What is RTK in drones?

Why RTK is Essential for Precision Drone Work

Real-Time Kinematic (RTK) technology has revolutionized the way drones are used for precision work. RTK ensures that your drone can achieve centimeter-level accuracy, making it indispensable in applications such as surveying, mapping, and construction monitoring.

RTK Explained: Precision Flying with Drones

RTK technology enhances a drone's GPS capabilities by correcting for errors caused by atmospheric conditions. This correction is achieved through the use of ground-based reference stations that send real-time corrections to the drone’s onboard receiver, significantly improving positional accuracy.

How RTK Works in Drones

• Reference Station: A stationary base station continuously monitors satellite signals and sends correction data via radio or cellular networks.
• Differential Correction: The drone receives this correction data, which it uses to adjust its GPS position for enhanced accuracy.

RTK vs Non-RTK: Which Drone is Right for You?

The choice between an RTK-equipped drone and a standard non-RTK model depends on the level of precision required. While non-RTK drones are suitable for general use, RTK drones offer unparalleled accuracy essential in professional applications.

Key Differences

• Accuracy: RTK drones can achieve centimeter-level accuracy compared to meter-level accuracy with non-RTK drones.
• Data Quality: RTK ensures higher quality data, making it ideal for detailed surveys and mapping projects.
