GSLV (Geosynchronous Satellite Launch Vehicle) is the largest launch vehicle developed by India.
|Number of Stages||3|
|Lift Off Mass||414.75 tonnes|
|First Flight||April 18, 2001|
GSLV-F10 will launch GISAT-1 (Geo Imaging Satellite-1) satellite from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, the date of Aug 12, 2021.
It will be continuously observe land, ocean and atmospheric parameters at relatively higher resolution ranging from 50-320 meters using appropriate spectral bands from different applications.
After reaching Geosynchronous transfer orbit it will be commanded from ground to reach it’s geostationary orbital slot by using own propulsion system. It is navegate over the indian subcontinent at 85.5 degrees east longitude. It will generate two-dimensional imagery by showing in to as east direction and stepping in north-south direction. The scan mode includes coverage of entire indian subcontinent landmass and oceans.
The mission life of satellite will be around 7 years. Imagery from GISAT-1 will be utilized for a host of applications, including;
- Crop monitoring at regional and national level
- Drought progression and assessment.
- Ocean and Coastal zone management
- Fog detection and warning
- Disaster management, dust monitoring, and many more.
Indial earth earth observation Satellite are the excellent example of the countri’s technological strength, enhancing the space technology for the development of the country.
|Orbital slot||85.50 E|
|Lift-off mass||2268 kg|
|Power generation||2280 W|
