The Indian Space Research Organization (ISRO) successfully launched its advanced weather satellite INSAT-3DR using its GSLV-F05 from the spaceport of Sriharikota in Andhra Pradesh. The cryogenic engine used in the satellite was made in India.
This advanced meteorological satellite is configured with an imaging system, an atmospheric sounder, data relay as well as search and rescue transponders.
Other features include:
- Imaging in middle infrared band to provide night time pictures of low clouds and fog
- Imaging in two thermal infrared bands for estimation of sea surface temperature with better accuracy
- Higher spatial resolution in the visible and thermal infrared band
Earlier launches using this technology—GSLV-D5 and GSLV -D6—were a success. The GSLV class of satellites also includes EDUSAT, which is used for distance education and other academic purposes, reports Mint.
