
Why in News ?
Geo-imaging satellite EOS-03 is scheduled for launch in third quarter of 2021.
- Geo-imaging satellite will help in near-real time monitoring of natural disasters like floods & cyclones.
- EOS-03 would also enable monitoring of water bodies, crops, vegetation condition, forest cover changes etc.
Key Facts
- The satellite would enable near-real time monitoring of natural disasters like floods & cyclones.
- The first developmental flight of Small Satellite Launch Vehicle or SSLV is scheduled in the fourth quarter of 2021 from Satish Dhawan Space Centre, Sriharikota.
- ISRO’s vast experience in Solid propulsion and heritage of proven design practices has enabled SSLV to be developed as a cost-effective, three stage, all-solid launch vehicle with a payload capability of 500 kg to 500 km planar orbit or 300 kg to Sun Synchronous Polar Orbit.
- SSLV is ideal for on-demand, quick turn-around launch of small satellites.
- The major technologies developed as part of realization of SSLV are flexible nozzle control with electro-mechanical actuators for all stages, miniaturized avionics and a velocity trimming module in the upper stage for precise satellite injection.
- About the satellite
- Indian earth observing satellite operating from geostationary orbit to facilitate continuous observation of Indian sub-continent, quick monitoring of natural hazards and disaster.
- GISAT carries an imaging payload consisting of of multi-spectral (visible, near infra-red and thermal), multi-resolution from 50 m to 1.5 km.
- It will provide pictures of the area of interest on near real time basis including border areas.
- GISAT payload consists of
- 700 mm Ritchey-Chretien telescope based on the Cartosat 2 design
- Array detectors in VNIR, SWIR and LWIR bands
- Camera electronics and data handling system
- Electronically steerable transmit antenna system
- High agility platform to enable large payload steering requirements
