India is all set to launch its sixth satellite in the series of Cartosat-2 satellites. Cartosat-2 satellites are highly sophisticated remote-sensing satellites. It is developed to obtain high-resolution scene-specific spot imagery. The images from the previous satellites were getting used for civil work, but this new launch placed a different type of satellite in the orbit.
Cartosat satellites were facing doubts of being spy satellites of India, who can take high-resolution pictures of different places of near the capital which could be used for military purpose. The fact got cleared when the involvement of the satellite in the information gathering of the cross-border raid of Indian Army came out. Now ISRO launched the sixth satellite in the series which is particularly established in the space for the use of military of the country.
The satellites have attended very sophisticated level of automation, the user just needs to program the satellite according to its need and the satellite will take pictures according to required imagery. A dedicated imaging satellite for the military is a big step by India, the satellite will keep keeping track of any change in man-made or geographical features along its land and maritime borders.
Cartosat-2E which was launch on Friday can images of up to 100 cm in resolution, previously India use to buy images from Ikonos, which is a commercial Earth observation satellite. Ikonos offered 80 cm in resolution as compared 100 cm of resolution offered by indigenous satellite. Cartosat-2E is very cost effective, it is 20 times cheaper than Cartosat-2E. Ikonos use to charge about $20 per square km of imagery while the Cartosat can do the according to the needs in very less price, moreover, it gave country self-reliance in imaging capabilities.
