18.7.2. RTK and PPK Drones

Try these first

1. 1.

   What does RTK stand for?

   Hint

   Consider what happens in real-time situations.

2. 2.

   Define GCP.

   Hint

   Think about anchoring a survey.

3. 3.

   What does PPK stand for?

   • Real-Time Kinematic
   • Post-Processed Kinematic
   • Precision Point Kinematic

   Hint

   Focus on the 'post' aspect of the name.

4. 4.

   True or False: RTK drones use corrections after the flight.

   • True
   • False

   Hint

   Consider the immediate nature of RTK.

5. 5.

   A construction project requires detailed topographic data captured in a heavily built urban area. What drone technology would be optimal, RTK or PPK? Justify your choice.

   Hint

   Analyze the operating environment.

6. 6.

   Explain how implementing GCPs enhances the accuracy of both RTK and PPK systems in surveying projects.

   Hint

   Consider how ground references help in data accuracy.
