The Correct Option is A
Solution and Explanation
Concept:
Cartosat-1 is an Indian remote sensing satellite specially designed for cartographic applications.
It carries two panchromatic cameras (fore and aft) that simultaneously acquire stereo images during a single satellite pass.
Step 1: Understand along-track stereo imaging. The two cameras are inclined in opposite directions, enabling
• Along-track stereoscopic imaging.
• Generation of Digital Elevation Models (DEMs).
• Three-dimensional terrain mapping.
Step 2: Identify the appropriate satellite. Hence, \[ \boxed{\text{Cartosat-1 is specifically designed for single-pass along-track stereo imaging}.} \] Therefore, the correct option is \[ \boxed{(A)\;\text{Cartosat-1}.} \]
