The Resourcesat-2, the Youthsat and the X-Sat were in good health and working satisfactorily, they said.
The Resourcesat-2, an advanced remote-sensing satellite, will replace the Resourcesat-1, which was put in orbit in October 2003. The Resourcesat-2 has been fitted with three sophisticated cameras, and the first images of the earth are expected on April 28. Though the Resourcesat-1's life was five years, it was still sending pictures of the earth.
The images from the Resourcesat-2 will be useful in estimating the acreage of crops and the stress they are under, keeping a surveillance on pests, locating groundwater, identifying schools of fish in the sea, predicting the advance of glaciers, monitoring water bodies and keeping a watch on deforestation or changes in the rural and urban landscape.
