What is RTK and PPK and why are they used in drone operations?

• A. Both refer to battery management techniques.
• B. Real-Time Kinematic and Post-Processed Kinematic enhance GNSS accuracy to centimeter level, improving mapping and precision tasks.
• C. Techniques for flip maneuvers.
• D. Standards for flight altitude.

Answer: (B)

RTK and PPK are techniques that boost GNSS positioning accuracy for drone data collection. Real-Time Kinematic provides corrections during the flight from a nearby base station or network, giving centimeter-level positioning accuracy as you fly. Post-Processed Kinematic captures similar observations and applies corrections after the flight, producing the same high accuracy even when real-time corrections aren’t available. This precision is crucial for mapping and precision tasks because it georeferences imagery reliably, reduces the need for extensive ground control points, and helps ensure consistent alignment across datasets. They aren’t about battery management, flip maneuvers, or flight altitude standards, which is why those options aren’t relevant.
