The new D-RTK 3 Multifunctional Station integrates high-performance antennas and receiver modules capable of tracking and resolving data from major global satellite navigation systems, and it supports multiple data transmission links. With these outstanding features, it can serve as a base station to provide centimeter-level positioning for multiple drones simultaneously or extend the operational range of drones in relay station mode. Additionally, the new rover station mode, combined with the DJI Enterprise app and DJI Terra, provides a comprehensive solution for high-precision aerial surveying applications, ensuring a secure and accurate operation.

System Accuracy*

• Base Station Mode (Broadcast Mode) and Relay Station Mode
  
  Base Station Accuracy:
  Single Point Accuracy (Uncalibrated):
  Horizontal: 1.5 m (RMS)
  Vertical: 3.0 m (RMS)
  
  Satellite-Based Differential Accuracy:
  Convergence Time: 20 mins
  Horizontal: 30 cm (RMS)
  Vertical: 40 cm (RMS)
  
  Network RTK Calibration**:
  Horizontal: 1.0 cm (RMS) + 1 ppm
  Vertical: 3.0 cm (RMS) + 1 ppm
  
  Rover Station Mode
  
  RTK Accuracy (Fixed Survey)*:
  Horizontal: 0.8 cm (RMS) + 1 ppm
  Vertical: 1.5 cm (RMS) + 1 ppm
  
  RTK Accuracy (Tilt Survey)***:
  Angle Range: 0° to 60°
  Horizontal: 8 mm + 0.7 mm/° tilt (accuracy <2 cm within 30°)
  
  * Measurement accuracy depends on various factors. This value is obtained under normal conditions with an unobstructed view, good satellite distribution, low ionospheric activity, and no electromagnetic interference or multipath effects.
  ** Base station calibration coordinate accuracy depends on various factors. For surveying, high-precision flight paths, etc., it is recommended to calibrate during periods of inactive ionosphere, in open, unobstructed environments with no electromagnetic interference or multipath effects, using four or more GNSS systems.
  *** Intense vibrations and rapid rotations can affect the accuracy of the inertial measurement unit.
