9.2.2. System Components

Try these first

1. 1.

   What is the primary function of the laser scanner?

   Hint

   Think about what happens to a light beam when it hits an object.

2. 2.

   What role does GNSS play in ALS?

   Hint

   Consider what technology helps GPS devices locate their position.

3. 3.

   What does the laser scanner in ALS do?

   • Emits radio waves
   • Captures data using lasers
   • Measures temperature

   Hint

   Consider the type of sensor used for measuring distance.

4. 4.

   True or False: The data storage unit is not essential for ALS.

   • True
   • False

   Hint

   Think about what happens to data if it is not stored.

5. 5.

   Consider a scenario where the laser scanner fails during a flight. What impact would that have on the collected data, and what might be possible solutions for this issue?

   Hint

   Think about the importance of data completeness in mapping.

6. 6.

   If the GNSS signal is disrupted during data collection, how can the ALS still maintain accuracy? Discuss the methods that could be employed.

   Hint

   Consider fallback mechanisms in technology.
