Updated On: Jun 16, 2025
- Stadiometer or Satellite Stadiometer
- Altimeter or Satellite Altimeter
- Space Theodolite
- LISS
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Satellite altimeters are used to measure the height of water surfaces. They send radar pulses to Earth's surface and measure the return time to calculate elevation, useful for tracking river and reservoir water levels.
