7. Question
1 pointsCategory: Science and TechnologyIndian Space Research Organisation (ISRO) is creating a GEO Imaging Satellite (GISAT) which it plans to launch. Consider the following statements about it:
- The satellite will carry a GEO Imager with multi-spectral, multi-resolution imaging instruments.
- Gisat will provide near real time pictures of large areas of the country, under cloud free conditions, at frequent intervals.
Codes:
Correct
The ISRO is designing a Geo imaging satellite (Gisat) which is planned to be launched during 2016–17. It will carry a GEO imager with multi–spectral (Visible, near–infra–red and thermal) and multiresolution (50m to 1.5 km) imaging instruments. It will acquire images of a geographical strip and also provide near real time images of large areas of the country.
