Show Hint
Remember:
\[
\boxed{
\text{Along-track Stereo}
=
\text{Fore Camera}
+
\text{Aft Camera}
+
\text{Single Satellite Pass}
}
\]

- Imaging same area from two different orbital passes
- Using two different satellites to image same area
- A single satellite acquiring two images (e.g., fore and aft) in same pass
- Rotating sensor in across-track direction

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Along-track stereovision is obtained by capturing the same ground area using forward-looking and backward-looking cameras mounted on the same satellite during a single orbital pass.
Step 1: Understand the imaging mechanism. The satellite carries two cameras:
• Fore-looking camera
• Aft-looking camera Both image the same area from different viewing angles.
Step 2: Identify the correct mechanism. Thus, \[ \boxed{\text{Along-track stereovision is achieved using fore and aft images acquired in a single pass}.} \] Therefore, the correct option is \[ \boxed{(C).} \]
