Overview
Real-Time Kinematic (RTK) GPS is a differential satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems. It relies on a single reference station (base station) and a mobile receiver (rover) to provide real-time corrections, resulting in centimeter-level positioning accuracy.
By using an RTK-enabled drone and base station, you can achieve:
Horizontal Accuracy: 1-2 cm
Vertical Accuracy: 2-4 cm
This level of precision is essential for high-accuracy aerial mapping, surveying, and construction site monitoring, as it ensures that every map pixel and 3D point is geolocated with extreme fidelity.
How RTK Works
RTK systems function by measuring the phase of the signal's carrier wave in addition to the information content of the signal. The base station transmits its known location to the drone in real-time, allowing the drone to calculate its relative position with high precision.
