Question

Which of the following equipment is used to determine the sensor position in aerial and satellite-based LIDAR platforms?

• A. \(\text{DIAL} \)
• B. \(\text{LRA} \)
• C. \(\text{IMU} \)
• D. \(\text{Doppler LIDAR} \)

Hint:

IMU (Inertial Measurement Unit) is critical for real-time navigation and sensor positioning in aerial and satellite LIDAR systems.

Answer 1

The Correct Option is C

Step 1: Understanding sensor positioning in LIDAR. Aerial and satellite-based LIDAR platforms require precise positioning to map terrain accurately. 
Step 2: Explanation of IMU (Inertial Measurement Unit). 
- IMU (Inertial Measurement Unit): Measures acceleration and rotation to determine sensor orientation and position. 
- DIAL (Differential Absorption LIDAR): Used for atmospheric gas measurements. 
- LRA (Laser Retroreflector Array): Used for precise satellite tracking. 
- Doppler LIDAR: Measures wind speed and direction. 
Step 3: Selecting the correct option. Since IMU is responsible for sensor position tracking, the correct answer is c. IMU.
