18.1.3.2. GPS and IMU systems

Try these first

1. 1.

   What does GPS stand for?

   Hint

   Think about how it helps with locations.

2. 2.

   What information does an IMU provide?

   Hint

   Consider what keeps a drone stable.

3. 3.

   What is the primary function of a GPS in aerial surveying?

   • A: To measure the drone's speed
   • B: To provide precise location data
   • C: To collect thermal data

   Hint

   Think about what helps place the UAV in a geographic context.

4. 4.

   True or False: IMUs are only used for navigation.

   • True
   • False

   Hint

   Consider additional applications of IMUs.

5. 5.

   Analyze a situation where a UAV loses GPS signal during data collection in a crowded urban area. Discuss how it can still function effectively through IMU.

   Hint

   Consider how different sensors can support each other.

6. 6.

   Design a protocol for conducting aerial surveying in a dense forest where GPS reception is problematic. How would IMUs facilitate this process?

   Hint

   Think about how you would ensure accurate results despite signal loss.
