What is an RTK Drone?
An RTK drone is a type of unmanned aerial vehicle (UAV) that utilizes Real-Time Kinematic (RTK) technology for precise positioning and navigation. It is equipped with a GNSS (Global Navigation Satellite System) receiver, typically a high-precision GPS module, which allows the drone to achieve centimeter-level accuracy in its positioning.
RTK technology is a technique used to enhance the accuracy of GPS positioning. It works by correcting errors caused by atmospheric interference, signal delays, and other factors that can affect GPS accuracy. This is achieved by using a fixed base station, which serves as a reference point and calculates its precise coordinates using signals from multiple GNSS satellites.
The base station then sends correction data to the RTK drone in real-time, enabling it to adjust its GPS coordinates accordingly. This continuous feedback loop between the base station and the drone ensures that the drone’s position is highly accurate and reliable, even in challenging environments or areas with limited satellite visibility.
RTK drones offer a significant advantage over traditional GPS-enabled drones that rely solely on the satellite-based positioning system. While standard GPS can provide accuracy within a few meters, RTK technology can achieve accuracy down to the centimeter level. This level of precision opens up new possibilities in industries that require highly accurate measurements and mapping.

How does RTK Technology Work?
RTK (Real-Time Kinematic) technology is a technique used to enhance the accuracy of GPS (Global Positioning System) positioning. It works by correcting errors caused by atmospheric interference, signal delays, and other factors that can affect the accuracy of GPS measurements.
At the core of RTK technology is a process known as differential positioning. It involves comparing the measurements acquired by a stationary reference receiver, called the base station, with those acquired by the moving receiver, such as an RTK drone. The base station is positioned at a known location with precisely determined coordinates.
The base station receives signals from multiple GNSS (Global Navigation Satellite System) satellites, such as GPS, GLONASS, Galileo, or BeiDou. These satellite signals contain information about the precise location of each satellite, known as ephemeris data.
Using the ephemeris data, the base station calculates its own precise position, also known as the reference position. This position serves as a reference point for the RTK drone and is used to estimate the errors present in the raw GPS measurements due to factors like atmospheric delays and clock inaccuracies.
The base station then transmits correction data to the RTK drone in real-time. This correction data includes the estimated errors in the GPS measurements and is used by the drone’s onboard receiver to adjust its own GPS positions.
By applying the received correction data, the RTK drone can compensate for errors in its measurements and achieve highly accurate positioning. The continuous feedback loop between the base station and the drone allows for real-time adjustments, ensuring that the drone’s position remains precise even as it moves and encounters environmental influences.
For the RTK technology to work effectively, the base station and the drone must be within a certain range of each other. This range is typically limited to a few kilometers, depending on the specific RTK system being used and the signal quality.
The accuracy achieved by RTK technology is significantly higher than that of standard GPS positioning. While GPS can provide position accuracy within a few meters, RTK technology can achieve accuracy down to the centimeter level. This level of precision makes RTK drones ideal for applications that require highly accurate measurements, mapping, and surveying.
In addition to the base station, some RTK systems also use a virtual reference station or network of reference stations. These virtual reference stations calculate and transmit the correction data to the RTK drone, offering greater flexibility in terms of positioning and access to correction data even in areas where physical base stations may be limited.
Overall, RTK technology plays a crucial role in enabling RTK drones to achieve exceptional accuracy in their positioning. By continuously receiving correction data from a reference station or network of stations, these drones can overcome the inherent errors of GPS measurements and deliver precise results that are essential in a wide range of applications.
